Die Microsoft-Dateisysteme (NTFS und die FAT-Brüder) unterstützen UUIDs nicht wie ext * / btrfs / andere Unixy-Dateisysteme. Was als UUIDs gemeldet wird, sind Seriennummern (64 Bit lang für NTFS, 32 Bit lang für FAT32). Die einzigen konkreten Informationen, die ich aus der Linux-Welt ntfslabel(8)
herausholen kann, stammen aus der Manpage :
--new-serial[=ssssssssssssssss], or
--new-half-serial[=ssssssss]
Set a new serial number to the device, either the argument
value, or a random one if no argument is given. The serial
number is a 64 bit number, represented as a sixteen-digit
hexadecimal number, used to identify the device during the
mounting process. As a consequence, two devices with the same
serial number cannot be mounted at the same time on the same
computer. This is not the volume UUID used by Windows to locate
files which have been moved to another volume.
The option --new-half-serial only changes the upper part of the
serial number, keeping the lower part which is used by Windows
unchanged. In this case the optional argument is an eight-digit
hexadecimal number.
Ich vermute, dass diese "UUID" möglicherweise mit dem Seriennummernbericht von fsutil
Windows identisch sind .
