Thrust block R2. How to divide a hard drive into partitions Work with disks using special utility programs

So the question arose before you, how to partition a hard disk into sections. The reasons may be different, for example, you purchased a new HDD to increase the permanent memory of an existing computer, or you bought a new laptop, but without a pre-installed system, and you yourself have to install the Windows shell, or you simply did not have enough disk space for newly installed programs .

The main ways to divide the space of hard drives

Regardless of the reasons that prompted you, you want to partition the hard disk into sections yourself, but you have little idea how this is done in practice. Here we will try to help you by telling you not only about the main ways to properly partition a hard drive, but also pointing out certain nuances and difficulties that you may encounter during this difficult work.

Consider how to divide a hard drive of any kind (HDD or SSD) in three ways, namely, using:

• standard utilities running Windows installed on your computer;
• special programs for working with various storage media;
• Windows PE boot shell.

So, let's get started and try to follow the sequence of actions exactly, otherwise, this can either lead to the repetition of operations for a new drive, or the loss of important data when working with existing storage media.

We partition the disk with a standard Windows utility

This way of working with drives is not very complicated and, most importantly, does not require third-party programs. It is suitable for partitioning both the main “C” drive and for partitioning an external HDD into partitions. All versions from Windows XP to Windows 10 have this utility for working with storage media.

So, to work directly with hard drives, you need to open the standard Windows shell utility, and it can be called on the desktop in two ways:

In the opened window " Disk Management”All storage devices currently connected to your computer, including flash memory, should be displayed.

We move the mouse cursor over the desired partition and right-click the context menu for this disk. And here, depending on what we want to do, we decide on the team we need in the future.

Divide the disk into two

If this is one main “C” drive, then this is an easy way to split a hard drive into two and with absolute certainty not lose system information. To do this, perform the following steps:

Everything, the main disk is divided into two sections.

Partitioning a disk

But how to divide a hard drive into partitions, in the case of a new, just purchased drive, working with this standard utility is also not difficult, but the algorithm of actions will be slightly changed. The sequence of actions will be as follows:

It is worth remembering here that the disk system MBR allows you to create up to 4 partitions per hard drive.

Working with disks using special utility programs

The following universal software utilities for working with various storage media have found the greatest popularity among users, namely:

• Acronis Disk Suite;
• Paragon Partition Manager Professional;
• AOMEI Partition Assistant Technician Edition.

These utilities are specially adapted to perform almost all basic operations with HDD, SSD and other storage media. They have a fairly clear interface designed to work with both specialists and ordinary users.

Partition a disk into partitions using such universal utilities, we will analyze it using an example program AOMEI Partition Assistant, which you can install on your computer as a standard application, or use it from portable mode.

And also for comparison, we will show the operation of the utility in two modes when dividing the main disk into two and dividing the new hard disk into several partitions.

We open the program and see a window with extensive information on all connected storage media and their sections.

We divide by two

The algorithm for partitioning the main hard drive "C" consists of a set of sequential commands:

After rebooting, having completed all the operations, the system will boot, but with the main disk divided into two parts.

Sharing a new disk

Typically, the new HDD will represent unallocated space and will only be visible in the program window.

First, we must clearly designate the disk with which we will work by hovering the mouse cursor and obtaining the corresponding color gradation of the position. But in case of an error, you can lose all important information on a randomly selected existing storage medium.

The algorithm for working with other universal programs for resizing various storage media is very similar to the example above. The only significant difference will be the program interface and menu layout.

Partitioning the main disk using the Windows PE boot shell

If you decide to install a new operating system or completely update the old one, and the existing partition sizes of the main HDD do not suit you or do not meet the necessary requirements, then it is better and easier to reformat by going into the computer from a special simplified shell.

If desired, various versions can be downloaded from the Internet, and they are freely available there and are equipped with a set of all the necessary portable programs to work not only with storage media, but also have a whole set of various useful utilities. For example, you can take a distribution kit from the site https://diakov.net/8305-adminpe-30.html, which does not require additional registration from the user.

After booting to USB or CD / DVD media, we boot the system through the key to call up the menu, which has a choice of boot device. As a rule, this is the function key F11, after pressing which, and select our media.

After loading the portable, a desktop will appear, almost completely repeating the familiar Windows shell, but with pre-installed software modules.

We open a universal program for working with various storage media and work according to the example given earlier in the background and without unnecessary reboots.

The main advantage of the shell is that program modules are not related to hard drives in any way, which allows you to perform all possible operations to reformat them in any possible way without any restrictions.

