Stygmata wrote1- you should use usb2 where HDD REC is written for the hdd record
2-Once it has been formatted by the Bravia TV, the USB HDD cannot be used with a PC unless it is reformatted by the PC, which would erase the recorded data.
3-USB viewer supports FAT16, FAT32 and exFAT file systems.
There are no mention of HDD REC near any port on the TV, it's weird because it's written on the same model but European!
Middle East is always considered as barbarian perhaps so they take out some options like that.
I want to use it part backup for my PC and part for movies to be watched on TV
