[Cialug] Trying to label 2TB USB drive from Redhat 5.7

No clue.  Can't access the drive to read the label using Linux tools.  It
is a brand new drive so my guess it is GPT or MBR with NTFS partition.
The kernel says the device is "sdd1" yet /dev/sdd and /dev/sdd1 do not
exist for me to run fdisk or parted.

Here you go:

sh-3.2# ls -l /dev/sg*
crw------- 1 root root 21, 0 Jan 20  2013 /dev/sg0
crw------- 1 root root 21, 1 Jan 20  2013 /dev/sg1
crw------- 1 root root 21, 2 Jan 20  2013 /dev/sg2
crw------- 1 root root 21, 3 Jan 20  2013 /dev/sg3

sh-3.2# cat /proc/partitions
major minor  #blocks  name

   8     0  292968750 sda
   8     1     104391 sda1
   8     2  292856917 sda2
 253     0  282624000 dm-0
 253     1   10223616 dm-1
   8    48 1953514580 sdd
   8    49 1953410048 sdd1

sh-3.2# /sbin/fdisk -l

Disk /dev/sda: 300.0 GB, 300000000000 bytes
255 heads, 63 sectors/track, 36472 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14       36472   292856917+  8e  Linux LVM
sh-3.2#



I see the major/minor device numbers for sdd and sdd1...I guess I can try
to just mknod the devices.  Will give that a try...
