Can't access my hardrive  

Hi there, I've looked through some other posts but I just can't seem to fix my problem.

Currently, I have a 500gb Lacie external hd which was working fine a couple days ago but now it won't show up in my computer. So I went to Disk Management and it turns out that it had no letter assigned, I tried to change it but the option was grayed out. I also went to "cmd" and typed in Diskpart and list volume/disk. The hard drive doesn't show up under volume though, only under disk. Is there anything else I can do?

Thanks

How do I find the format of the drive?

Once I typed in active, it said no disk selected even though I typed select disk 1. Anything else I can do?

After I typed detail disk, this is what showed up:

ST350083 0AS USB Device
Disk ID: 2B682E15
Type: USB
Status: Online
Path: 0
Target: 0
LUN ID: 0
Location path: Unavailable
Current read-only state: No
Read-only: No
Boot Disk: No
Pagefile disk: No
Hibernation file disk: No
Crashdump disk: No
Clustered disk: No

There are no volumes.

Nothing is on the drive. It's empty.

EDIT: I also forgot to mention that it was previously formatted by a Bell TV Satellite receiver.
