In using Partition magic, trying to create 3- 40G drives out of the total 120G, during resizing the first 80G I'm getting error 1531 too few clusters.  Any suggestions?  There's only 23G data on this 80G so I figured 40G would be plenty of room.  What am I missing?  Thanks for any help.

Thanks for replying, Ghost4....they suggested CHKDSK/F which I  tried...now I get error 983: too many errors, and their solution for that is....you guessed it, run CHKDSK again.....what gets me is that this hard drive is only about 4 months old and I haven't had any trouble with it...so why are there errors?  Again, I'm a newbie so I appreciate ANY info, even if you think it's too 'elementary'...thanks again...
