Hi Randy714,
It's not going to be any of the issues that others have mentioned. If the devices fits the enclosure, than it will work. Also, if it were a cable issue, or enclosure issue it wouldn't be visible in the diskmanager.
It is possible that the drive has some unusual formatting or encryption, though I doubt that as well.
BUT, here's what you can do if you don't care about the contents.
Open a command line (in administrator mode) in Windows with the device connected in its enclosure.
At Command line prompt enter this:
DISKPART
Once you see the DISKPART> command prompt, enter LIST DISK
In your disk manager image, it's showing as Disk 2, it will most likely be the same, but you can validate that with the capacity of the "SIZE" column. So in the disk list once you identify which one is your drive, enter:
SELECT DISK 2 (assuming it's 2)
Then enter: LIST PART
It will give you a list of partitions on the drive.
There will most likely be only 1 partition, but this is just to verify if there is more than one.
What you can do now is completely remove all partition information from the drive first.
Do that by entering:
CLEAN (Make double sure you have the right drive first. It will be the one with an * on the left of the entry next to it when you LIST DISK).
After the CLEAN command finishes, enter:
CREATE PARTITION PRIMARY
SELECT PART 1
Now you can format it:
FORMAT fs=ntfs quick
Then you can EXIT diskpart after it finishes.
Now you can go back to your disk manager, you should be able to see the drive.
Actually, you should be able to see the drive (it will have assigned the next drive letter) in Windows explorer as well, with the full capacity of the drive available.
