IBM Ultrabay CD-RW/DVD Combo Drive Won't Load At Boot/Disa..

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

This all seems to be a hardware problem  . I can't explain it otherwise. Do
you still have warranty? Guess not, otherwise you would have already sent it
in  ...

There is however a 3-disk PC hardware doctor set available somewhere on the
IBM site. Boot from these three DOS boot disks and it will test the complete
computer. I am pretty sure the CD will also (at least after a while) also
disappear, the PC doctor program should detect this and then you are 100%
sure that it isn't a software problem (since you are not booting into your
operating system with these diskettes).

Alternatively you can also boot Knoppix, the CD linux and just let it run a
few hours (days?) and see if it disappears there, too, to also exclude the
possibility of a software problem. That CD is freely available from
http://www.knoppix.net but it is a huge download (~700 MB), so if you only
have a 56k modem, this isn't an option.


Just out of curiosity, what exactly does this mean?
"removed the upper/lower filters from the registry"
