recently i bought 2 HD.
WD 1.5T essential and WD 750GB my passport.

i format the 750GB but my ps3 doent recognize it, it works fine and my computer.

i also tried the 1.5t and it did work.

i was searching for and answer and found this post and the suggested that the HD possibly didnt get enough power

Now then, for those of you who intend to use this on your Ps3, pay attention. 2 things are required to make this bad boy work. First you'll need some third party formatter like swissknife to reformat the drive to FAT 32. Pay no attention to people who say you have to do a local format for a partition, not true. Just format the whole drive to FAT 32. This will not effect the transfer speeds in USB 3.0 either. Secondly you will need a powered USB hub! This is the key to making the hard drive work on the Ps3. You can buy them anywhere, they are about $15 and you'll know the difference because it will say AC adapter included on the package contents. The Ps3 USB port can't support the power that an external HDD requires thus purchasing one of these hubs will alleviate any complications. Plug the power into the wall, the USB end coming out of the hub into the Ps3 and plug your external HDD into your hub. Done, you can know use your external HDD on the Ps3.

im wondering if this is actually true or if i can fix with other options
