Since approx. 1 week I have an extremely irritating
problem with my 2 CD-ROM drives and my DVD-ROM drive
(under Windows XP Professional), although I did not
(myself) change anything on my PC HW or SW installation.
My drives suddenly recognize (official as well as own-
written) data CD-ROMs and (official) DVD-ROMs only once
and only after they have first read an official audio-CD.
When I unload and load the drives with the same data CD-
ROM or DVD-ROM (that were perfectly accessible before the
unload), they either do not detect the CD-ROM or DVD-ROM
at all, or they recognize them as empty.
When I load an official audio-CD (which is always
correctly recognized and accessible without any problem),
unload it again and replace it with the earlier data CD-
ROM or DVD-ROM, the data CD-ROM is again recognized and
accessible (until the next unload). A DVD-ROM on the
other hand causes my PC to reboot, after which it is also
recognized and accessible (until the next unload).
Can this be due to a recent Windows XP Security update (I
have Windows Update set on automatic) or one or other
security setting in Windows XP that I may accidentally
Can I undo this?
