Would this information possibly help us to change the partition size of a retail (unconverted) PS3 hard-drive?

I only ask because I have a 1TB internal drive and as many others have discovered only 827GB are actually available due to the system reserving 10-12% of the total drive capacity.

I saw this and thought maybe there would be a chance at manually increasing the size of that 827GB partition using this method.

Maybe I am dreaming here but please respond, anyone who has some insight into this problem or any known way of regaining some of that lost space. Thanks!

This info wont help you achieve what you want but there are some ps3mfwbuilder tasks that can do what you want although I do not know if they work on firmwares greater than 3.55. search the ps3devwiki for ps3mfwbuilder and you will find the tasks I am talking about.

Well I finally had a chance to mess with PS3 MFW Builder. Is this the "task" I need to use?:
--patch-emer-init-gameos-hdd-region-size-xxgb-smaller

I built a MFW using this option, installed from recovery menu, and re-formatted the hard drive but it's still showing 827GB free.

BTW I am using the official CobraUSB 3.55 CFW on a CECHA01.

just to inform: I have succesfully converted my bdemu 640 gb external harddrive, to a hdd with a 300gb partition for bdemu, 28gb ntfs, and the rest of hdd space(250gb or so) to fat32. i just replaced/inserted the hdd size string to "00|00|80|25"(like in the tutorial) so it allocates 300GB for bdemu.
I'm not sure if its just me, but it initially corrupted the bdemu partition ( because games images on the drive rendered corrupt), but after wiping all games that where on the bdemu partition (with aldo's partitionbdemu drive tool) and re-copying the games to the drive again, all was well.

games loaded fine again from console.. this time from my 300gb dedicated bdemu partition. and the best thing... my ntfs and fat32 partions work also, alowing me to load 3.55 backups on the same 640gb drive

WARNING:
If anyone makes a custom partition for bdemu(like i did(see above post of mine)) with this guide.

DO NOT SET ACTIVE BDEMU GAME WITH MULTIMAN, AS IT WILL RENDER YOUR CUSTOM PARTITION TABLE USELESS
however you can recover, if you set the string back to the value u use beforehand in winhex(to allocate size), and use a partition recovery software to recover the ntfs and fat32 partitions.
