    It's not a file system problem; FAT32 has a max partition size of 2TB so a 256GB drive should not be an issue.

    First check in Disk Management and see how the drive has been partitioned. Maybe there's only a 32GB partition with the rest "unused" or using a different drive letter, so that's why you're only getting 32GB when formatting. If this is the case, then you should be able to delete the smaller partition and create a new one that uses the full size.

    If that's not it, then there's a chance that it's a fake/knockoff USB drive. Some less-than-reputable manufacturers will simply print any number on the drive as its size, but only put much smaller flash chips in it. Sometimes they put firmware on it to make it act like a drive that's larger than it really is and ends up just corrupting any data that you try to put on it.

    try reformatting the usb drive, preferably to exFat if applicable. FAT can handle 256gb so you don't have to worry there. If you just use windows computers an NTFS format would be fine also.

    Windows format puts a limit of 32GB so use a third party app such as MiniAide Fat32 formatter that will format your 256GB drive for you.

    The drive has been set up a MBR instead of GPT. You need to delete the volume and then convert the drive to a GPT. This way the drive will see the total available storage capacity.

    Your problem is the wrong choice for format.  Do not use FAT 32--max size is 32GB.  Use NTFS.

    open cmd and use diskpart to "clean" the usb drive then u can use disk management to create the 256GB Partition. also a program called minitool Partition manager can do it for you.

    go into disk management and then take a screen shot and update your post.

    If you look at the first screen shot, you will see that the drive is format as FAT32.  With FAT32, the numbers used to determine how many memory sectors are on the drive is limited to 32 binary characters. This limits the size that it can see.  It runs out of numbers to be able to mark all the sectors on the drive, and so it can not see that these is anything beyond 32 GB of space.

    Reformat the drive with FAT 64 or NTFS and you will be able to see the rest of the drive.  This limitation (which also affects how much memory your computer can see) is the main reason they went from a 32 bit to a 64 bit version of Windows.

    what storage system is it using? FAT32 or 64 has inherent limitations
