Two suggestions:
1) check if the disk controller chip is a WD2010 instead of a WD1010. This
is a 40-pin chip (mfd by Western Digital) and is located several inches
toward the left rear of the motherboard from the CPU. Your system "may"
require the "DRUN Patch" I posted back in December (assuming the HD itself
is OK and is spinning)
2) check if the HD is spinning when you power up. Many "older" HDs and most
HDs from a certain manufacturer (who shall remain nameless but whose name
begins with the letters "Seagate" :-) will exhibit a phenomenom termed
stiction (from static friction). Essentially, the heads are "glued" to the
platters in the park zone. Often the condition can be temporarily "fixed"
by twisting (using one's finger or the eraser end of a pencil) the shaft
on the head-stepper-motor a few degrees, then powering up the drive and
getting one's data off ASAP. I have over 3MB worth of data on this subject
already (which I started collecting after all 11 of my Seagate drives
(ST-251 and ST-157) encountered the problem only weeks after their warranty
periods expired).
And by twisting the spindle, I do NOT mean to open up the drive! Simply
hold the drive upside down so its electronics are facing up, and you should
see a central main-spindle and, off to one side, the stepper motor shaft.
You do NOT want to attempt the 2" drop-kick start as suggested by others
recently! :-)
