Pros Quiet, Easy to install
Cons Slow, unreliable
Summary I backed up 250 Gb from a Dell W7 Laptop, 70Gb from a new HP W7 laptop and 60 Gb from an Old Toshiba XP laptop. On the third backup of the Dell the software could not get beyond the file search (tried 2 hours) and same happened on the HP. I had to remove backup data from the C6 and run backup again. XP system worked ok. It is now beyond return date by a couple of days and I note the vendor I bought it from no longer sells it. No manual available but the original 16 language 3 foot by 3 foot sheet with a tiny bit of english on it says something about leaving the C6 plugged into the AC and this is what I did on second complete backup of the W7 computers. Terribly written and unclear just what was requried. One would think one could take the C6 to the computers instead of computer to the C6. This is very time consuming and have not had time to see what procedure works and what does not. I really hope it was somethng I did but can't imagine what it could be since one has no control over what it does once you plug in the USB.
