(note: this is probably a different issue than the recent SCSI reporting
bug)
I have two identical IDE drives in my system, and FreeBSD reports their
identical model numbers, but their sizes and geometries are reported
differently. The bug appears to be more serious than just reporting it,
as I can only use a third of the capacity of one of the drives. To better
explain, here is my "boot -v" output (cvsupped monday night, disks in
question are wd1 and wd2.)

Notice how the BIOS geometries are the same, the vendor and model tags are
the same, yet they are detected differently. Any ideas?
