Have you tried the suggestions Ramesh posted? I don't see it being an MS update
issue, all of my machines are fully up to date and have no drive issues.
Did you uninstall ANY/ALL DVD/CD ROM drives in Safe Mode > Device Manager? Did you
attempt it with the drive(s) physically disconnected from all power? I realize you
mentioned previously that it wouldn't boot to Safe Mode yet I have to ask.
Also, what you mentioned earlier means you never saw the Safe Mode prompt at all,
correct?
Have you connected the drive(s) to other machines with know working drives to see
if the drive(s) is/are the problem or not?
Have you tried swapping the data cables for known good working cables?
Have you tried a System Restore to a prior date of removing the device letters
previously mentioned?
Have you tried it at a Safe Mode command prompt.
Have you thought about a Repair Install if all else fails?
Normally I can provide links to articles but it appears I borked the file I store
them in and they're all plain text now. Once I restore it if you would like to have
them let me know.
