|Some enclosures will not work with some drives. I have had this problem before, either the drive will spin up and work for a bit then spin down, or the firmware on the enclosure just will not access the drive until you do a proper initialization using the proprietary manufacture's software. |
You maybe able to see the enclosure in the device manager, but is your drive spining? Just put your ear to it. If it is, then the drive may have been encrypted by the old case or the new case doesn't want to work with it.
Try to find a desktop that you can use and an extra SATA cable. Plug it in there and if you can see it there it's your new case, if you can't then you may want to find someone to solder the USB jack back to the original enclosure.
Hope this helps
