My current set up is a 1T WD HDD that has external power from wall socket that my TV recognizes and provides access to my folders and files - music and videos. My HDrive is starting to act sketchy so I thought I'd buy another drive and transfer the files before it goes out since there is no other back-up. The reason for my question is, I've tried to see if a memory stick would be accessible by the TV and it doesn't recognize it. It made me wonder if this was a power source issue - ie, does it need to have an external power source for the Hdrive. I don't have any portable HDrives to test it out on and before spending on another HDD or SSD if this is something I should consider. I looked at the recommendations by Tom's on drives but none of them have an external power supply. So my question here is, does anyone have experience with this? (I can be more specific on the hardware like the TV specs but I thought I'd ask before I do that). Thanks and Regards,
