[comp.sys.amiga] Disk Drive faux pas.

jim@coplex.UUCP (Jim Sewell) (01/04/88)

I have a question regarding hardware repair.  I, er, uhem, a friend of mine,
yeah, that's who it was, plugged in my, er, his external drive with the power
to the computer on.  Yes, I know it was a stupid thing to do, but you know how
it goes on a bad day.  Anyway, I plugged in the drive and guess what?  It died.
I am assuming I power-surged something into the great land of charcoal and
molten plastic.  The drive would make some weird noises that reminded me of a
vacuum cleaner with a loose plug... you know, like it would start up and when
it got just shy of full whine it would die out again.  If anybody has done 
this before and knows from experience, or has not done it but knows what is 
most likely burned out, I would appreciate it very much.  I sure would hate to 
have to buy another drive because a $.39 capacitor is fried.

Engineering:  Capt'n, we are going ahead at warp 8, but our port engines are out
Captain    :  Result?
Engineering:  We be goin in circles, sir.
Captain    :  Not good.
Engineering:  It's even worse than that, I think we are catching up to ourselves

I have an even better question!  When the aforementioned problem occured I 
immediately thought, "Maybe it is a program confusing my Ami." So I rebooted 
from power off.  When this provided the same results, I repeated the whole cold
boot sequence.  Being desperate I did this 4 times with no better results.  This
morning, however, when I woke Amy up, the drive started clicking when Workbench
came up and upon being fed a disk worked like a charm!  Is my computer possessed
by some really bizarre form of a virus [ 8-) ] or what?  Any ideas?

When you turn off something like a computer, all of the power doesn't drain
out of the components right away.. By the time the next day came around, all
of the parts had time to release their charge.....

No.  Your computer has some "diginurds" in it.  Diginurds have been
described as demons playing billiards with the electrons in 
semi-conductor material.  There was an article about them in some 
technical journal over 10 years ago, but I don't remember it now.
