Costly, but very good. Discovered early on that you cannot copy files over a certain size (I think 4GB) to this drive whilst it remains formatted in FAT32. Could take all files off and re-format to NTFS, but cannot be bothered at this stage. I now regulay play this drive through my Sony Blu-Ray player onto my Sony HD TV. Great quality. Have even watched films with this drive connected to my home network, still no power required, works off USB. GREAT! SUPER! Highly recommend. Have also not bothered using the built-in password features.
