|If above does not work (or completely work), look in disk manager. If it appears in Disk Manager then you need to partition and format the drive. If you are planning to recover any files that were on the drive then use Quick Format (does not overwrite the entire drive) and Format it to the same file type (FAT32 or NTSF). If you do not plan on saving any files and you plan on using it only for XP and later Windows computers, use NTFS format but if you want it more universal (Mac and older PC's) then stay with FAT32 format.|
If it does not show up in Disk Manager or Device Manager then try it on another system to see if you can get it working that way. If not, you can try removing it from the case and installing it as an internal drive and Partition/Formatting it that way and then putting it back in the case. If it is recognized internally but not externally, it may be possible that you deleted a required Firmware, file, or partition that would allow it to work with the case's interface.
You have to be a little bit crazy to keep you from going insane.
