I have the NOWS 2 (SLES 10). After updating to 2.5 NOWS have a problem with the external USB drives. For backups I use a dock with 2 slots for SATA drives so I always have a set of discs in the Save. By this way I can lose in an emergency maximum the work of one week. Before the update each drive has the dock separately mounted automatically. Since the update I can only mount one of the two drives. If I want to see the other disk the system is automatically logged off the first disk and mounting the other. However, I need simultaneous access to both disks as before.
