These drives look normal enough, I don't know of any problems offhand with
them. So I don't really know why your drives aren't spinning up.
Here are some things to try:
- boot with -v (boot -v) and see if you get any additional diagnostic
information when you spin down a drive and then try to do I/O.
- try the attached patch, and see if you get any diagnostic printouts.
Also, make sure you compile your kernel without excluding the sense and CDB
strings, so the error messages make more sense.

That's normal. It's just telling you there is no CD in the drive.
