I haven't got a clue

 I have a Sandisk ultra 64gb backup " sdcz40-064g " that I got so I could put movies on and that I switched the format to both exFAT and NTFS,  Vista won’t give me an option to use FAT32,  but can’t get it to work in BR player plugged to TV and I could only find backup drivers for it

 My question is  " what other drivers do I need to put a movie on the backup-drive so I can plug it in and watch it on the TV through the player ?

It won’t even play a small 230Mb file, I even tried just a music video file and nothing.

 It’s a SONY br player and it’s supposed to play everything but all I get is a msg saying that the USB isn’t supported.

 Any help would be greatly appreciated.

 Thanx and I hope someone can help me with this.

the issue is probably that the sony device does not support exFAT or NTFS. windows limits FAT32 file systems to 32GB. 

you can use the HP disk storage format tool (download availabel here) to format the drive in FAT32. hope it helps
