Am having a recurring problem when installing programs via
cd-rom and cdr-rom (scsi). Will get a ...218 crash. registry info loss.
usually Winnt\system32\config\software or sys. Requires a reinstall of
Windows 2000 o/s to fix, as the recovery console will only accept three
commands when system won't re-boot, and no can copy the missing file.
There is no problem installing downloaded programs. So I am ruling out
defective hdd, although I can not presently reformat with recovery console.
This is an older(2000) SuperMicro Super P111DM3 M/B. On board scsi,
Adaptec AIC 7892. 2x933 intel slot one. I gig ram. Yamaha 8/4/24 scsi
burner, and scsi cd-rom.

I have not seen any indication in the Windows 2000 event viewer that there
is a scsi problem. There is no indication from the M/B (beep error
message) that there is a problem. The hdd's are on the U 160 lvd/se bus,
the cd/cdr-rom's are on the ultra 2 50 pin bus. Also, this computer has
never had the ability to boot from the cd-roms.

So my question finally, is there anything out there that can run a
diagnostic on the scsi host controller? Keeping in mind that I have not
been able to reformat the hdd. Would prefer not to do a llf.

I do have your book, 12th edition, but cannot find an exact answer, even
though you provide an extensive amount of info on scuzzy drives.

I also have not been able to find anyone in the local Computer Shops that
knows anything about scuzzy systems. In fact, they do not seem to know
much about anything for this particular Computer. They will sell me a new
one, though. That would solve the problem, but I have resurrect this one
first.

Hope you can answer this long e-mail, because I have run out of options
here.

Optical drives are one of the more failure prone components in a PC. Your
old SCSI CD-ROM drives may be defective, try installing a single ATA
optical drive temporarily as a test. You could also check the SCSI bus that
the drives are attached to for proper termination and cabling, but I
suspect your optical drive(s) have failed.

Re: the drive reformat, but your BIOS Setup may have Virus Protection
enabled, which prevents writing to the boot sector. Be sure any Virus
Protection is turned OFF in the BIOS Setup, then repartition and reformat
the drive.

SuperMicro or Adaptec may have SCSI diagnostics and format software, check
with them to see what is available for your board.

If you can't boot from your current optical drives, then I'd definitely
recommend discarding the two SCSI optical drives you have now and
installing a single ATA optical drive instead. You can get dual-layer DVD
burners for under $30: http://tinyurl.com/34qcnw or CD burners for even
less. That will make it much easier to install an operating system in the
future as well.

Let me know how things work out in the end, Scott.
