ps3 doesn't recognize my external hardrive usb 3.0?

this the hard drive i have is "western digital my book essential 3tb usb 3.0’, i hav formatted it to 2 partitions one is 2tb fat32 and the other is 1tb ntfs. and my ps3 doesn’t recognize the fat32 partitions !!! any help would be much appreciated!! the hard drive supports both 2.0 and 3.0 usb.

Might be a problem with USB 3.0 cable, try using a normal USB 2.0 cable instead.
