Yes, there's an installation CD but it does not contain drivers. If the USB device is showing up as not recognized on multiple computers then one of two things are happening:
- The USB to HDD control board is dead (hence the device not being able to signal to the OS what kind of storage device it is, capacity, etc.)
- The HDD internally is dead
Finally, the context that you were using for backup was that your data was stored in one location. That's not backup, that's a source. We don't offer instructions on disassembling these devices per our forum guidelines. These are not lectures, they are responses to your asking for help. Don't get upset at us because we don't have the end all be all solution, please.
