I've done some tries and it's a little astonishing :
- When I reboot the box with the fstab modified, Movie Player sees the new name even if I haven't plugged the disk and I can also see it from Windows Explorer while the plugin Dream-Explorer don't see it nor the system initializer (from the settings menu).
- When I connect the disk, no change for Movie Player and Windows Explorer except that I can see the contents of the disk . Dream-Explorer sees "external storage sdc" (or sdb) .
- When I added another line for another disk, I have big problems and crashes, then I examined what I have written in fstab :
UUID=0e43c540-a28e-4e09-9ba8-0177b38cb4cf /media/hdd-backup auto defaults 0 0
UUID=5537e3aa-12aa-4ec0-a822-c31b0a13a02a /media/hdd-supplem auto defaults 0 0
It was similar as I saw in fstab but it was not the same thing than Biki. Then I replaced it with :
UUID=0e43c540-a28e-4e09-9ba8-0177b38cb4cf /media/hdd-backup ext4 rw,data=ordered 0 0
UUID=5537e3aa-12aa-4ec0-a822-c31b0a13a02a /media/hdd-supplem ext4 rw,data=ordered 0 0
And it works, it seems I have no crashes any more. But these names appears even if the disk aren't be connected and it doesn't change if I connect them. A little surprising. At least, the name remains the same if I boot (sdb) or not (sdc), that' what I wanted but if somebody have an explanation for the fact the name appears always, it wouls be more convenient.
Thank you .
