To quote: Due to FAT32 limitations users needed to run these games from internal hard drive only. However, it seems that isn't the only option anymore. Many games utilize a file format known as PSARC (*.psarc).
These files ending in .psarc are archive files similar to zip or rar files on PC. By extracting these large archive files and using the smaller files that are inside, users can get stay under the 4GB limit.
This method has been tested on Uncharted II, and will only work on games utilizing the psarc file format.
1) Download PSARC.zip PlayStation Archive Utility (or the PARC GUI v0.1 or the PARC GUI v0.2 update by TeamKidneyBean if you prefer).
2) Extract zlib.net.dll and PSARC.exe to any folder.
3) Find any files more than 4Gb for example /PS3_GAME/USRDIR/build/main/pak22.psarc (5,596,444,529 bytes)
4) Copy pak22.psarc into zlib.net.dll and PSARC.exe directory.
5) Extract pak22.psarc (just drag-n-drop pak22.psarc to PSARC.exe)
6) Now copy pak22 folder with extracted files to gamefolder /PS3_GAME/USRDIR/build/main
7) Now you can delete pak22.psarc.
8) Copy PS3_GAME folder with game to your external fat32 usb hdd GAMEZ/Uncharted2/
9) Use Backup Manager to load game, should work fine.

I'm sure that someone else will try that as well and either confirm or deny if it works and - it was already suggested around here and in the +4GB file on external hard drive news thread to do so and I must confess that I've already dismissed that as not possible. I'll stay behind my opinion for now but I'll be more than happy to be proven wrong
I FTP'd the games to the hdd while it was hooked up internally.
Sorry for the double post, but yes the PS3 does format. If you hold down the power button until it beeps then shuts off, then do it again.... a menu pops up with options to format, fix file system and other things.
I have successfully achieved a way to have large files on the external, and it was quite simple honestly.
I only tested this on a 160GB drive, but I assume it works on any drive.
This is what I did....
1. Took a 160GB hdd and hooked it up internally.
2. Allowed the PS3 to install it's proprietary files, format, fix file system.
3. Booted to hack, filled up the hdd with games.
4. Put the drive in an external case and hooked it up via USB.
5. It works.
I did this 2 days ago and looked around to see if anyone else already did this. I found nothing.
NZHawk's Awesome MountPoint Manager v1.0 used with this method is great. It isn't hard to figure out what else to do. Naysayers will want proof, I'm not looking for recognition. I am just sharing what I discovered. I was curious, tried it and it works.
I do have a question though.... How hard would it be to make a homebrew app that would install the PS3's file system on an external without having to go through this process?
