First of all sorry about my english. I bought My Passport Essential 500GB (USB 3.0/2.0). I used this link to format in FAT32 ( http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm). After format my ps3 recognized but just the first time…in must of the forums talked about FAT32 requirements but what else?, what another requirements needs PS3 to read an WD External HDD?..the same situation happened when I tried with My Ebook Essential 1TB just the first time was read.  Greetings.
