I have a 2TB Western Digital MyBook Essential External Hard-disk. I wanted to use the Hard-disk as an internal hard-drive for my PC running Linux Mint. So, I dis-assembled it, and took out the SATA Hard-disk. Now, I assembled it into my PC using the SATA port.
The hard-disk's partition are not recognized now. In GParted. it shows as follows:
I then took out the hard-drive and assembled it back into its external USB case. It is recognized just fine now.
I am stumped. What might be causing this? The hard-drive is recognized just fine in its external USB case but NOT when connected through internal SATA.