Conclusion

In this article, we learned how to partition a PC or laptop disk in different ways. Examples were considered: how to divide a hard disk into 2 parts, and how to create partitions on a hard disk. In similar ways, you can partition an external hard drive. Just connect it to your computer and follow the same steps.

2.5" and 3.5" Hard Drive Solutions

Hard drives in two form factors 2.5" and 3.5" - practical differences and applications.

Often, instead of specifying a specific hard drive form factor in inches(and the double quote denotes exactly inch), computer hardware vendors use the abbreviations SFF and LFF, abbreviations for Small Form Factor and Large Form Factor, respectively. It is easy to guess that any (both SATA and SAS) hard drives of a smaller form factor 2.5" received the designation SFF HDD and more 3.5" - LFF HDD. It's no secret that in modern high-performance hard drives of 3.5" and 2.5" form factors, manufacturers use platters of the same size - from 2.5" HDD. Therefore, often, both the capacity and performance parameters of 2.5" and 3.5" hard drive models from the same manufacturer look the same Moreover, some manufacturers have announced that they are no longer producing high-performance 3.5" HDDs, leaving top models of HDDs in 2.5" form factor only. Availability of high-performance 3.5" HDDs is steadily declining. Based on the realities of the modern market, manufacturers consider it economically inexpedient to use more than 2 platters inside one hard drive. For reference, it is possible to install up to 3 platters in a 2.5" hard drive (15mm high), and up to 5 platters in a 3.5" HDD.

2.5" drive

3.5" disk

What about those consumers who cannot or do not want (for various reasons) to use modern hard drives of the 2.5" form factor? Manufacturers offer an intermediate solution - the use of 2.5" hard drives in a 3.5" form factor. As a 3.5" hard drive, a regular 2.5" hard drive is offered, installed at the factory by the manufacturer in a special metal mounting case - a carriage. It should be noted that the removal of this hard drive from the mounting case by some manufacturers is not compatible with the warranty. Of the undoubted advantages of this design, it should be noted that the engineers of manufacturing companies accurately calculate the dimensions and rigidity of the structure, the location of connectors and mounting holes is standard for 3.5" hard drives, and optimal cooling of the hard drive installed inside is ensured.

If a move to a smaller form factor is inevitable, what will consumers get from moving to a 2.5" hard drive form factor?
What are the differences, pros and cons of disk subsystems based on hard disks of various form factors and their scope? In two words, what's the difference?

Obviously, the smaller the size of the hard disk, the more such hard disks must fit inside the server.

Today, the following number of hard drives are traditionally installed in rack-mount servers:

In general (as can be seen from the table), it is possible to install 2 times more 2.5" hard drives in servers compared to servers of the same size, but with 3.5" hard drives.

As mentioned earlier, in the segment of enterprise-class hard drives, the maximum capacity of drives of two different form factors is the same, based on this, the use of a disk subsystem with 2.5" bays allows you to double the maximum total storage capacity. And even when using low-priced hard drives range, in which, today, the maximum capacity of 3.5" form factor hard drives is about 2 times larger than that of 2.5" drives, the maximum capacity of disk subsystems with bays of different form factors will be approximately the same.

As an additional bonus of using 2.5" hard drives, it is obvious that due to smaller dimensions (a 2.5" drive is less than a 3.5" drive in depth), the disk subsystem in the server occupies a smaller volume, which allows manufacturers to slightly reduce the size of servers. It should also be noted that most modern SSDs (solid state drives) are available in the 2.5" form factor and the use of 2.5" bays in the server guarantees compatibility when installing SSD drives, and, most importantly, in the future - with a possible server upgrade.

For comparison, two 2.5" hard drives with 10.000rpm (revolutions per minute) enterprise class on a good RAID controller will outperform one 3.5" drive with 15.000rpm in performance. At the same time, the price of two 2.5" 10.000rpm drives with a capacity of 300GB each and one 3.5" 15.000rpm drive with a capacity of 600GB will be approximately the same.

Such a parameter as the linear read / write speed on external tracks, theoretically, should be higher for 3.5" hard drives than for 2.5" hard drives (at the same spindle speed and at the same recording density) simply due to the physically larger size of the platters, but in reality there are differences insignificant, since high-performance hard drives of different form factors often contain platters of the same size.

In general, the more hard drives in the server, the greater the power consumption (more powerful power supplies should be), and the greater the heat dissipation (the server's ventilation system and cooling costs should be more powerful). However, compared to 3.5" hard drive models, modern 2.5" hard drives have 2 times less power consumption (in all modes) and, as a result, less heat dissipation and cooling costs. Thus, a server with 24 2.5" hard drives consumes electricity and heats the environment less than a server with 12 3.5" hard drives.

