LACIE Rugged Mini USB 3.0 bricht Verbindung ab

[rolfti]

Hallo, es geht um die LACIE Rugged Mini 2 TB USB 3.0 die zwischendurch als Backupmedium eingesetzt wird.
Startet man ein rsync der länger andauert wie z.B. (backup_vmware) bricht sie plötzlich die Verbindung ab und
verlangt erneut die Passphrase zum Entsperren (cryptsetup) des Datenträgers.
Kleine Backups rutschen ohne Fehlermeldung doch sobald es sich um xGB handelt bricht es zusammen.
Das gleiche Übel mit der SANDISK Extreme Pro (USB 3.1, 2 TB, Orange, Schwarz).

Hier ein Auszg:
