Muss man eine externe USB-Festplatte manuell umounten?
Hallo,
ich benutze meine USB-Festplatte um mit rsync /home-Daten zu sichern.
Mein System:
sarge:~# uname -a
Linux sarge 2.6.8-3-686 #1 Thu Feb 9 07:39:48 UTC 2006 i686 GNU/Linux
Wenn ich die Platte einschalte wird sie automatisch eingebunden, siehe Auszug
aus /var/log/syslog:

Muß ich die Platte vor dem Ausschalten manuell umounten, oder wie ist der
Eintrag "lost page write" bzw. "FAT bread failed" zu deuten?
Vielen Dank für Hinweise.