The reliability of hard drives is always given great attention. Due to the reduction in size (and additional engineering solutions) 2.5" hard drives have increased resistance to vibration and mechanical stress. This is confirmed by the manufacturers themselves, the time between failures (MTBF) for the latest models of 2.5" hard drives is 2 million hours, compared to the best models of 3.5" hard drives, whose MTBF is declared at the level of 1.3-1.6 million hours.

And lastly, despite the fact that this is not relevant in servers, 2.5" drives produce slightly less noise during operation compared to 3.5" models.

As a result, we can briefly formulate the pros and cons, as well as the scope of hard drives of various form factors.

Advantages of hard drives in different form factors

3.5" LFF - more volume of one disk, less price per gigabyte:
• at the same recording density, more information is placed on a larger platter
• the maximum capacity of one HDD is larger (in the low price range hard disk segment)
• cheaper cost per gigabyte of disk space

2.5" SFF - more capacity and performance per unit of space occupied by a server or storage system in a rack:
• 2 times more storage capacity in a limited space - smaller dimensions and, as a result, a higher capacity density per unit of space (GB/cm3) or per unit of server rack size (GB/Unit)
• higher performance of the storage system in a limited space - smaller dimensions and, as a result, a higher I / O density of the disk subsystem per unit of space (IOPS / cm3) or per server unit in the rack (IOPS / Unit)
• 2 times less power consumption (in all modes) and, as a result, less heat dissipation and cooling costs
, modular and blade servers
• in systems with high performance of the disk subsystem due to a large number of fast hard drives -
• on systems with a large number of RAID groups -
• in systems with maximum reliability of all components -
• in systems with low or limited power consumption -

Below is a table for calculating rectangular plates of constant stiffness with Poisson's ratio μ = 0.3. The plates are rigidly clamped on two sides and hinged on the other two sides, while the rigidly clamped and hinged sides converge at two diagonally opposite vertices of the rectangle. The plates are subjected to a uniformly distributed load q:

Table 394

And a few more explanations for this table:

1. The values ​​of the coefficients were checked according to various engineering reference books, in particular, according to the book "Calculation of plates" by D.V. and E.D. Weinbergov.

2. h- plate height. Often, letters are used to indicate the length and width of the plate. A And b, however, I decided to designate the length of the plate - l, and the width of the plate - b. And although this looks somewhat paradoxical, since the length of the plate is less than or, in the boundary case, equal to the width, nevertheless, this allows (rather conventionally) to consider the plate as a beam.

3. M x X. At the point ABOUT z. Respectively Mz- diagram of moments acting on sections perpendicular to the axis z. At the point ABOUT currently trying to rotate the cross section around the axis x. The greater the ratio l/b, the more the type of diagram changes Mz. Minus in the value of moments in points H 1 And TO(on the rigid supports of the plate) means that at these points the tension will be in the upper zone of the plate.

4. The table does not contain the values ​​of some coefficients for plates with an aspect ratio of more than 2, for the reason that such plates are easier to consider as just a beam with rigid clamping on one support and hinged support on the other, however, if you want to make more accurate calculations for the plates with a large aspect ratio, you can take the value of the coefficient lower in this column.

5. When the value of Poisson's ratio decreases, the value of some coefficients will increase. For example, when μ = 1/6 the value of the coefficients k 2 and k 3 (with the aspect ratio l/b = 1) will be 11% greater than that given in the table, and the value of the coefficients k 4 and k 5 will be the same. The reason for this is the change in the geometry of the cross section (and, accordingly, the change in the moment of inertia of the cross section) with a change in the Poisson's ratio. Theoretically, it would be possible to give another table that allows you to determine the values ​​​​of the coefficients at a lower value of the Poisson's ratio, but I decided not to do this. For people who are engaged in the calculation of a single structure only once in their life, simplicity and safety margin are much more important than the nuances of rather complex plate calculations. Well, for everyone else, there are endless expanses of the Internet and libraries.

6. For intermediate values ​​of the ratio l/b coefficient values ​​are determined by interpolation.

Hello! Please, tell a simple computer user to deal with hard drives and the possibility of their autonomous operation...
The point is the following. It became possible to install a second hard drive on your PC, so that the first one was exclusively for the OS + necessary programs + frequently used files and (documents, technical diagrams, etc.), and the second for home archive (video, photos, films, rarely used files.
I successfully installed the second hard drive myself (the OS sees and maintains it well) ... But there is one problem here. This hard drive should be used from time to time, but it turns out that every time the computer is turned on and off, the OS starts it anyway - and this, after all, affects the resource!
How to make sure that this, let's call it an "archival" hard drive, does not start up unnecessarily? Is it possible?

