if the harddrive came with a disk install it. if it didn't, go to the manufacturers website and try to find a driver for it.

Try going to Disk Manager and see if it is recognized.
Try assigning it another drive letter if it's there.
Click on START > CONTROL PANEL > ADMINISTATIVE TOOLS > COMPUTER MANAGEMENT > DISK MANAGEMENT

If it isn't there, try unplugging and replugging it.

There are so many problems that can occur with external drives that it's not a good idea to use them as a permanent backup. For instance, they are portable enough that they get banged around; the MBR can get corrupted; some have their own drivers and so on. There are many fixes depending on what the problem actually is.

Some of the fixes include: resetting the jumper on the drive from cable select to master; installing the drive internally in the computer (if possible) as a slave. Sometimes, a different enclosure works, occasionally because the drive is not supplied with enough power in the original enclosure.

At any rate, in future, it would be better to make sure all your data is securely backed up to a different source, such as CDs or DVDs.

You can also try to plug it into another computer to try to retrieve the data. Keep in mind that if it was formatted in NTFS it will not be recognized by a FAT32 computer, though it should have been formatted in FAT32. And it may not work with anything but USB 2.0.
