Disk Management encountered an error during the operation. Internet guide - all the fun on the web. Management of logical drives "hard drive"

Faced the following problem: when connecting any removable external hard Windows USB disk / stick does not assign a drive letter to it. When a drive is connected, a message appears stating that a new device is being installed, the drive appears in Device Manager, but does not appear in Explorer.

To make the drive available to the system, it must manually assign a drive letter each time through the Disk Management console. To do this, you need to open the console Computer management (via the Win + X menu) and go to the section Storage devices -> Disk management... Find the connected USB removable device in the list of drives. As you can see, the disk is healthy, one partition with the NTFS file system has been created on it, but it is not assigned a drive letter. To assign a letter to it, click on the section right click mouse and select the menu item " Change drive letter or drive path».

In the window that appears, click the " Add to", Select" "and in the drop-down list select the letter you want to assign to the drive (for example, F :) and click OK.

After that, the connected USB disk appears in the explorer with the assigned beech disk. However, after disconnecting USB devices or restarting the computer, it is again not assigned a drive letter. You have to assign the letter again manually through disk management - which is a bit annoying.

Advice... Make sure Windows detects the partition (s) on the mapped drive and that the partition is formatted as a file nTFS system/ FAT32 /. If, or the disk is unpartitioned, most likely the USB disk is just new or the partition table is damaged and you will have to restore the file system first.

It seems that some function of automatic detection of partitions on external hard drives does not work.

How can the problem be solved?

First check if the service is running Virtual Disk (the service is called Virtual disk ). You can check the status of a service through the Service Management Console ( services.msc).

or from command line:

Sc query vds

SERVICE_NAME: vds
TYPE: 10 WIN32_OWN_PROCESS
STATE: 1 STOPPED
WIN32_EXIT_CODE: 0 (0x0)
SERVICE_EXIT_CODE: 0 (0x0)
CHECKPOINT: 0x0
WAIT_HINT: 0x0

If the service is stopped, start it from the graphical snap-in (Start button) or like this:

Net start vds

Advice... In some cases, for correct work services Virtual Disk you have to change the type of its startup to Automatic (see).

Check if the problem persists. If enabling the service Virtual disk did not help, check if the function of automatic mounting of new volumes is enabled.

Note... When the automount function is enabled, Windows automatically mounts the file systems of new disks to be connected to the system and assigns drive letters to partitions itself. If automount is disabled, Windows detects new drives, but does not produce them automatic installation and does not assign drive letters to new volumes.

Open a command prompt window (with administrator rights) and run the commands:

Diskpart

As part of diskpart, check if automatic mounting is enabled for new volumes:

DISKPART\u003e automount

Automatic mounting of new volumes disabled.
As we can see, autowiring is disabled. Let's turn it on

DISKPART\u003e automount enable

Automatic mounting of new volumes enabled.
Automatic mounting of new volumes is enabled.

Finish working with diskpart

DISKPART\u003e exit

Leaving DiskPart ...

Note... By the way, the automount function is also responsible for ensuring that the system remembers the drive letter assigned to the drive. Due to this, the next uSB connection drive, the partitions on the external drive will be assigned the same letters as in the previous connection (of course, if these letters are not occupied). To clear saved associations, you need to use the command automount scrub.

Restart your computer and check if letters are assigned external drives.

Check if the partition is not set to USB disk the attributes are hidden and will not assign a drive letter. At the Diskpart command prompt, run:

After that, this section on the flash drive should be automatically assigned a drive letter on any computer.

Also keep in mind that if there are multiple partitions on the USB stick, then Windows will only see the first partition. The ability to create appeared only in Windows 10 1703 (before that, in order for the second and subsequent partitions on the flash drive to be available in Windows, you had to use a trick forcing).

If your flash drive does not appear in the Disk Management Console, try using a different one USB port, cable. Try connecting the USB flash drive directly to the computer (without a USB hub), check if the power is turned on on it, and if it is detected on other computers.

Welcome! This blog is about the Internet and computers, or rather it was dedicated to them.

Probably, it is immediately clear that no new articles have appeared on the site for many years. Yes, that's the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others who wrote at the time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, then of those blogs that were created at the same time as mine, most have already disappeared into eternity. And I just didn't have enough time to blog. So yes, it is not updated anymore. Although once we with this site won the competition "Blog of Runet 2011".

