[fa.info-mac] problem with external disk drive

From: Martin J Mahoney <US.MJM%CU20B@COLUMBIA.ARPA>
I have been using my external drive for for a couple of weeks now
without any problem, however last night when i inserted a disk into it
I got the message that the directory was bad and should it try to rebuild
it.  Since I make ample use of the programmers switch i assumed it was my
fault, and said yes.  I then ejected the disk saying it coulding find something
and I should reinsert it but hold down the Command and option keys.

When I did this I the message that it couldn't read the disk and should
it initialize it. I said no.  I then ejected the disk in the internal drive
and inserted that into the external drive.  I got the same message that it 
couldn't read the disk and should it initialize it.  I knew that this disk was
good because I booted off of it.  I then inserted the first disk in the
internal drive where it was read fine.  

At this point I assumed that my external drive went bad.  I shut off the 
system waited a few miniutes then turned it back on.  The external drive then
work without any problems it was able to read in the disk that started
the whole thing.

Does any know what caused the problem? 
Has anyone else experienced a similar problem?
Do I have a flaky disk drive That i should get fixed before the warranty
runs out, or Problem with my Mac, or just some software bug.

Any help would be appreciated.
