This error usually comes from Windows and may happen due to various reasons:
Windows uses a transfer mode that the hardware device cannot.
OS is trying to get more IOPS from the HDD than the drive can provide.
The drive is damaged, e.g., there is a bad spot on the disk.
Unfortunately, there are not so many things we can do about it. However, you can try the following changes:
Decrease thread count to 2 in Tools > Options > Advanced.
Don't run the backup in high load hours (non-working hours are recommended).
In case the disk is External USB-drive, you can try to reinstall the Disk driver from Windows side: Go to Device Manager, right-click your device's name, and select Uninstall. Keep your device connected. Restart the PC and Windows will attempt to reinstall the driver.
If all of the measures above are taken, and the issue persists, it points to a hardware problem. As general suggestions, I can advise:
Check the S.M.A.R.T. status of the physical drive that is backed up, for example, with this tool - http://hdtune.com/
Check that drive's partition file system integrity by executing in elevated CMD: chkdsk E: /f
You might need to schedule a check on the next run if it cannot be performed immediately.