I even had an idea to delete all this, but then I reviewed the old materials, and realized that they can still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will receive appropriate notes), but the site, for example, can be useful for beginners - here you can read about basic concepts Internet, learn how to configure the Internet, Windows, or even decide to switch to Linux. So look at the rubrics and choose the one that's right for you.

And yet, I hope this is more than just a blog, but a real guide to the Internet. The site can be viewed in the directory mode, where all available articles are structured by category. And who knows, maybe one day new high-quality articles will start appearing here.

Picodi.ru is a discount portal from International Coupons, a Polish expert in the field of savings and cheap shopping. Poles are considered one of the most economical nations in the world, so it is not surprising that this type of project grew out of the Polish startup kodyrabatowe.pl. How can this portal be useful to an ordinary Internet user in Russia?

Modern android phones are more than phones. You get used to typing installed programs, to your call and text message history, photo collection and much more. But time goes by, and the device that suits you completely starts to slow down, glitch, or simply loses its presentable appearance due to chips on the case or scratches on the screen. The question arises of choosing a new phone and changing android phone... And if we now bypass the question of choice, then "moving" to new phone remains a serious problem - you absolutely do not want to start all the data from scratch. This is what we'll talk about today.

Most of the readers of this blog, most likely, have never encountered version control systems and will not come across any in the near future. It's a pity. This extremely convenient invention is widely used by programmers, but, in my opinion, it could be very useful for those who actively work with texts. But, probably, now there is not a single version control system that would be easy to start using for "office" ( Microsoft Office) work. Nevertheless, I think that the material presented in the article may be interesting for all readers.

If you have thought about how to watch movies on the network from your TV and go online, this article is for you. No, I know that some TVs already have Smart TV functionality, but I have never seen it work properly. Apparently, therefore, recently the Google corporation demonstrated an absolutely stunning device that immediately became a sensation. It is about the Chromecast media streamer (Chromecast), a more advanced and affordable version of last year's disastrous Nexus Q.

Dongle Chromcast, which is no more than 2 inches in size, plugs into the port HDMI TV and allows you to enjoy watching streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on the operating platform iOS, Windows, Android or Mac OS.

This article is about the device system memory android, problems that may arise due to its lack and ways to solve them. I myself recently came across the fact that my android phone began to regularly give out messages about the lack of memory when trying to install an application. Which was very strange for me, given that according to the description on the market there should have been about 16GB, and I also increased this volume with an additional memory card. However, there was a problem, and I had to tinker a lot before I found the right solution, which did not require root access or a full restoration of the phone to its factory state.

While working with personal computer it may be necessary to modify, add or remove partitions of the hard disk.

If during the initial windows installation 7 the creation of sections takes place in an interactive mode and is intuitive, then making changes to the created sections requires a certain skill.

Due to the lack of any experience in these matters, the user may incorrectly perform the necessary actions, which will subsequently lead to a complete loss of data or even to the failure of the hard disk. To facilitate the process of creating and modifying disk partitions, the Disk Management utility will help.

Disk Management utility and its functions

The Disk Management utility is a tool for performing various operations with hard disks and their partitions.

With its help you can:

create, delete, merge volumes on the disk;
shrink volumes;
format volumes;
assign letters to volumes;
add volumes without rebooting;
manage local and remote disks online.

Opening Disk Management

There are several ways to launch the program.

Through the start menu

Click on the "Start" menu and right-click on "Computer". We choose "Management".
Right-click on "Computer" and select "Management"
In the "Computer Management" window that opens, click on "Disk Management".
Selecting "Disk Management"
The Disk Management window opens.
Disk Management Utility Window

Press the Win and R keys at the same time.
Press the Win and R keys
In the "Run" dialog box that opens, enter the command "diskmgmt.msc" and click "OK".
Enter the command "diskmgmt.msc" and click "OK"

Click on the "Start" menu, select "Control Panel".
Click "Control Panel"
In the search box, enter "administration" and click on the "Administration" section that appears.
Click on the "Administration" section
In the list, select "Computer Management".
Choose "Computer Management"
In the "Computer Management" window that opens, click on "Disk Management".
Click on "Disk Management"

There are situations when the Disk Management console does not open, or it opens, but the console window is blank, and the warning "Failed to connect to the Logical Disk Manager service" appears.

