Is there some trick I can use to use this USB drive without formatting it?

    It is is a 4TB USB drive. I formatted it in Windows and used GPT dynamic disk so I can have 1TB & 2TB NTFS partitions, and then also a 1TB FAT32 partition for ps3 games. Like an idiot I filled it almost completely with data before plugging it into my ps3 thinking the FAT32 partition would "just work" but it not detected. I can't even get the drive to show up at all, even using the NTFS option in mmCm.

    I'm thinking I might just have to start all over and let the ps3 do the formatting, but not sure how that will work with the drive being 4TB and FAT32 has 2TB limit. Also, is there a way around the 4GB file limit in windows? I know it is possible to put files >4GB on FAT32 because this works when sending files over FTP from NTFS on PC to FAT32 on PS3 thru an ethernet cable. Thing is, that usually caps out around 15-20MB/s speed and if I could do it natively in Windows I'd be looking at more like 100-150MB/s speeds.

    drives must be in mbr format. you can change from gpt to mbr without formatting with easeus. I'm not sure if the ps3 can read multiple partitions though. 4GBs is the limit with fat32. it's a limitation of the file system, so you can't get around it.

    that - I don't know. normally, the ps3 shouldn't be able to read gpt, so maybe it's not a restriction with ftp?

    I was referring to ftp to the internal drive which is probably mbr.

    it should ftp to the internal hdd without issue. I believe the internal hdd has a linux-based file system that I can't remember the name of. I think it's an acronym though.

    When you say pseudo-linux does that mean it is proprietary or would it be possible to format a USB drive to that and use Linux or a 3rd party app to do 100+MB/s file xfers?

    4K sectors in new HDDs are done physically now instead of spoofing. So no 3rd party app will allow you to make MBR partition larger than 2.1TB. And crappy part is not even with multiple partitions. So you lose the extra space.

    Luckily I got my 5TB before Seagate implemented the physical 4k sector. Best you can do is use ps3netsrv, or FTP to internal. Hardwire between PS3 and PC, and should get decent transfer times. But still bottlenecked by PS3s limitations.

    2.1TB is enough, but can I set it up so the remaining space is ntfs or something so I can use for PC backup? Its not a new drive it is a Lacie Porsche 4TB drive so it may have the same 4k sectors as your Seagate.

    Try using Easus Partition Master Free. Initialize as MBR, and try to format the whole drive as 1 Primary partition to either FAT32 or NTFS, and set as active. If it won't let you, and leaves the rest of the space unallocated. Then you know it's not possible.

    If that is the case, I would just keep it connected to PC and use ps3netsrv to stream your games from there.

    The internal hdd relies on a freebsd implementation of UFS2 for GameOS.
    It uses 512 bytes sectors & the UFS file system is encrypted using the per console specific eid_root_key.

    A UFS2 driver can be used on Linux/BSD/Windows/Mac to read/write from/to the UFS2 file system using the extracted eid_root_key.

    Excerpt from psdevwiki:
    Currently on Windows, there is only a ps3 hdd reader available with no way to write to the device. However, it would only be a matter of finishing the work 3141card started to enable writing or even port a UFS2 driver...
    Maybe some day a dev will finish the job.. I have wanted to do it for a while but am far too busy with other projects atm.
