Review on HWAYO 320GB Portable External Hard Drive, USB 3.1 Gen 1 Type C Ultra Slim 2.5-inch HDD Storage Compatible for PC, Desktop, Laptop, Mac, Xbox One (Red) by Brian Smith

The format for recording TV programs via a digital converter is not specified in the prospectus. I used FAT 32 or NTFS. Unfortunately I returned one as I thought it would not work with my Aluratek box. The format can easily be changed using a computer, and no internet is required either. When the device is connected to your computer, browse to This or My computer, look down to format and select the one you want. It is listed as HDD (E:).
