PS3 Dual Boot Hard Drives help?

[n42100]

Ok, so im getting my ps3 the abilty to dual boot via the e3 or whatever, and i noticed you needed 2 hard drives for it to work. So i was wondering if i could use the internal as one, and use an external partitioned wester digital hard drive.

Would that work, and would i have to do something like format it. Thanks!

Yes it would work. I'm not sure if you have to format it first and make one partition. It's safer to do so.

But the ps3 will do it anyway cause it has to make its own file system.

you can use one hdd instead of two

Two drives is better. One for CFW and one For OFW and yes you can use 2.5 or 3.5, but I believe its better to have only one partition on it.
