Huhu, spontan würde ich mal drauf tippen, das der USB Port oder sogar ein Teil vom USB Controller die Hufe hoch gerissen hat. Wie verhält sich denn die Platte an einem anderen System?

Hallo,
habe CentOS 6.5 x64, an diesem Rechner habe ich eine USB-Platte auf die mein Backup Programm Sicherungen macht.
Diese Platte hört plötzlich auf zu funktionieren und ist auch erst wieder nach einem Reboot nutzbar.
Wenn ich die Platte tausche und eine andere anschliesse dann wird diese auch, bis zum Reboot, nicht erkannt.
dmesg spuckt folgendes aus:

kann mir da jemand auf die Sprünge helfen?
Der Server läuft an sich durch, nur wenn die Platten wieder nicht erkannt werden muss ich neu starten.
Danke
