DEX Partitioning –
Conflicting Reports, needs more testing so please let us know your experiences
You can use any usb hdd no matter the size but there are 2 ways to create DEX partitions:
On the PS3:
Any drive under 1tb will use the whole drive but still only have 4 partitions with no free space and 45gb per partition, but just say it's a 120gb drive you will end up with 2 45gb partition and 1 30gb partition
4gb drive = 1x 4gb partition
120gb drive = 2x 45gb DEX partitions and 1x 30gb partition
1.5tb drive = 4x DEX partitions and 500gb usable space
With ps3gen on your computer:
If you partition it with ps3gen any drive with 190gb or under will always have four partitions even with a 4gb drive you will have 4 1gb partitions BUT if the drive is larger than 190gb you will end up with 4 45gb partitions and the rest of the space will be usable.
4gb = 4x 1gb partitions
120gb = 4x 30gb partitions
1.5tb = 4x 45gb partitions and 1.2tb usable space
Free space after DEX partitioning can be used however you want without effecting the DEX partitioning/Games, I use the free space for all my 3.55 compatible backups.

looks like you're handling the CEX2DEX section very well. I've got a correction for you. On the PC using PSGEN with my 120 gig hard drive it would format it as 4x45 gig partitions for a total of 180 gigs. Check your PC's hard drive manager or EaseUS. Obviously since there's not 180 gigs on that 120 gig drive it breaks the structure and becomes unusable for the 3rd and 4th partition. On the PS3 it would format it correctly as 2 45 gig partitions and the remainder as the third. No fourth partition
I get the same result as you when formatting on the ps3 except that when the hdd is over 190gb eg. I used a 1.5tb drive, I still get 4 partitions but when checking with a hdd manager, I use easeus, the amount of data used for "Other"(DEX partition) is 1024gb with around 400gb unallocated. It's a little different for me with ps3gen, I tested with a 4gb thumb drive and when I tried to load a 2gb game it gave an error about half way through which I guessed was because since there was 4 partitions then they were all 1gb which was why it errored half way through a 2gb game. When you partitioned the 120gb are you sure you didn't get 4 30gb partitions and the reason the 3rd and 4th partition wouldn't work is because you tried a game over 30gb on those partitions.
Edit: When I formatted the 4gb drive on the ps3 the 2gb game worked fine.
No, the partition table when you check it in administrative tools/computer management shows 180 gigs when formatted on PC, but it shows as 120 gigs when formatted on PS3. I never tested any game bigger than 10 or 15 gigs I think
That's weird, disc management shows the same amount of data on my 4gb drive whether done on ps3 or ps3gen, what version of ps3gen are you using?
I haven't done it on the latest. I used the one that was floating around when DEX first came around to the public. It might be my hard drive enclosure causing the problem. It's cheap
Cool, I just want to get all the info I can so I can update my DEX thread with right info, I'm also going to add a FAQ section but again I want to get all the correct info. And I think adding a few spoilers would work better so it's not just one really long post.
I really hope more people comment on their experiences with DEX because there has to be much more people on DEX than there was only a couple of weeks ago.
If I've got a big drive (1.5TB) that's already got a bunch of stuff on it (~500GB-750GB), if I send it through ps3gen is it going to format my drive or partition through any files that are currently on my drive? I know that some partition tools let you decide where to make the partitions (although they of course still hold a warning that you may lose files), so I was wondering if ps3gen also had something similar.
I haven't gone to DEX yet, and this is the only that might stop me, since I've only got the 1 drive for all my backup purposes and I'd rather not lose anything.
ps3gen completely formats the drive with its own proprietary partitioning scheme and filesystem, so to answer your question, yes you will indeed lose all of the data on the drive by using ps3gen.

There is a way with some hex editing to create a maximum of 255 partitions, even manipulating the partition sizes
sorry, it's in Chinese and I'm kinda lazy to translate right now.
But ppl with knowledge in hex data should be able to figure out whats going on
ps: dang, it wouldnt let me post links, so change the commas into dots
