What about on 6.5.2?

Does your USB disk have its own power supply?

I think the nas says firmware is up to date, will check when I am home.

The two seagate drives I have tried have external power supplies.

ReadyNAS OS 6.5.2 is now available!

It's available as a local update only at this time, but it should be avaialble on the update server soon.
