UUID in Mountain Lion

Question

I am trying to find my external HDD UUID in Mountain Lion but diskutil info /dev/disk1s1 returns:

Najis-MacBook-Air:~ ****$ diskutil info disk1s1
   Device Identifier:        disk1s1
   Device Node:              /dev/disk1s1
   Part of Whole:            disk1
   Device / Media Name:      Untitled 1

   Volume Name:              My Book
   Escaped with Unicode:     My%FF%FE%20%00Book

   Mounted:                  Yes
   Mount Point:              /Volumes/My Book
   Escaped with Unicode:     /Volumes/My%FF%FE%20%00Book

   File System Personality:  NTFS
   Type (Bundle):            ntfs
   Name (User Visible):      Windows NT File System (NTFS)

   Partition Type:           Windows_NTFS
   OS Can Be Installed:      No
   Media Type:               Generic
   Protocol:                 USB
   SMART Status:             Not Supported

   Total Size:               2.0 TB (2000364240896 Bytes) (exactly 3906961408 512-Byte-Blocks)

   Read-Only Media:          No
   Read-Only Volume:         Yes
   Ejectable:                Yes

   Whole:                    No
   Internal:                 No

And there is no UUID. What is wrong exactly?

Thank you.

Solution 1

Actually

diskutil info disk?s?

doesn't provide UUID but using the following does:

diskutil info /Volumes/YOUR_DRIVE_NAME

Solution 2

On my Mac (Mountain Lion) actually both commands

diskutil info disk?s?

and

diskutil /Volumes/YOUR_DRIVE_NAME

provide the same information. Note that a FAT (MS_DOS) formatted volume does not have an UUID. If you format it to Mac OSX Extended format, it will!

Solution 3

The drive you are trying to access is of Windows_NTFS Partition Type. So it doesnt show the UDID of the drive. For further accessing of the drive follow the steps given in this old blog( which shows steps with respect to 10.6), but would serve your purpose as the MAC OSX never changes its backend core.

My linux box sees some strange 8-letter "UUID"'s for vfat volumes. Is it possible to get them here?

$ diskutil /Volumes/MINISD8 and I got diskutil: did not recognize verb "/Volumes/MINISD8"; type "diskutil" for a list
