    USB disk rotation ?

    Is there a "best practice" regarding rotating external USB disk when backing up there ? I'd like to manually rotate disks if possible without needing to get into the UI - is it possible / feasible ?

    Move disk and keep data?

    My good old DS214 was killed by lightning a few days ago. The powersurge travelled trough the ethernetcable, and killed most other wired equipment. The DS214 powers on, but the network interface is fried. Time to buy a new, similar model. So my question is: If I use the same disks from the 214...

    DS220j / DS218j Disk Compatability

    Hello. My DS218j just hardware failed (all green case and power brick LEDs flash with the drives out). It's a little over three years old.

My logic is that I’m not too bother about losing the downloaded movies in the event this single harddisk fails. I will not need to restore the movie files in vol 2...
