If you receive The request could not be performed because of an I/O device error, Please rerun backup once issue is resolved message, while performing a backup on your Windows 8 computer, then this post may help you fix the issue.

Along with this message, you may also see accompanied, and error code 0x8007045D or 2147943517. These error codes represent ERROR_IO_DEVICE errors, which happen when there is a problem with the hard drive or disk from which you want to copy data.

The request could not be performed because of an I/O device error

If you face this error, here are a few suggestions you may want to try:

1] Start your Windows in Safe Mode. If this makes the problem go away and you are able to carry out your operation then it indicates that some third-party application may be interfering and causing the issue. Restart your computer in Clean Boot State and try to identify the offending item, and then disable or remove it.

2] Disable your antivirus software temporarily and see if it makes the problem go away. Some security software are known to cause these issues sometimes.

3] Check your hard disk for error. To do so, open an elevated command prompt windows, type the following and hit Enter:

Chkdsk /R D:

Here D is the drive label which is creating the problem. Replace this letter with your Drive’s letter. The /r ChkDsk command-line option identifies Bad Sectors and attempts recovery of information.

You may be asked if you want to Dismount the volume. Click No or N. You will then be asked if want chkdsk to run when system restarts next. Click Yes or Y.

Restart your Windows PC and let the ChkDsk run. Once the run is completed, you will be taken to your desktop.

See if this has made the problem go away.

If the backup still fails and you receive error 0x8007045D, then you might have to resize and shrink your volume by a couple of MBs to move the last cluster of the volume to a different area and then run ChkDsk again. This is because chkdsk.exe is not able to check and repair the last cluster on any volume – and if it is this cluster that has gone bad, then your backup may even fail at 99%.

Hope something helps.

    I am having Maxtor One Touch 500 GB external hdd. It gets detected when i open My Computer, but size is shown 0 Byte. If i open cmd and try to access the drive, it says I/O device error. If i try to run chkdsk it says Drive Busy. What to do?

    I think somehow your external hdd has been formatted wrong and is now full of blank data. I dont know if it can be repaired.

    I’m getting this error when attempting to initialize the disk via Disk Management. It isn’t even registering as a drive so chkdsk is not possible.
