64GB Kingston DTSE9 USB flash drive not detecting

Afternoon,

Not sure if I have formatted my USB drive incorrectly (Tried NTSF and exFAT) but my WD TV Live will not detect it anymore.

Does anyone else have the same issue? should I try formatting it to a lower size?

It works fine on my USB HDD caddy with a 250gb NTFS drive

Thanks

WDTV does not support ExFat.
