The UUID is a Universally Unique ID; it is a 128-byte number, constructed using the rules specified by RFC 4122. See: http://www.ietf.org/rfc/rfc4122.txt You can set the UUID to something else, although the only way I suggest people make use of this functionality to use "tune2fs -U random" after doing an image copy of a file system. The whole point of a UUID is that it should be universally unique, and humans are notoriously bad at picking ID's that are truly unqiue. > The first link in the list is interesting :) > > I think the reason the USB has SO MANY errors on the FS is because I > possibly unplugged it, before umounting it! > > I understand that the umount command flushes any disk I/O buffers > back to the drive? Correct; I'd do a sync after the umount just to be absolutely sure, though. IIRC the umount doesn't wait until the USB stick has acknowledged that it is done writing everything to flash. - Ted _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
