Larian Studios Forums General Chat Defrag doesn't work. Why is that?

I need help please.

Some time ago, suddenly, my Win XP defragmenter started to show - Unable to initialize.

Yesterday I have installed program called Deskeeper. It works analogically to defrag. The problem is that it doesn't work either, and shows the same text. Unable to initialize.

I have two different HDD's. Both particioned - one into three, another into two parts (1 FAT all others are NTFS).

I am trying to do error-checking on all drives but, main drive can do CHKDSK on restart only. Second drive checks for errors in windows.
But still even after error-checking nothing really happends.

Please advise.
