Hello,

I'm seeing the same kind of problems with Western Digital drives :
ad0: 6149MB <WDC WD64AA> [13328/15/63] at ata0-master using UDMA33

I've switched to PIO4 access, but this is not the correct solution.

Is there something I could do to be sure of who is to blame (the disk firmware ?
the optimized IDE ata driver ?)

This is on a no-frills BX board with 4.1-Release :
FreeBSD 4.1-RELEASE #0: Tue Oct 17 08:34:26 CEST 2000
CPU: Pentium III/Pentium III Xeon/Celeron (448.05-MHz 686-class CPU)
pcib0: <Intel 82443BX (440 BX) host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
atapci0: <Intel PIIX4 ATA33 controller> port 0x1460-0x146f at device 7.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0

     TfH
