Go to USBSTOR
  • Enter 3 in the Value data column and click OK.
Enter Value data and Press OK
  • Once done, close the registry editor and check if you can use the DiskPart utility without any interruptions.

Error 2: DiskPart has encountered an error the request could not be performed because of an I/O device error

This error usually occurs when Windows faces difficulty performing an input/output action when trying to access a drive. Another reason could be bad sectors on the hard drive or a corrupted drive partition table.

Solutions

A. Update Disk Driver

Sometimes, a corrupt or outdated device driver may cause this DiskPart error. To get rid of this, you may try updating the disk driver by following given steps:

  • Open Device Manager and then navigate to the device category.
  • Expand the device category, right-click on the driver, and click Update driver.
Click on Update the Driver after pressing the right click on Microsoft AC Adapter

B. Run CHKDSK Command

CHKDSK command, when run with attributes /f and /r, fixes corruption (if any) on the hard drive. Also, it scans and marks down the bad sectors on the drive. Although, while scanning and marking the bad sectors on the drive, it prevents Windows from reading and storing data from those bad sectors, which result in data loss.

Note: Before you proceed with performing CHKDSK command, we’d suggest you take backup of your data. If you have no backup, you may recover it using a powerful data recovery software.

 
  • Run Command Prompt as an administrator and type CHKDSK /f/r/d: and press Enter. (Replace d: with your drive letter.)
chkdsk command
  • Wait for the process to complete. Once done, close the Command Prompt window and see if you can use the DiskPart utility.

C. Fix Damaged or Corrupt Hard Drive Partition Table by Rebuilding MBR Boot

As discussed above, another reason for ‘DiskPart has encountered an error’ could be a corrupted drive partition table. You may try fixing it by rebuilding MBR boot. Follow these steps:

  • Type cmd to open Command Prompt and type the following commands one after another and press Enter.

Bootrec/fixmbr

Bootrec/fixboot

enter BOOTREC.FIXMBR Command
  • Let the process end. Once done, close the Command Prompt window and reboot your system.

Error 3: DiskPart has encountered an error the request failed due to a fatal device hardware error

However, the primary reasons include hard drive corruption, registry file corruption, misconfigured files, cluttered disk, unsuccessful program installation, etc. The CRC (Cyclic Redundancy Check) error is quite a severe issue. You need to resolve this error immediately to avoid system failure and data loss. There are different types of CRC errors, such as:

  • Data Error (CRC) Error Message in Outlook
  • Drive Is Not Accessible Data Error (Cyclic Redundancy Check)
  • Cyclic Redundancy Check Error on an optical disc (CD, DVD, etc.)
