Poor disk IO performance

I have two maxtor drives: 60Gb and 120Gb. I took PCpitstop's full test and it informed me that my hard drive performance remains around 11mb/s. Though after i took it again, it went around 80mb/s. Also sometimes when i am moving huge chunck of information, appx. 2-4Gb, i sometimes get "Directory not empty" in the middle of action. Is my drive failing or is there something wrong with Windows XP? There are no spywares, viruses or such. I have very few background programs running. The result is pure disk IO performance. Anybody know what's wrong with it?
 
Are you running the disk drives as master and slave on the same channel? IF you are and you try and copy files that could cause a slowdown (but probably not what you are seeing). Make sure you have the write caching turned on in the device manager for each hard-drive as well. Are you running the disks on FAT32 or NTFS filesystem? Also, have you run a scandisk (and scheduled it for next reboot) and rebooted to see if scandisk picks up anything?
 
I have done most of the things you mentioned. Both drives are on different channel. 60Gb, the one has OS on, is running on master, 120Gb and Cd-Rom is running on slave. Caching is turned on, but pcpitstop report informs me that it is disabled. Both are running as NTFS for stability. I'll try to run scandisk and see what happens. Thanks. Though, funny thing is that pcpitstop report somtimes vary in great deal. Once, it said C: performed almost 80Mb, and the next test, the performance drop to 11mb/s.

By the way, both are running on U-ATA.
