grep wd from dmesg shows :

wd0 at atabus0 drive 0
wd0: <Hitachi HDS721010DLE630>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 931 GB, 1938021 cyl, 16 head, 63 sec, 512 bytes/sect x 1953525168 
sectors
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd1 at atabus0 drive 1
wd1: <Hitachi HDS721010DLE630>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 931 GB, 1938021 cyl, 16 head, 63 sec, 512 bytes/sect x 1953525168 
sectors
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)


I have an older NetBSD box which shows this in its dmesg output :

wd0 at atabus1 drive 0: <ST3320613AS>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 298 GB, 620178 cyl, 16 head, 63 sec, 512 bytes/sect x 625140335 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd1 at atabus1 drive 1: <ST3320613AS>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 298 GB, 620181 cyl, 16 head, 63 sec, 512 bytes/sect x 625142448 sectors
wd1: 32-bit data port
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd0(piixide0:1:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using 
DMA)
wd1(piixide0:1:1): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using 
DMA)


Missing from the new box is the two lines saying that wdN is using PIO 
mode 4, ultra-DMS mode 6
Is that maybe the issue?

Something in the BIOS?
