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
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.
