I'd like to back up my WSE 2012 R2 server to an external Seagate HD.

File explorer sees the drive (WSE assigns it a drive letter) and you can easily copy or delete files from it, however the WSE 2012 R2 Server back-up wizard does not recognize the drive at all.

I get an error message that says something to the effect that "The wizard cannot find any drives that are suitable for a backup destination ...."

I'm stumped. 

Hi:

Strange that it says there is nothing there.  Can you verify the format of the external USB drive?  It should by NTFS 4k sectors.  If not try formatting it to those specs.

Yeah, I suspect it may have a protected partition on the USB drive that is preventing WS2012E from seeing it as a viable drive for backups. Reformatting the drive (NTFS) should fix

Thank you for the replies, I've been out of town on business.

OK, I'm stumped, the drive has been formatted several times NTFS 4K sectors. It is completely empty. 

The Dashboard sees it fine, and when I try to add it to do server backups it comes back with that same error message.  I just reformatted it again, using the WSE 2012 R2 server to do it, still nothing.  It is an empty 1 TB Seagate drive.

Help? 

What model? Look here:
