I bought a WD Scorpio Blue WD5000BEVT dd - Internal HDD 2.5 "- SATA-300 - 500 GB -. to record movies and shows with my HUMAX TN5000HD I put this external enclosure Allcam USB2 (20 seconds!), NTFS formatted via my PC with Norton Partition Magic 8.0 and then Humax recognized and reformatted to FAT32 with creating partitions. I kinda wanted because I thought it was necessary to format it to FAT32 and given its size (500GB), partition magic did not do it. Overall I am very happy. SD is silent, very little heat. As it is self powered from the USB port of the humax, it turns off along the device. I highly recommend to those who need an external HDD to record television, the combined purchasing this hard disk with this Allcam housing.
This housing is cheap (less than 6 euros), a pity that the shipping cost are as high (10 6 euros!), But it is fine and screws (supplied with screwdriver please!) Are not even needed as it is clipped.
