Hi
Try accessing to Disk Management ( Start > right click on Computer or My computer if you have win xp > on the Computer Management window click on Disk Management )
If the drive is healthy everything is fine but if the drive is unalocated then you will have to format it.
If you don’t see the drive there then my recommendation will be to replace it.
