I have a 40gig Samsung HD on an ECS P4VXASD mobo. I noticed that when I run SANDRA, it shows the drive running at UDMA 2..I checked the drive's specs and it can go up to ATA 100, so why is it only on UDMA 2 instead of 4 or 5? Could that be due to the IDE cable or do I need new drivers? What drivers would I need....mobo, bios, (no setting in Bios to change UDMA modes...

Any ideas?

The HDD being forced into UDMA2 could be caused by a couple of things. Using a 40 conductor IDE cable will limit the drive to mode 2. If not and you are using XP, check the event viewer for hardware errors on the IDE controllers, since XP can ramp the modes down in the event of repeated CRC or timing errors. Make sure that the motherboard drivers are updated as well.
