    I've got 4 USB sticks lying around and only 1 of them reads. Searched for the better part of a day to find out why.

    Ultimately, Discovered what the problem was. You absolutely must use a MBR. As soon as I did that, all my USB sticks read just fine on the PS2 (Even Kingston). They were indeed set to GPT.

    To do this:

    Run diskpart
    Find your USB, select disk #
    Disk Selected? now 'clean'
    Now 'convert mbr'
    Close disk part.
    Run diskmgmt.msc
    Find your USB. Format it as FAT32.

    Should read just fine now in your PS2.

    Why running diskpart and next diskmgmt when in diskmgmt You will also "convert" GPT to MBR? ;p

    I see in my imagination many peoples who don't understand device recognition, formatting their HDD. :D And... why formatting partition to FAT32 when someone already have FAT32 on it?

    This is true. You can just convert in diskmgmt.msc as well, I'm just used to doing it in diskpart.

    I actually didn't find any references to MBR/GPT in my original search, Was a guy on Discord that suggested GPT was issue. So hopefully this makes the information easier to find.

    There is many formats of partition tables but only MBR is supported by old software. We could blame for it mostly Windows tools which they don't recognize more than one partition on removable media but for some reason creating MBR on them. World would be better place if Windows doesn't create any partition table on such devices, leaving of course only file system table (i.e this is the reason why peoples writing tiny disk image into MicroSD for VITA2SD, resize fs and fix fs...).

    if diskpart and similar tools are too archaic for you,good free app with nice GUI is minitool's partition wizard.also,HP USB disk storage format tool is standard for ever,and because USB flashdrive's are basically SD card with usb connection built in, SD memory card formatter is industry standard.all of them are free to try out.

    No... Pendrives, SD cards etc. are devices with NAND/3DXP RAID with quite complex firmware to managing blocks. They are tiny, autonomic computers, they are one and the same family, including SSD's. :P


    Best free app for partitioning is in my opinion GParted, build-in in mostly Linux distributions.

    i've said basically,especially in regards to applicable formatting software.that means that sd memory card formatter can be used for restoring pendrives same as sd cards.

    I actually just tried to convert some of my remaining USB sticks to MBR in diskmgmt.msc -- The option actually does not exist. Convert to Dynamic/GPT exists for the HDD's I've got in there. But plugging in a USB and right clicking gives no such option.

    The diskpart way will do it for sure.

    This is my favourite :)
    Everytime i need a tool for that it comes to mind the name of it because the fact it was made by Hewlett Packard
    I use to forget the name of it, so im like... "hmmm, how it was named that tool from Hewlett Packard ?"
    Then i search in google for random names like HP + USB + MBR and i find it that way :D

    is there an app to convert mbr to gpt and vice versa without formatting? disk management in windows requires a format. easeus can do so without a format, but now that option isn't a part of the trial version as I discovered a few months ago.

    thanks. I got some error about space when using that app. I fixed it by deleting the partition, creating a new ntfs partition, and trying again. I took the data off before testing; alright, it seems to work with data present.

    i never lose data no matter what to what i was converting in partition wizard.i know there's risk in doing it,but personally never had any issue,and i'm using it since 2010ish (for sd card partitions in first couple of sony ericcson xperia phones to try to run android on them).
