The hard drive may be good; This is intended only to be pointed out that in any case they do not work with TechniStar S 2 from Technisat. Therefore, it was not suitable for my intended purpose. The receiver, who usually tried out all recording media - whether or FAT32 formatted NTSF - has certainly recognized and aptly, does not respond. This hard drive apparently requires more than the maximum provided by the receiver 500 milliamps to run. Although the hard disk tries to start, but it is not enough to bring the power LED lamp to light up. It looks so far out for a strong start-up current problem. A Skymaster receiver, PC and television bring the board up and running so that it is self-at least not broken! While here writes another reviewer that the Seagate décor in super with its S2. Possibly used Seagate but now other components. Whoever buys the plate to support the operation of the PVR TechniStar S2, which could run into problems. The Toshiba Store Basic 1Tb works instead by the way so far very good!
