I have a WD 160 GB 7200 rpm hd on primary IDE channel set as master, its the only thing on that channel. an optical disk is on secondary ide channel.
looking in device manager, under ide ata/atpi controllers under primary ide channel advanced properties the transfer mode for both devices is set to 'DMA if available' but the primary HD is using ultra dma mode 2 as the 'current transfer mode'.
I have reinstalled win xp a bunch of times now, set jumpers on that hard drive to master, cs, slave etc and it simply won't run at its proper faster dma mode 5 ata100/133 speed.
looking in event viewer I get the following error which on the MS web site says it most likely related to a cable problem even though the actual error message says 'controller error'. It's a fairly new cable, but i believe in the past ive tried a few different ata100/133 cables on that same hard drive with no better results.
Event Type: Error
Event Source: Disk
Event Category: None
Event ID: 11
Time: 3:03:34 PM
The driver detected a controller error on \Device\Harddisk2\D.

what the hell is going on, why can't i get this hd to use a faster IO mode? Thanks
