Windows 7: Event ID 7 The device has a bad block

17 Nov 2019   #11

Windows 7 HP 64

There are two types of disk failures: Logical and physical.
Check disk (chkdsk c: /f) looks for logical problems on a partition (C:) and fix them. It also can find find bad clusters, bad blocks, bad sectors etc but it can't correct them as they are surface (physical) problems on a dying disk that can't be fixed by any tool.

Replace the drive ASAP. Replace it with a SSD. They cost almost as much as a first line HDD.

"...bad clusters, bad blocks, bad sectors etc..." GRC SpinRite purports to either fix a bad sector or have HDD mobo mark it forever off-limits to any/all OS. HardDisk Sentinel and a few other similar utilities purport to be able to "tell" HDD mobo to mark a bad sector as off-limits.

Run SeaTools on your drive!
chkdsk is not designed to test your drive for failure, only to correct/replace system files (dlls) etc.
