Weird HDD test results

[NoamRaz]

Hello,
I have gotten very weird results of the Sisoft Sandra HDD test. I have tested three logic devices C:, D:, and E:, where actually they are two HDD. Two (C: and E of them showed similar results ~20000kB/s, while the third one (D showed ~37000kB/s. The problem is that C: and D: devices are actualy the same HDD, therefore I don't realize why their test results are so different. I can't attribute the difference to the fact that they utilize different file system, namely, C: is NTFS and D:and E: is FAT32. Please advise. Here is my system configuration:

Athlon XP 2000+
KT4V MS6712 motherboard
256 Mb DDR 333 Samsung
WD 40 Gb IDE master
IBM 60 Gb IDE slave
Samsung SW 248F master
Pioneer DVD-120 slave
PSU 400W
Windows XP Home Edition


Best Regards,

Are you sure your D: drive is the second Maxtor partition and not the IBM drive?

Soulprovider, Thanks for replay.
Logical disk D: is the second partition of the hard disk, which is IBM HDD IC35L060AVV207-0 60Gb. The second HDD is WD400JB of Western Digital with 8Mb buffer. By the way, the low test rate, namely, ~20000Kb/s of WD drive which is supposed to be much better, is my second problem. However, it might be that there is only one root cause of the low performance of the two logical devices (C: and E as well as possible discrepancy of the performances of logical devices, which are the same HDD.

No replays. So, I will answer by myself. I have solved the problem of disk E, which is WD400JB. Defragmentation of this disk allowed to improve its Sisoft Sandra test performance to ~31000KB/s. Defragmentation of disk C, which is the first partition of IBM IC35L060 HDD, allowed to improve its test performance to ~25000Kb/s. However, this performance remains much slower vs. ~37000KB/s of the second partition of the same HDD. Perhaps, there is another cause of this performance degradation.
