I can get my tablet to use an external drive with no problems but I am looking for a mini size disk for travelling - say 1.8" or 2.5" that is NOT powered from the USB. The idea is to save power on the tablet. I am in the UK but anyone who has seen anything like this please let me know and I'll see if I can find a supplier in the UK. I've searched the net but many links are extremely old and sometimes refer to a storage device for photography to copy SD to the HD and I want something simpler (and cheaper). Thanks Note for Admin folks - any chance of a hardware forum for attachements - could be split into USB stick External disk Keyboard/Mice Wifi (for those that are not onboard) TV adapters (TV in/TV out/USB) GPS (for those that are not on board) etc. Would be really helpful if tablet independent.
