Adding external USB HDD and Oversight

[Netmask]

A follow up - the Seagate 2TB seems to partially switch off after about 2 hours inasmuch I can no longer copy from my PC over the network. I get an I/O error message. The strange thing I can still play files off the drive on both the C200 and over the network. To fix the problem I have to turn off the drive by formally detaching and then reattaching (wish there was a menu item on the remote for this). I have downloaded a Seagate tool called FreeAgentCN to check what the power management is doing and altering hopefully the time to say 5 hours.
This model does use Green technology so maybe this is the problem. But it would be good if it were possible to "reattach" a USB drive already physically attached rather than having to pull the plug out and pop it back in for the Popcorn to recognise... any thoughts?
