Cannot run chkdsk Win XP Pro SP3 full updated.
Tried several times to run chkdsk via My Computer, C: properties, Tools, checked both, Restart.
"Windows cannot access volume"
Also tried RUN, cmd, chkdsk c:
Restart
"Windows cannot access volume"
Other progs:
AdAware, AVG 2013 (free)
Comodo Firewall
Malware Bytes
CC Cleaner
Keyscrambler
Disabled all Java on browsers
Could one of these progs be locking me out?
Any thoughts on repair or work arounds?