There are various reasons for this problem. To eliminate their influence on the disk management process, you must do the following:

Conduct antivirus scan. Running antivirus software it is recommended to do it from an optical disc or from a protected flash drive. After checking, open "Quarantine" of the antivirus. If the dmdskmgr.dll library is in the Quarantine, then return it to its place.
Run the command Rundll32 setupapi, InstallHinfSection DefaultInstall 132% windir% \\ inf \\ dmreg.inf through the Start menu and the Run window.
Go to "Control Panel" - "Administrative Tools" - "Services" and make sure that "Logical Disk Manager" and "Logical Disk Manager Administrative Service" are running. If they are stopped, then enable them.
Enter the Basic Input / Output System (BIOS) menu. To do this, while turning on the computer, press Del, F2 or Esc (the choice of key depends on the manufacturer of the computer). If in launch pad there is no information about the connected HDD, then check the connecting cables at the points of connection to the drive.

The very first hard drives, first created by IBM in 1973, contained 30 cylinders, each of which was divided into 30 tracks.

By analogy with automatic rifles using the .30–30 Winchester cartridge, such discs were called "Winchesters".

Over time, in colloquial speech, the word "Winchester" was transformed into "screw".

Most "hard drives" are sold already prepared for Windows installation, ie, the main partition has already been created on them.

The rest of the operations are carried out during the installation of the system. Installation is carried out from a bootable optical disc or USB device.

At one of the installation stages, a window will appear prompting you to select a space for installing the system.

Choosing a space for installing the system

If the "hard drive" before going on sale was not prepared for immediate installation of the system, then the user will have to do all the operations. This requires a bootable optical disc or USB stick.

Before installation, we configure the BIOS (basic input-output system) to boot from a DVD or USB drive:

At the initial stage of booting the computer, press the F11, F12 or Esc key (the choice of the key depends on the computer manufacturer) to call the Boot Menu.
In the menu that appears, select the drive from which you need to boot the system.
In the menu that appears, select the drive from which you need to boot the system

When forming a partition on a "hard drive", everything is used free space, and additional partitions are created after installing Windows 7.

If possible, it is better to use booting Windows PE in which the acronis software Disk Director or Partition Magic. These utilities are designed to manage partitions on a hard drive.

Windows Preinstallation Environment (Windows PE) is used to prepare a computer for installing Windows. It is built-in to other system installation and recovery tools and is not intended to be used as a primary operating system.

In the absence of such boot disklike Windows PE you can:

Boot from a disk containing the Volkov Commander shell.
Find fdisk.exe
In this shell, run system utility fdisk.exe to create primary and secondary partitions.
Create main and additional sections

The created logical drives must be formatted using the format.com utility. Now you can proceed to install Windows 7.

Management of logical drives "hard drive"

You can manage hard drive partitions through the context menu of each of them. They present a set of commands required to operate.

Compressing a section

The command to compress the logical disk is specified in context menu.

Right-click on the section and select "Shrink Volume" in the context menu that opens.
In the context menu, select "Shrink Volume"
Enter the size of the compressible space in megabytes and click the "Compress" button.
Enter the size of the compressible space and click the "Compress" button

Creating a section

The new partition is created in a free area of \u200b\u200bthe hard drive, which does not yet belong to the formatted volume. At the bottom of the Disk Management console, this space is highlighted in bright green, and in the legend line is indicated as “Free”.

When the partition has been compressed, right-click on the unallocated space and select Create Simple Volume from the context menu.
Right-click on the unallocated space and select "Create Simple Volume" in the context menu
The "Simple Volume Wizard" will start.
After starting the "Simple Volume Wizard", click "Next"
We indicate the size of the new volume.
Specify the size of the new volume
We assign a letter (letter) to the disk.
Assigning a drive letter (letter)
Determine the file system, cluster size and volume label.
We are formatting the section.
Formatting the section
In the last window, click on the "Finish" button and create a new logical disk.
Click on the "Finish" button

Formatting a partition

In the context menu, select the "Format" command.
We select the command "Format ..."
You can set a word for a volume label, choose a file system to reformat. It is recommended to leave the default cluster size. Click on "OK".
Select the volume label, NTFS file system and click on "OK"

After reformatting, the volume is ready for use.

