I’m having a very weird problem. This has happened to me before. Anything that my computer considers a removable drive, including floppy, DVD-Rom, my digital camera, or even a virtual drive, is unreadable unless I boot the pc with the media already inserted. In other words, if I put a dvd in, it says “Windows cannot read from this disk…” or in the case of my camera, it says it must be formatted. If I already have the dvd in when I boot the pc, it reads it just fine.
The last time this happened, I had Norton Systemworks 2005 installed. When I uninstalled it, the computer started working again. It happened again when I installed Nero and upgraded to OEM version 220.127.116.11 and accidentally ran BackItUp. I uninstalled Nero and removed all instances in my registry. I even tried uninstalling and reinstalling my drives, but it didn’t fix. I did reinstall Nero (without INCD) and I also have Alcohol 120, but it worked after I installed that, so I don’t think it is the problem. I really don’t want to do a reformat right now, and I did check the sticky thread on disks not being read, but nothing in there helped.
