I just spent too much money on a nice Firewire enclosure and a 300gb HD for it. Plugged it in, formatted it, put a few files on it for testing.. everything was going well.

I right clicked on the drive and ejected it.. thinking a safe thing to do before powering down the drive..

When I power the drive back up, it doesn't mount. It does not show up in Disk Utility. It only shows up in the System Profiler as an "Unknown Device".

I've tried rebooting both the computer and drive and reconnecting everything 10 different ways. I just can't get it to work.

What the ??????

Why does Apple have an eject button for external drives if it's going to destroy everything?

Help!!

Ejecting it didn't cause the problems. You absolutely should eject it before turning it off.

As mduell states, ejecting is definitely the right thing to do and will never destroy data. Ejecting a disk unmounts it. Something else happened to that disk.

Discovered the solution for anyone interested...

I plugged the drive in with a USB cable. It mounted. I unplugged it and tried again with the firewire cable. Hey, it worked.

What a terrible, unintuitive answer.

Anyone know WHY this happened?

No, but I was having a problem with remounting and this script helps me out:
tell application "Finder"
if not (exists the disk "74") then
do shell script "diskutil mount `disktool -l | grep '74' |
sed 's/.*\\(disk[0-9s]*\\).*/\\1/'`"
end if
end tell
Replace 74 with the name of your disk.

I am curious as well. I have a problem that my firewire can be seen in Disk Utility, but won't mount (greyed), and I can't do any form of verifying through disk utility.

Any suggestions on what I should do ? I have tried this drive on 2 macs, and 1 PC.. still no visibility of it.

Hope someone can shet some light, in this unfortunate event. I got all my photos from 2006 :-(
