I have a 500 GB WD external drive with 3 partitions on it. When I run a disk check, the computer shuts down. After that, I can't access the single partition I have important data on. When I try to check the disk, it displays the following message:
Disk check could not be performed because Windows cannot access disk
When I use the command line it gives some error message, and when I try to list the contents of the drive using the
dir command it shows me an error message about "cyclic redundancy". The other partitions work fine.
What should I do? At least I want to be able to back up my data.
