A while since I did this but I would guess 15 to 20 hours. Make sure you have turned off the automatic power down after three hours without user input.

Providing there is no decryption during the copy then copying to the newly installed drives handles almost 50GB an hour. Keeping the HDRR tuned to a data channel during the process also helps to achieve 50GB an hour as it stops the live buffer being written.

Thanks for that , just checked I had the auto power down switched on and will remember to switch to a data channel.

I managed to copy all the media files over to the new HDD and everything seemed to be running ok apart from today when I started to watch something on iplayer. The picture froze after about 30sec and then my T2 rebooted, played for another 30 sec and then rebooted again so I gave up. The only other changes Ive made is to the custom firmware updating to 3.03 from 3.00 I had before. As anyone else had any problems with 3.03 ?

This happens only on iplayer not when watching media recordings
