There are a couple of solutions to this....although I am not sure your thought that the camcorder will be able to copy directly to a usb hard drive is correct.
Firstly, I dont think you will run out of space but thats not the issue.
Second the camcorder breaks video into 2GB files regardless of how long you 'record' (see the handbook for this 'note')
Third, do you have a sony memory stick ?? (8GB is about £50 or less) and you can copy the 2GB files onto the card and then use a photo storage device to back up the files. No problems with this at all.
Forth, if you want to 'try' the USB hard disk route, then try this device or similar----but not rumoured to be that reliable.

Personally I favour the copy to card and back up the card when on location, such as the on the go mentioned in the other thread or the ones such as

There are lots of these devices out there;

Take care with these devices though. Some create a new directory on disk for each backup from a card, others overwrite the same directory. The Vosonics type has a little more intelligence but is more expensive (you can view your fotos though !)
