    Flash drive displaying WAY smaller than usual capacity

    When I insert my Lexar 16 GB flash drive and go into the disk utility, it says that it is only 1/2 a MB! I also tried to go into GParted and it said the same thing. I tried formatting it again but that still didn't work. For some reason, my other computer (mac) does read the capacity as 16 GB. Has anyone ever encountered this problem or could help me with it? Thanks in advance!

    On you mac, what is the filesystem of the flash drive? FAT32, NTFS?

    I used FAT32, as I couldn't see an NTFS option.

    Oops, I forget to mention that I tried reformatting my flash drive on my mac, and I used FAT32.

    Can you try reformatting it in a windows system? Not sure though but if I remember correctly there are some issues regarding formatting flash drives in mac with the FAT32 option.

    Sorry, no can-do. I don't have a windows computer, or easy access to one. Thanks for the suggestions though. Anything else that I could try?

    Plug it in Linux.
    In the terminal,
    Code:
    sudo fdisk -l
    If should have an output like this:
    Code:
    Disk /dev/sda: 500.1 GB, 500106780160 bytes
    That is my primary hard drive. If your flash drive is listed there and it is detected as 16GB, continue.
    I'll assume your flash drive is /dev/sdb. Your going to format it again here.

    Code:
    sudo fdisk /dev/sdb
    You'll enter the fdisk utility to edit the partitions.
    Press d and hit enter to delete the partition.
    Press w and hit enter to write changes.

    Repeat:
    Code:
    sudo fdisk /dev/sdb
    Press n and hit enter to create new partition.
    For partition type, hit enter to accept the default.
    For partition number, hit enter to accept the default.
    Hit enter again to accept the default for First Sector.
    Hit enter again to accept the default for Last Sector.
    Press w and hit enter to write changes.

    List the partitions:
    Code:
     lsblk
    You should see something like this:
    Code:
    NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
    sdb      8:16   1   7.5G  0 disk 
    └─sdb1   8:17   1   7.5G  0 part
    We need to format the /dev/sdb1 to FAT.
    Code:
    sudo mkfs.vfat /dev/sdb1
    It should be done now.

    Didn't even get past the first step. It came up with this: unable to read /dev/sdb: Invalid argument. Should I try reformatting it on my mac again?

    O.o mind blown. You can try it again but I think it will still be the same.
    Anyway, I'm not familiar with mac utilities but try searching for apps that can format flash drives using a Mac. Try to avoid using the default disk utility.

    Okay, thanks for your help anyway. If I manage to get my flash drive properly recognized then your scripts will definitely come in handy.