In fact, it was this option that I considered first, and here's why. Now my system unit is (with the wide side) right behind the monitor and the back (free) side (for certain reasons) without a cover (i.e. there is free access to the hardware). The cables of both HDDs are easily accessible. In general, everything is predisposed to removing / inserting connectors. But realizing that everything would quickly become unusable, so I asked myself not a mechanical, but a software switch on and off of the hard drive. Well, it turned out that this, unfortunately, is impossible.
So, YUM, I'll have to follow the path already discussed...

YUM | April 19, 2015, 03:32 pm
in the order of discussion: why not go the mechanical way? Well, for example, lengthen the power cord. Take out dad / mom outside and as unnecessary, just open the pads. The train, however, will stick out all the same in the "mother", but, I think, further than the show: "unknown device", Oska will not go. I remember sticking fans into free blocks on the PSU. For outdoor use. One to blow - on me, the second - in the body. For, it happened, both of us and the computer overheated ... :-)

Nicholas | April 8, 2015, 13:58
Nick Nick, thanks for the reply. From the answers, I realized that the second hard drive integrated into the PC will still be polled by the OS for any of its actions. And therefore, in order to eliminate "unproductive" inclusions and disconnections, it is necessary to exclude it from the direction of one OS. That is, it is either a PC with two motherboards (and different OS), or a second PC, or an external hard drive, or a NAS ...

Nick Nick | April 7, 2015, 14:47
I did it this way, in the system unit there is a 500 gb disk divided into two partitions on one partition, the system on the other, downloaded movies, etc. In a beautiful plastic case called an external HDD box, there is a second (standing right on the table) hard drive also for 500. Moreover, it has an autonomous power supply switch on the case. There are photos and archives on it, and it is connected with a switch when needed, and when not needed, it is turned off by a switch on the body. It is connected to a USB computer (comes with a box in the kit). The system sees the disk as a large flash. I took this box and watch photos and videos DVD or wherever there is USB.

Nicholas | April 7, 2015, 08:19
Nick, maybe you are right about something. But then again, I do not need a backup disk (did I name it correctly?), which will be stored in a cabinet.
There were 2 hard drives available (500 GB and 2 TB). On the first one, I placed the OS with accompanying programs (which are not yet installed all the necessary ones). By the way, as Dima Svinkin mentioned, the system disk was divided into two logical ones - for the OS itself and for different files needed in everyday work. And the second HDD (2 TB) is gradually filled with "house stuff" (photos, videos, films, music, rarely used documents, drawings, etc.).

As a result, after turning on the PC, after a while (as you mentioned, Nick) the "dvuhterrabyte" "falls asleep", I don't even know when this happens. On the one hand, this is good - the hard drive is not used, and on the other hand, the problem I describe arises.
Nick, I can’t buy an external drive yet (especially now they are very expensive, and there are already 2 TB available). It's just that I have the opportunity to get a small system unit - I'll probably have to "dance" from this option.
By the way, Nick, I'm certainly not an IT specialist, but all the same, everywhere it is said that the hard drive should be treated with care, including for him it's better to "spin" all day than to start and stop.

So, in summary, we can say the following:
1) separate management on one computer, with one OS, two physical hard drives (without good system knowledge and access to BIOS) is almost impossible.
2) to solve the problem I am describing, it is proposed to either physically turn off the second HDD (which is unrealistic), or use an external HDD, or you can use the second system unit of a small form factor.
Is everything right?

Nick | April 6, 2015, 22:47
For Nikolai: "professor" on one of the IT sites - advised you correctly. It is best to have 2 disks in the system. But they are used for something completely different. For example, only the system is on one disk. And if the system crashes or you need to restore it from a backup image six months ago, then your current documents will not be affected in any way, because. they are on a different drive. You won't lose anything. Or you need to check for errors or defragment the system disk - the operation will be performed much faster in time on a small system disk (where only the system) than on a huge shared disk, where in addition to the system there is a bunch of your documents, pictures, videos, etc. In short , 2 disks are used for data spacing - and this is necessary for the convenience of system maintenance.

I don't know what you are afraid of switching disks on and off. There is nothing to worry about, modern disks are designed for this, they can even turn off and fall asleep if they are not accessed for a long time.

Well, if you want to turn off the drive yourself, then buy an external drive. For example, I use an external USB-3 drive. It works quickly to turn it off - you just need to remove the connector with a cord from the computer's socket (it is inserted into the USB flash drive connector).

