Windows 7: External hard drive not detected---again

Sometimes programs like tuneup utilities and spybot search and destroy have access to your registry, Any type of program that you may have that associates itself to it?



Also try going into your bios and boot priority plug in your external and then turn off your main hard drive and if it does not show up in bios just keep your main hard drive disabled and reboot then it should force boot the external hard drive, it happened to me with an external cd drive.
