slow IBM 30 gig

[smoorman]

I have a KG7 raid board. In sandra I can only score 12000 for HD tests. This is half what it should be. I have the drive connected to IDE 1 as a master using the ata100 cable. It shows up in device mgr. as udma5. Anyone know whats up? Thanks in advance.

What's up:D
Do you have DMA enabled in the device manager in Windows?

[smoorman]

Yes it is and like I said the drive shows up at udma5.

[RainMaQer]

Are you using drivers for it?

[turd]

UDMA 5 is what it should say (UDMA 100 \ATA 100 \ UltraDMA 100)

UDMA 3: burst data transfer rates up to 33 MB/s
UDMA 4: 66
UDMA 5: 100

I have heard that the 80 wire cables must have the master on the end (black connector)and any slave in the middle (gray) for proper performance but, i have never tested this myself, could be related?

Also, what OS are u running?

[smoorman]

I'm runnig XPpro. Do I need drivers?

u know i dont Xp, had it and went back to 2k, am going to put down some VMWARE and run xp again very soon, and just got abeta of the XP server(.net), so will do this by next week, but

i dont think u should need any extra drivers, just check your device manager -click on that disk and check the properties, it should tell u about the drivers that Xp put in for u, u can reinstal them from that window if u want

also check your bios andmake sure that you have the udma detection enabled as auto for all ide devices

u could try and rightr click my computer
click on manage/device manager
expand IDE ATA/ATPI controller
click on primary IDE Channel/Advanced settings
and for transfer mode make sure it says "DMA IF AVAILABLE"

if it already says this fine below that it should say Ultra....

IF NOT

make it say "DMA IF....." and reboot
