One of my client PC's blue screened overnight and wouldn't boot.
The system post was hanging also for about 10 seconds trying to find the drive. System would not boot afterwards saying "inaccessible boot device".
The BIOS also had some trouble finding the drive half the time.
I tried slapping the drive, hitting it on the floor, freezing it for 1 hour and nothing. But the drive is still spinning.
After connecting that drive to another system (xp), "drive is corrupted" on eventmgr, the XP system even had a hard time booting with the failing secondary and of course I got the "drive is not formatted" error. I ran chkdsk /R on it, it unmounted the drive (then system started responding normally), after a few tries and a few thousand "File record segment xxxxx is unreadable" errors which took about 2 hours it was done. Chkdsk was finished, it reported fixing a bunch of stuff (I wish I had copied the output) the drive was fully accessible. Even after a few hours there isn't a hitch with the drive anymore.
How can this be? This surely seemed like a physical problem with the drive. I thought chkdsk only fixes ntfs links , bad sectors, etc.
This was on a 250gig Seagate . I don't have the exact model handy.
