Here's the first one.  I have a clue on this one.

I got Milton's hardware notes just a few minutes from osu, and if I'm
reading correctly, I may have faulty power on this one.

The next group is more interesting...

HDERR ST:51 EF:40 CL:3E CH:3 SN:27 SC:1 SDH:21 DMACNT:FFFF DCRREG:99 MCRREG:8700 Fri Apr  6 21:06:02 1990

WD2010 ST=/Sekg/Err/ EF=/CRC/ cy=830. sc=39. hd=9. dr#=0. MCR2:0x1 Fri Apr  6 21:06:04 1990
------------------------
Did you notice sector number 39 up there?  I did!
I'm fuzed and condazed on this one.
It sez 'EF:40' so that means CRC error, right?  What is it doing with 'SN:27' ?
How could it even find the sector?  Maybe it's masking off a bit, using  :17.
But that's still invalid.  OK maybe it's masking with '0x0f', but then it can't
read sector 16, which isn't used anyway.  :-(

But WAIT!  There's more...

I'm going to run diags, etc.
If anyone has any other ideas, please let me know.

Thanx!
