Ext. usb-festplatte Zugriffs-Problem

Hallo,
ich benutze eine 1TB Trekstor Ext.Usb-Festplatte um Backups per rsync zu machen.
Dabei steigt die gemountete Platte des öfteren unvermittelt mit folgender Fehlermeldung aus:

"rsync: writefd_unbuffered failed to write 78 bytes [generator]: Broken pipe (32)"

Das Systemlog berichtet:

Wenn die Platte ausgestiegen ist, läßt sich kein "sicher entfernen" mehr ausführen.
Bleibt nur ausschalten und wieder einschalten. Habe ein fsck darüber laufen lassen, wie man am Ende des logs sehen kann.
Noch ein paar Infods zu USB-Platte und System:
- Trekstor DataStation maxi m.u 1TB formatiert mit ext3
- System: Opensuse 11.0, Kde 3.5.9
- Board verfügt NUR über USB 1.1 Controler, USB 2.0-Controler mit Via-Chipsatz (PCI-Karte) nachgerüstet.

Wo könnte der Fehler liegen? Hat jemand eine Idee? Falls zur Diagnose noch Daten fehlen, welche?
Das es mit dem "BUFFER I/O ERROR" zu tun hat ist klar aber was führt zu diesem Error und wie kann es behoben werden?

Tom

Hi Tom

Ich habe vor kurzem von einem Bug gelesen finde den Eintrag im Moment auf die Schnelle aber nicht mehr.
Ausserdem kann ich im Moment nicht sagen ob das bei Debian oder Suse war, ich muss erst selbst suchen.
Welchen Kernel fährst du?

cu

hi,
kernel 2.6.25.16-0.1-pae. komischerweise funktioniert das Backup mit rsync wenn ich über Netzwerk über den PC meiner Frau sichere, d.h. die 1 TB Platte bei ihr anklemme :???: Kann aber nicht Sinn der Sache sein jedesmal zwei Pc's hochzufahren wenn ich was sichern will.
Merkwürdig...

Hi

Das war bei Debian und schon etwas länger her.
Vielleicht interpretiere ich die Meldungen aber auch falsch.
Du hast aber dies an einem USB2 Anschluss und keinen HUB dazwischen?

cu

Also ich habe ein Board mit (onboard) USB 1.1 Controler und später einen zusätzlichen USB 2.0 Controller (PCI-Karte) eingebaut. Daran ist die Platte angeschlossen.
Deaktivieren des USB1.1 Controllers habe ich schon gemacht, bringt aber keine Besserung.
