The Device Hard Disk has a bad block

[DanCooley]

When using this disk - WD Elements external hard disk, I get the event viewer error many times: The device \Device\Harddisk6\DR7 has a bad block

When I run chkdsk /f /r on this disk it cannot find nor repair any errors

When I run AOMEI surface test it reports several bad sectors.

Hook into Windows 10

Very quickly it says we have scanned this disk and it has no errors, would you like to scan anyway. When I say yes, it scans quickly and says no errors.

Back to Windows 7, disk error again.

What should I do?

The only advice I would have to give is to run chkdsk /r and that is something you have already done.

Well, don't depend on the disk now as there is a possibility that it could fail.

Perhaps you could connect it to Windows 10, backup your data and hard format it and see.

CHKDSK is a built-in utility in Windows that can be used to scan and fix your hard drive error caused by bad sectors, improper or sudden shutdowns, corrupted software, and Meta data corruption. CHKDSK scan is the most common way to fix “the Device \Device\Harddisk0\DR0 has a Bad Block” issue.
