Also with exfatprogs 1.1.0 [1], tune.exfat and exfatlabel gained the
capability to report and set the exFAT Volume Serial Number [2][3][4].
This is what blkid and therefore GParted reports as the UUID.
Report serial number:
# tune.exfat -i /dev/sdb1
exfatprogs version : 1.1.0
volume serial : 0x772ffe5d
# echo $?
0
# blkid /dev/sdb1
/dev/sdb1: LABEL="test exfat" UUID="772F-FE5D" TYPE="exfat" PTTYPE="dos"
Set serial number:
# tune.exfat -I 0xf96ef190 /dev/sdb1
exfatprogs version : 1.1.0
New volume serial : 0xf96ef190
# echo $?
0
tune.exfat exists in earlier releases of exfatprogs so check it has the
capability by searching for "Set volume serial" in the help output
before enabling this capability.
# tune.exfat
exfatprogs version : 1.1.0
Usage: tune.exfat
-l | --print-label Print volume label
-L | --set-label=label Set volume label
-i | --print-serial Print volume serial
-L | --set-serial=value Set volume serial
-V | --version Show version
-v | --verbose Print debug
-h | --help Show help
(Note the cut and paste error reporting the set volume serial flag as
'-L' rather than actually '-S').
