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 cardI 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. Thereare other reasons that can give you the above error, but in my experience, this is the mostcommon.
