[nagual 0]

when i try to defrag my d: it says 'Engine Connection lost' but i can defragment all my other partitions.

 

hd1 : c:\ and d:\

hd2 : g:\ and f:\

 

all defragment fine except d:\

 

any ideas ?

try disabling all backgroud processes, especially virus scanners when doing a defrag.

I was having the same "lost engine connection" trying to run defrag. I ran chkntfs and it fixed my prob. Thanks!

I have the same problem but Im not sure what to do with chkntfs, please advice!

Ive tried to just type 'chkntfs C:' but it just says C: isnt dirty.

What to do?
