    Hello,

    I have upgraded my computer from windows vista to windows 7 home premium last week. Everything is working fine but now my upgraded computer is not showing the external hard drive. When I plug in the external hard drive then system notices it but not showing on my computer. I updated all drivers and all are working fine. The window is not showing any update or error. I have saved some important data on my hard drive. Someone, please help me resolve this error.

    If your system is not able to assign drive letter then also this situation arises. So simply check the drive letter if the system is not able to assign the drive letter. Then assign the drive letter and your problem will be solved.
