External SCSI Disk Failed?

Gurus,

I see messages like follows all the time, but hoping that maybe my case is
different and this is not hopeless.

We had a perfectly working very old disk attached to an E450 via a SCSI
cable. It was one of those old single disk scsi enclosures, I don't even
think it was made by Sun. The disk was meant to hold temporary data, but
unfortunately temporarily some very important data was put on it
(temporarily, but never moved back). Today after something dropped on it,
while the cover was open, it stopped working. I hoping that it's not the
disk itself that failed, but a bunch of electrical parts surrounding it.
So I moved the physical disk to a similar casing, but seeing the same
errors (notice, it's the same disk, I tried attaching it to different SCSI
ports at various times). Should I stop trying to bring it back to life? Is
there are a sure way to tell?

Thanks.
