The hard drive is stylish and unfussy, working as fast as USB 2.0 allows (30MB / sec), and easy - I had on several computers and laptops no problems with the power supply. The factory is with FAT32 formatted (probably so they just works on PC and MAC) and with some software enriched (Nero BackItUp and an ancient Adobe Reader for PC, MAC I have not tested). The software I have deleted and the disk formatted with NTFS (then go large backup files :-)).
If someone missed: (turned on and the computer), these drives have unfortunately no switch, ie as soon as the cable is connected, the drive starts up and runs off!
