I had an external backup (Seagate 1TB USB HDD with a load of stuff on (which wasn't all on the internal HDD - I'd copied off a failing internal drive before replacing it) as I've had two internal drives fail so far. However this week the external HDD has died - not recognised by Humax or laptop. Oh well, it was only telly. But some of it I'd quite liked to have watched. So I need to get another external HDD, and I guess I should really get a second one as additional backup. So, if I "move" files from the Humax internal drive to the external drive, can I then use a PC/Mac to copy the files from one external drive to another?
