ATA 100 IDE drive in WinXP using PIO?

I have been trying to understand what conditions would
create this issue. The hardware I am using is:

Asus A7V8X
Via 4 n 1 Drivers (latest vers 4.8)
Deskstar IC35L120AVV207-1 ATA100 IDE drive

Software:

Windows XP SP 1.A

I have the drive setup as Master on the Primary Channel
using an 80 Pin cable (Black connecter attached to the hd.
drive and blue connecter to the MB.

I have gone to VIAs site and researched the functionality
of the default IDE Filter driver that Win XP is using and
DMA5 is what transfer method it should be using for this
drive. The Bios is set accordingly as well. The drive is
brand new and so is the cable. Why the system is
downgrading the drive to PIO is beyond me. The only other
possible extenuating circumstance would be that I am also
using 2 Scsi drives and 1 as my Boot drive. Any help
would be appreciated.

Have you gone to IBM's website and downloaded their test software? There
may be an issues with the HD itself - enough people other than yourself have
had problems with certain IBM HDs.

Some actually started calling them "Deathstar" rather than "Deskstar"!

I have an older IBM HD ATA66 and it is detected OK under XP & XP SP1. It is
home to a W2K install right now with XP Pro on my RAID 0 array. XP sees it
as UDMA 4 which is correct.

You have gone into control panel and the ATA/ATAPI controlers and deleted
the controler that has the problem drive? On restart XP should re-detect
the HD. If it sees it as UDMA x at the point then downgrades to PIO there
is definitly a problem either with the cable, the drive or the controler -
cable is easiest to swap.

Good Luck,
Len
