I have a brand new Dell with Windows 7. I have four external hard drives. Windows 7 recognized one of them but will not let me initialize the others.
One of them is a brand new Western Digital which I used for a few hours on my XP. The device manager recognizes the disc and says it is working properly, but when I go to disc management and try to initialize it, the message "device not working" comes up. I do not believe it is a problem with the discs because they were all working fine with my old computer, but now I am getting the same problem with all of them.
I have seen similar problems addressed here and elsewhere, but never in regard to Windows 7. I have seen this problem with Windows 7 mentioned before with no solution.
