Question:
How come I can't open some directories on my C:\ drive? I get the error
"c:\directoryname is not accessible. Access is denied."
Answer:
I have had the same problem on a number of occasions, particularly with a bad SCSI card
I once had. I strongly suggest that, from the command line, you run:
CHKDSK C: /F /R
The /F fixes disk errors, and the /R locates bad sectors and recovers readable information.
If this problem continues, you might need to replace the HD and/or the controller. There
are other reasons that can give you the above error, but in my experience, this is the most
common.