Nicholas | April 6, 2015, 20:54
Thanks to everyone who answered my question. A separate "curtsey" for Alek55sandr5 - it seems that you immediately "caught" the essence of the issue.
Now it becomes clear that if two (3.4) hard drives are connected to one OS (which the system "sees" as separate physical drives), then every time you turn it on, turn it off or reboot, the system will always start them all (which, of course, reduces their resource, because for a hard drive one of the most difficult modes is start-up, when the spindle spins "pancakes" Right?)
It is strange that at one time, some "professor" on one of the IT sites, "advised" to have two separate hard drives in his PC (and not in some kind of ride array, namely two separate physical ones - one for OS and related programs, and another for home videos, photos, books, document archives and other relatively rarely used files). So I "bought" this "call".
That is, for me it would be the right decision: a separate small-sized system unit, from which to make something like a NAS and connect it as needed? This is the only way I can save the second hard drive from unnecessary inclusions. Right?

Put there a swap file and a folder for temporary files. The disc will give back.

Svinkin Dima | April 5, 2015, 04:43 PM
Strongly disagree with you! A home archive must be created and stored on an external hard drive. What size is your system (physical disk)? For OS + various programs, 100-150 GB is usually enough, and for many users the system (logical) one is even several times smaller than these sizes. If you had one physical disk in your computer with a nominal size of 320 GB or more, then it is unreasonable to define this entire volume under OS + programs. It needs to be divided into two partitions (two logical drives) C:\ and D:\. Disk C is the system drive, and on drive D: \ you should place folders for temporary files of all programs, folders for downloading from the Internet, folders for saving files created in different programs and a temporary archive of the most popular files. Any extra physical device in a computer can turn into a headache at any time - this is a practice.

Alek55sandr5 | April 5, 2015, 15:50
As far as I know, unfortunately it is impossible to completely turn off the hard drive if it is connected to a PC. Each time you start the operating system, the hard drive will boot with it and its resource will slowly wear out. You can copy some files to this hard drive and remove the connected cables from its connector. Thus, it will be completely disabled and its resource will be larger. But of course, if this option suits you.

What is a roller?

ricinus : The roller is a complete assembly of one wheel, wheel bearings, yoke, axle and nut, (and optional: threaded guards, brakes, twist locks, springs...), all assembled together as one complete unit. There are two main types of rollers.

Swivel Roller : Consists of all the components of the wheel plus the raceway which contains the balls or bearings that allow the wheel to spin.

fixed wheel: Either a stationary roller or stationary rollers consist of all roller components but do not have a raceway. (Therefore, it can only roll in two directions, in a straight line).

swivel joint Radius : Distance is measured horizontally from the center of the tread or top plate to the trailing edge of the wheel. IN

Tread Width : The width of the wheel at the point of contact with the floor.

Wheel size : Determined by wheel diameter. For example, if you ask about 6" casters, we'll assume you're talking about 6" casters, even though you think the overall height of the casters would be 7" to 7-1/2".

Overall Height : Vertical distance from the floor to the top of the mounting plate or top of the turntable for the wheel stem. End product working load height

Friction or cam brake : Stops (or slows down) the wheel by applying side pressure between the wheel and the fork. Not the most positive type of brake, but relatively cheap and works in many applications.

Top lock brake light : The baking tab is usually on the side of the wheel, but sometimes on the top, under the plate or rod mount. The petal includes a spacer that clamps on the wheel for a very positive lock. Since the pad is metal, this brake may be less effective when used with a metal wheel. This brake is sometimes called the tread brake.

Turn signal : It is switched on through the petal, which, when suppressed, blocks the wheel and the turning section of the wheel. Very positive braking action but costs more than other types of brakes. With the wheel and turn locked down, the roller becomes a foot with no movement.

Rotary lock or brake Direction lock : It usually has a pin that pulls out and when inserted back into the turn section prevents the wheel from turning. This turns the Swivel Castor into a fixed wheel. It usually has 4 positions for locking rotation when shifted by 90 degrees. Very useful for some applications and can be combined on some casters with a top lockout brake. Also called "Twist Lock Position" sometimes.

Side lock brake light : Another name is used for both friction lock and overhead brakes when the brake petal is on the side of the wheel.

Kingpin : The kingpin roller is the pin in the center of a furniture wheel with a plate that holds the plate to the wheel forks. On Casters, the radius is from the trailing edge of the wheel to the center of the mounting bar.

There are many styles of videos, and not all of them will easily fit the main description.
