Hi. I have had my computer set up for some months now and noticed that my HD performance seems to be so lacking. I got Sisoft Sandra and ran the HD benchmark test and scored a meager 4700kb when 10 and 30 gib ATA66 HD's were scoring around 10,000-15,000 kb. I know something is wrong but I can't islote the problem. I updated to the latest via driver, I have check the bios and jumpers and everything seems correct. I am going to replace the IDE cable incase it is not an ATA100 cable (my only guess so far) but I just can't seem to figure it out, system specs -

Atholan XP 1600+ TB at 1800+
256 megs generic PC133
Maxtor 5400rpm ATA100 40 gig HD
Geforce4 TI4200 Special edition 128 meg
SB live! value
2 generic lan cards

I ran though all the settings I could think of, DMA is on at UltraDMA mode 5. Everything looks good in the bios. I guess I will try resetting to all default and running the benchmark agian. Something is def. off. I also have copy and pasted my Sisoft results. Hopefully someone can help me and give me some ideas.

SiSoftware Sandra

Performance Tips
Notice 5008 : To change benchmarks, click Options.
Notice 5004 : Synthetic benchmark. May not tally with 'real-life' performance.
Notice 5006 : Only compare the results with ones obtained using the same version!
Tip 5203 : Bypass cache to measure controller/disk performance.
Tip 2 : Double-click tip or press Enter while a tip is selected for more information about the tip.

Right now in comparrison it is slower then an ATA33 4.2k rpm 6.4 gb hard disk. I just can't find the problem.
