I have two 16 GB memory sticks - one a sandisk cruzer U3 smart and the other a datatraveller. Neither is recognised by my Humax Foxsat HDR box - it says it cannot recognise the stick and I should format it as FAT32 or EXT3 using my PC. I have done both of these formats with my PC and still neither are recognised by the Humax box. Can I get the Humax box to format them? I should think this is impossible until the box at least recognises the presence of the stick. Any suggestions?