Changing the letter of a section

In the context menu, select the item "Change drive letter or path to drive".
Select the item "Change the drive letter or path to the drive"
In the window that opens, click on the "Change" button, change the letter and click on "OK".
Change the letter of the section and click on "OK"

Merging sections

When it becomes necessary to reduce the number of logical drives, the two are merged into one common logical drive. Before merging, the necessary information from the removed logical disk is copied to another disk or to removable media.

To combine one drive with another:

Select the volume you want to attach and call the context menu. Click on "Delete volume".
Select the volume, call the context menu and click on "Delete volume"
A message will appear in the opened window that all data on the volume will be deleted. Confirm deletion.
We confirm deletion
In place of the deleted volume, a partition with the "Free" status will appear. Select it and select "Delete section" in the context menu.
To attach an empty volume to the desired logical disk, right-click on the section to which it will be attached empty section, and in the context menu select "Expand volume".
Right-click on the section to which the empty partition will be attached, and in the context menu select "Expand Volume"
In the next window, mark the empty volume and attach to the main volume.
Mark the empty volume and attach to the main volume

After merging is complete, restart Windows 7 to avoid errors and loss of information.

Disk management software

For managing drives other than standard utility "Disk Management", there are several programs. They are widely used due to their clear and user-friendly interface. These programs include:

Acronis Disk Director is a program that provides management logical drives and is responsible for maintaining "hard drives"; Provides management of logical disks and is responsible for maintaining "hard drives"
Partition Magic is a program with fewer features compared to Acronis Disk Director. This utility is outdated and not supported by most manufacturers, but is included in the package software on old boot disks; This utility is outdated and not supported by most manufacturers, but is included with the software on older boot disks
AOMEI Partition Assistant - a lesser known program for working with partitions "hard drive". One of the advantages of this program is the ability to transform the main boot record from MBR to GPT without loss of information. This feature can come in handy when migrating from Windows 7 to Windows 8, and is essential for users working with these systems. One of the advantages of this program is the ability to convert the Master Boot Record from MBR format to GPT format without losing information

In addition to these utilities, on the Internet, you can find other developments designed to work with hard disk partitions.

Despite all the variety of utilities for working with hard drives, it is better to opt for one, study it and use it in your work, since improper use of programs can lead to the deletion of important data accumulated over many years of work. Recovering lost information will take a lot of time and effort, but it may not lead to the desired result.

Open msc windows snap-in via command line

msc windows snap

Good afternoon, dear readers and blog subscribers, today we will talk about how to open msc windows snap-ins via the command line, what you might need it for and how it will help in the daily practice of a system administrator.

Believe the knowledge gained in this article, in the future you will be able to save a huge amount of time and nerve cells, not to mention the opportunity to show off nerdy knowledge in front of your colleagues, simply if you actively use linux system and you know the basic commands in the console, then you will be interested in these too. Always, if possible, strive to study, in addition to the GUI interfaces, also alternative methods of setting, since when windows setup Server, increasingly choose core mode with a minimalist interface.

What is msc snap

And so msc in Windows stands for Microsoft System Console, it is even simpler these are windows or, as they are also called snap-ins, to control certain functions of the operating system. Earlier, I already introduced you to the method of creating a convenient mmc snap-in, in which we added everything we need system administrator for day-to-day administration.

And you probably ask, what does the command line and all that have to do with it, but what does it have to do with it.

Imagine a situation, you have an Active Directory domain in your organization, ordinary users do not have local administrator rights on their workstations, everything goes and works like a clock, a situation happens that, for example, you need to change some settings for a user, and you need to do it now , so look for these settings in group politics no time. What to do to go under yourself is not an option, since you need to make changes in another user profile, and how to open, for example, the Computer Management or System snap-in.

This is where knowing the name of msc windows snap-ins and the command line will help us.

All you need to do is open a command prompt as administrator and enter the desired name for the msc snap-in. Below is a list. As you can see by opening the command line cmd.

exe, for example, I entered the value that opens the control panel with system administrator rights.
