usb partitioning


I was installing BT4 to a 4g flash drive and some were between defining partitions and setting up the file system i decided that i messed up and that i would clear the key, delete the partitions and do it later. But when i was doing it later, while in fdisk i noticed that my 4g flash drive was now only showing as 2g, any thoughts?

    it seems that the other part of your 4g flash drive is unallocated, or may be it is formatted on different file-system format, you can reformat your flash drive using gparted. note before formatting your flash make sure you resized the current partition adding the unallocated spaces.

    hope it helps.

    If you want to clear EVERYTHING from your drive, you can run the following:

    dd if=/dev/zero of=/dev/yourusbdrive
    obviously replace yourusbdrive with hdb or sdb, however your version of Linux reads it..

    That's probably the easiest and best option as per what Cody said. dd is lovely, then just mkfs.fstype /dev/device :>
    or fdisk. whatevers better for you.

    I do believe that if you use fdisk -l /dev/yourusbdrive, it will show you all the partitions on your stick, even the empty spaces.
