IMHO the best is to take a cold, full backup copy right away, as you're doing with an USB drive. If both drives in the array were identical, the healthy one has now, statistically, a high chance of failing.
AFAIK you can rebuild and extend a 1TB mirror array into, say, a 2TB array using qnap's OS. However, rebuilding is a prolonged stress period for the HDDs, and there is a small possibility for failure of the 1TB healthy drive during the operation. I would take a full copy on the USB drive, then buy 2 new drives, create an empty array and fill it from the USB drive. It will take time, but you'll still have the original 1TB mirror in its current state in case something goes wrong 3 SB 3 Libratone Loop, Zipp Mini iPeng (iPhone + iPad) LMS 7.9 (linux) with plugins: CD Player, WaveInput, Triode's BBC iPlayer by bpa IRBlaster by Gwendesign (Felix) Server Power Control by Gordon Harris Smart Mix, Music Walk With Me, What Was That Tune? by Michael Herger PowerSave by Jason Holtzapple Song Info, Song Lyrics by Erland Isaksson AirPlay Bridge by philippe_44 WeatherTime by Martin Rehfeld Auto Dim Display, SaverSwitcher, ContextMenu by Peter Watkins. ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=107932
