I use windows 7 from the beginning, so the first time when I looked into the Windows 7 Disk Defragment program and I saw the Scheduled Defrag I supposed that it worked and I did not check if it worked good...
More and more months later I had some problems running programs/games/etc and I come back there and I saw in the bottom that Last Run wasn't updated at all... So 1 month ago I manually did a defrag an all the disks re-scheduled the automatic deframentation to 1PM (the computer is always on at that time)...
But it seems to me that it never do a defragmentation.... Look at the below image..
Is this normal to not have the last run updated?
UPDATE After 2 Month I looked again into disk Defrag... Here's some screenshots
The % of fragmentation on main and secondary disk is 6% and 5%, the Last Run is today becasue I started the analyze disk, but before that Last Run was the same as the System Reserved disk and the first screenshot (03/20/2012)
As you can see from the last screen, the scheduler never started...
Now I changed some conditions like remove the
start service only if idle for 3minutes
Hope this helps, otherwise any other guess?
