Hi,
I am also seeing this problem...
If I run df.exe c: /ts
it says:
Building File List (96%)
Building File List (97%)
Building File List (98%)
Building File List (99%)
Building File List (100%)
Building File List Complete
3% of the drive is fragmented
Defragmenting drive C:
Defrag Started
Defragmenting (0%)
Defrag Aborted
Finish
If I run df.exe c: /ts /QD
it doesn't crash, but it seems to get stuck at 0% for a long time (theres only 3% fragmentation)
I gave up after a few minutes and ran it as df.exe c: /QD
I waited for a bit, in that time I registered on this forum, clicked through the email to confirm, logged on and wrote this message, and has *just* moved onto 1%.
I ctrl-c to kill it after it reached 2% (about 10 seconds later) and started it on /ts /QD again at 2:13pm.
It made it to 1% at 2:17pm and finished the quick defrag at 2:21pm
I ran df.exe c: /ts it said 3% of the drive is fragmented (still), and then aborted.
