I have a humax fox (500gb drive) humax pvr (fox sat hdr T2 ) and I have a spare 2tb drive that I could use as an external drive to copy humax files too eg movies and tv programmes etc, (to use as amedia player) is there a maximum drive sizei can use to format to my humax or is there a limit as I would like to copy mor humax files to drive yours bbuk

I'm not sure what this part of your question is asking.
If you want to format for your HDR-FOX then if you format via a computer you can use a partition up to 2Tb.
If you want to format by your HDR-FOX then the limit has been 1Tb.

Sorry I was using my tablet to ask this question and kind of got lost asking, so here goes If I format my 2tb via a computer can I "copy my humax files" that I have at the moment (1tb drive) to my re-formatted 2tb drive ie copy from 1tb drive to my Humax pvr and then copy back to 2tb drive and also continue to copy new humax files to my 2tb drive, if so what do I format it too many thanks in anticipation bbuk
