I would replace the "bad" drive immediately. It's possible that it has
bad blocks, and the RAID controller was able to identify and flag them
before it reconstituted it. Whatever the case, you probably ought to
replace it just in case.

So, in addition to my issues with my external drive, my server went
down last night for another reason. It had something to do with one of
the drives (in RAID). It appears that the HD failed, but the strange
thing is that it is back up and running now. The reason that I
discovered something was wrong is because the server went down and
then would not come back up. This was because it could not find any
logical drives. Inside the RAID utility, it reiterated that there were
no logical drives. My initial reaction was "oh, crap, they have both
failed." We tried pulling one out at a time though and rebooting to
narrow our conclusion, something that was a good idea. Turns out that
only one of them was bad. This is where it gets weird though. It kind
of seems like it might not have been a drive at all; I am wondering if
it was the RAID controller. I say this because the point of RAID is so
that one of the drives can fail and things will keep going. If one of
the drives was still good then the controller should have still said
that an array at least existed. I rebooted with the one good drive and
everything came up hunky-dory. I rebooted a few other times checking
and testing things and then had the idea to try putting the "bad"
drive back in. Interestingly, when I did, the RAID picked it up and
started "reconstituting" it. Now, it says that everything is peaches.
I can't ignore that something bad happened though. What are people's
impressions or thoughts? Sound like perhaps the controller just had a
heart attack and perhaps there was never anything wrong with the drive
at all? Perhaps the "bad" drive really did freak out but not to the
point of failing and after having the RAID rebuild it, it's okay for
another go? Is there a way to test if you controller is on the fritz?
I think I would be wise to order a backup drive. Any other suggestions?
