Chkdsk checks your disk for errors at a low level, requiring exclusive access to the disk to do so. “Chkdsk cannot run…” means it doesn’t have the exclusive access it needs.
hard drive error
It sounds like your hard drive is dead. You are going to have to dig deep to get the computer going again.
The answer to this is simple. If it’s only in one place… it’s not backed up!
A grinding noise and slow computer probably indicate the worse. Stop everything right now and back up!
If you’re backed up, this isn’t going to be a problem. Otherwise, there are only a few steps we can take to help us retrieve your data.
Hard drive failures happen. Everyone needs to realize that. You can probably guess my recommendation for staying safe.
If CHKDSK freezes when you run it, you may have a problem with your files or hard disk. But don’t blame CHKDSK for the problem.
Hard disk errors come from several different sources, and as a result there are several different approaches to resolving them.
