I have a puzzling problem.=A0 I'm sure I just missed something simple, but =
I can't figure out what.

I added a drive to my system as Master on controller 2.=A0=A0 After turning=
 back on, I found I couldn't see that 80 GB drive on my system.=A0 I turned=
 it off, checked all settings, then turned it back on and verified that the=
 BIOS can see it - it's properly listed as an 80 GB Samsung as Master on 2.=
=A0 It sounds normal, looks normal and I can feel it spin up.

But I still don't see it on my system to mount it.=A0 I had just done this =
process with a 40 GB drive and it worked just fine, so I knew that I knew h=
ow to do it.=A0 That one showed up in dmesg and was easily mounted.=A0 For =
what it's worth, my Linux desktop, when I hook this drive up to an oddball =
USB-ATA adapter, acts exactly like it does with every OTHER drive I've pull=
ed out of a FreeBSD box - it sees it but hasn't a clue how to mount it prop=
erly.=A0 So I don't think the drive is a dud or anything.=A0 It was in use =
until a few weeks ago.

I will be verifying the drive is seen OK on another system shortly, but I'd=
 thought I'd throw this out there before then to see if anyone has any idea=
s,.

If someone would be so kind as to point me to some relevant help, I would g=
reatly appreciate it.=A0 Please reply to me in addition to the list: I rece=
ive the list in digest only.
