I dug up an old drive from storage:
wd0 at pciide0 channel 0 drive 0: <ST32122A>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 2014 MB, 4092 cyl, 16 head, 63 sec, 512 bytes/sect x 4124736 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA
data transfers)

So, I do:
# disklabel wd0 >wd0.label
# vi wd0.label (add a: partition..)
# disklabel -R -r wd0 wd0.label

and immediately:
wd0: no disk label
wd0: transfer error, downgrading to Ultra-DMA mode 1
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 1 (using DMA data
transfers)
wd0c: DMA error writing fsbn 0 of 0-15 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
wd0: transfer error, downgrading to DMA mode 2
wd0(pciide0:0:0): using PIO mode 4, DMA mode 2 (using DMA data transfers)
wd0c: DMA error writing fsbn 0 of 0-15 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
wd0: transfer error, downgrading to PIO mode 4
wd0(pciide0:0:0): using PIO mode 4
wd0c: DMA error writing fsbn 0 of 0-15 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
wd0: soft error (corrected)

After that it works, slowly (didn't pound on it though).

OK, I'll try to find a PC and I might as well try the HPT366 again.

Thanks,
