CT-40 Hard Drive Crashed - Help

[csny@rainbow.sosi.com (Charles Snyder)]

I have an Apple IIGS, ROM 1, 3.5 and 5.25 Apple Disk drives and until a 
couple of weeks ago, a Chinook CT-40 hard drive. About a year ago, I
experienced problems with the CT-40 in that it would periodically, 
"power down" and then would "power up" again - e.g.,it sounded as if
the drive would wind down and would wind back up again. This could happen 
on the average of a couple of times an hour-very annoying, but I never lost
any data from the hard drive. I took it in to get it fixed, and the repair
man replaced 3 capacitors on the power supply, and the drive worked fine 
for another year, until a couple of weeks ago when it started to do the 
same thing again, tho' with less frequency. Then, one day, as my drive 
was 
being written to, the "power-down" and "power-up" symptom happened again.
I could no longer access my drive. Using a couple of utilities, my hard 
drive would not be recognized. I took it in for repair. The technician
felt it might be the power supply, so, he put a new one in. I brought it 
home and found that utilities, such as the "GS Utilities" that came with
my CT-40 and the "Apple II High Speed SCSI Card Utilities" (yes, I forgot 
to mention that I have that card - not the RamFast) would not even recognize
the hard drive. I have checked everything, I think:
 *Power cord plugged in
 *Cable plugged in firmly to the Hard drive and to the SCSI Card (Slot 7)
 *Checked to make sure the SCSI numbers are not the same and are
not 8 or 9. (Card set at 7, drive set to 0)
 *Removed the SCSI terminator from the back of the drive (tried it
with it on and off)
 *Switched the cable to terminator terminal
 *Insured that the "Slots" Control Panel showed "your card" for Slot 7
 
Questions before I take it back to the technician, (who, BTW, is quite 
knowledgeable and helpful):
 
 1. Have I missed something in checking things out? (yes, I checked the
"troubleshooting" pages in the SCSI Card manual).
 2. Do you think I need a new drive (kinda obvious to me that may be the
case, but, I may be too presumtive)?
 3. Could the combination of the "power down" and writing to the drive
damage the drive mechanism?
 4. Could my SCSI Card have been damaged?
 
Feel free to respond via e-mail (csny@sosi.com) or post here-might help 
someone else with a similar problem.
 
Thanks for your help!
