No harm, but I wonder why! Most likely, the volume label of the disk was set to Lacie, and it has one now. Try setting one. $ apropos label e2label (8) - Change the label on an ext2/ext3 filesystem findfs (8) - Find a filesystem by label or UUID mlabel (1) - make an MSDOS volume label ppmlabel (1) - add text to a PPM image > 2- the first time I plugged it in, it was mounted as root.root with only > write permission for root....

For filesystems which have no notion of individually owned files on the disc (e.g. MS-DOS, FAT), the drive is mounted as belonging to a particular user. Which could be the person who mounted it, or according to uid and gid parameters in your /etc/fstab file. For filesystems that do understand ownership, the drive should be mounted with them being used as on the drive. Of course, this means that user 512 on the external drive must be the same as user 512 on the local system, but if you only use the drive with your own system, that's going to be the case, anyway. That's more of an issue when you swap drives between PCs. For filesystems with ownership systems, that you want to share files with, you need to make sure you make the files suitably readable as you save them. e.g. Group readable to a group common to both PCs, or world readable, if applicable. >> If you're about to reformat the drive, and therefor don't have to keep >> contents on the drive, you can test both of the above queries, yourself. > How could I go back to vfat file system? I have only linux machines. It's just another type of formatting option. Linux can make a VFAT filesystem, if you want. -- Don't send private replies to my address, the mailbox is ignored.
