The early suns were very picky about which drives they liked. There was
an issue with the read size and when the software would change from I
think the standard CDROM 2k size reads to 512, most cdroms would choke
Use a Sun411 (with a real sun 411 drive) which I think were toshibas and
one other brand, or a plextor. The Toshiba 3401's became very popular
because there was a jumper you could change to render them functional on
sparc stations back in the day, and they were much faster than the
drives in the original 411 cases.
I'm putting in this bit of explanation because of your first paragraph.
If you supplied one of your own Cdrom drives this may be the problem.
