I moved a hard drive into a new system and im receiving a blue screen that says new hard is causing an error ... And to run chkdsk. Upon running chkdsk from the recovery screen its asking to dismount the volume ( assuming c: ) is it wise to say Y or N... I don't want to be locked out of the c: and not being able to remount of things go wrong.
It's safe, nothing bad will happen (Recovery itself should be running from X:). Unless the other disk is so damaged (platter surface or head assembly), that running chkdsk will only make it worse. I think you deliberately need to specify the volume on the disk, though. Otherwise why would it ask to dismount C:? What I mean is: chkdsk /R D:, if D: is the drive you've inserted into the system. Can be checked by diskpart - list volume.
