The symptoms you describe are consistent with the infamous dust
problems.  Another possible remedy may be SCSI termination.  Check that
you only have one external terminator (assuming you have an internal
hard drive) and that terminator is at the end of the chain.  You might
try the terminator in-line with the cable rather than on the other
connector; that's a bit of massive black magic that sometimes works for
me.

You can get the drive fixed free under the repair program, assuming it's
still going on.  I don't recall if there was a termination date on the
repair program.  Contact your local Apple dealer for details.  For your
local Apple dealer, call 800-538-9696 in the USA.

You can get the latest CD-ROM software from apple.com in the directory
~ftp/pub/dts/sw.license  The release is 3.01; the CD-ROM driver is
version 3.0 from December of 1989.
