CHKDSK is Windows built-in disk drive consistency check and repair tool.

CHKDSK is stuck after 48 hours. Is this a problem?

A CRC error and CHKDSK failure are signs of a hard drive that is on its way out. Recovery and replacement is the way to go.

Can I schedule CHKDSK to run before my automatic backup?

CHKDSK can be run with your Task Scheduler. The trick is getting it to run at the right time before your automatic backup.

Why doesn't CHKDSK work on my DVD drive?

CHKDSK will not run on DVDs because it is a hard disk repair and checking utility. DVDs are not hard drives.
