31 This is what it says right now.

45 BTW, it's sdb but I know what you wanted.  ;-)  As it is, that was done
46 with gparted.  It is still trying to put a ext4 file system on it and it
47 has been about a hour.  If I recall correctly, it took several minutes
48 on the 6TB drive a while back but nowhere near this long.  There's not
49 that much difference between 6TB and 8TB.  I might add, I did a
50 smartctrl -a for that drive, it took a good long while to retrieve the
51 data.  Generally, it comes back in seconds for other drives.  It seems
52 that everything is slow for that specific drive.

54 While I was typing all that in, it came back with this.

77 Yea, something isn't right here.  Given I've tried two different tools,
78 I'm going to check those cables and such.  ;-)
