I have a laptop disk which seems to have developed a bad spot.  Can
anyone tell me how to reformat the drive?  Or is that not done on IDE
drives, and all I can do is partition around the bad spot?

The drive is

wd1 at pciide0 channel 1 drive 0: <TOSHIBA MK6409MAV>
wd1: drive supports 16-sector pio transfers, lba addressing
wd1: 6194 MB, 13424 cyl, 15 head, 63 sec, 512 bytes/sect x 12685680 sectors
wd1: 32-bits data port
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2

(this comes from my i386 desktop machine, to which the drive is
currently connected with a laptop<->desktop adapter).  I looked at
atactl, but even in -current it doesn't seem to have an option to
reformat a drive.
