Disk Manager is a Windows® system utility located in:
System and Security (this level is shown only if View by is Category)
For a hard drive problem, Disk Manager can help to quickly isolate the cause. If a drive is undetectable in Disk Manager, it may experience hardware failure. Data recovery may require an expert and may cost several hundred to a few thousand dollars. If the drive is displayed in Disk Manager, the problem is (not always but) most likely drive corruption. You can buy File Scavenger® and save data from a corrupted drive for $50.
Disk 0 is healthy.
Disk 1 is detectable but not accessible due to corruption.
Any other drive not detected in Disk Manager may experience hardware failure.
