Nothing to say about this External Hard Drive I use it to record the HD with the new Dual-S terminal CanalSat and frankly it works IMPECT. The HDD starts up automatically when you turn on the terminal and vice versa. The recognition with the HDD and the terminal was without worries, except that now I can no longer use the programs I save in the hard disk on my computer is protected by CanalSat (ha well played copying lol). But if the recording is to go for HD and SD as well and I'm very happy, missing more than a few additional HD channels and there is joy lol Thank you amazon for its very fast send also. I will advice.
