UDMA100 hdd running at 33

[gocrazyonafarm]

I have a highpoint hpt370 controller on my mobo and in winxp when i run HD Tach it gives scores of low 30s for the burst read on both my drives. One is a ata66 the other is ata100. This just happened after my last format. I used to get scores in the mid 60s (WD) to high 90s (IBM). Ive tried updating the bios of the hpt controller and installing new drivers. The rest of my specs or in the sig. Can somone please help me?

I was going to suggest you make sure you have an 80 connector cable, but if you had higher scores earlier I doubt that is it.

make sure that DMA is turned on in your OS
under control panel-system-hardware
since it was after a format id say this is the problem
also enable it on the other drive if you have one on the same channel as this can slow it down to the speed of the slower drive

Go to 3dspotlight.com
They have a WinXP tweak guide and it might have something in there about getting faster hard drive speeds. On Win2K ATA66 wasn't activated by default and I had to do a registry hack. It may be the same thing with XP but I would doubt it.

I do have the ata66/100 IDE cables and the drives are on seperate channels. I tried looking through the control panel and could not find any place to enable ata66/100 support.
