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

And there is no UUID. What is wrong exactly?

Thank you.

On my Mac (Mountain Lion) actually both commands

diskutil info disk?s?


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!

My linux box sees some strange 8-letter "UUID"'s for vfat volumes. Is it possible to get them here? – Equidamoid Feb 10 '15 at 12:52
$ diskutil /Volumes/MINISD8 and I got diskutil: did not recognize verb "/Volumes/MINISD8"; type "diskutil" for a list – Frozen Flame Aug 31 '15 at 13:08

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.

diskutil info disk?s?

doesn't provide UUID but using the following does:

diskutil info /Volumes/YOUR_DRIVE_NAME
