  1. Hi, I have 64gb usb flash drive and was working, when I put some files on it mixed all music files and didn't open at all after that I wanted to delete but couldn't delete I thought there is only one option that was formating usb flash drive, I formated my usb and lost everything.
    And I wanted to use again but my computer asked me to format it otherwise can't use it then I did again but couldn't use it, computer don't open it, when I checked on properties its show there is not any empty space, how can it be full while it has nothing on it?
    Is there any one can help me how can I use it again?

    the process is to
    • delete the partition
    • create another
    • then use the command prompt to reformat the device

    Formats a disk for use with Windows XP.
    FORMAT volume [[B]/FS:file-system[/B]] [/V:label] [/Q] [/A:size] [/C] [/X]
    FORMAT volume [/V:label] [/Q] [/F:size]
    FORMAT volume [/V:label] [/Q] [/T:tracks /N:sectors]
    FORMAT volume [/V:label] [/Q]
    FORMAT volume [/Q]
      volume          Specifies the drive letter (followed by a colon),
                      mount point, or volume name.
      [B]/FS:filesystem[/B]  Specifies the type of the file system ([B]FAT, FAT32, or NTFS[/B]).
      /V:label        Specifies the volume label.
      /Q              Performs a quick format.
      /C              NTFS only: Files created on the new volume will be compressed
                      by default.
      /X              Forces the volume to dismount first if necessary.  All opened
                      handles to the volume would no longer be valid.
      /A:size         Overrides the default allocation unit size. Default settings
                      are strongly recommended for general use.
                      NTFS supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K.
                      FAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
                      (128K, 256K for sector size > 512 bytes).
                      FAT32 supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
                      (128K, 256K for sector size > 512 bytes).
                      Note that the FAT and FAT32 files systems impose the
                      following restrictions on the number of clusters on a volume:
                      FAT: Number of clusters <= 65526
                      FAT32: 65526 < Number of clusters < 4177918
                      Format will immediately stop processing if it decides that
                      the above requirements cannot be met using the specified
                      cluster size.
                      NTFS compression is not supported for allocation unit sizes
                      above 4096.
      /F:size         Specifies the size of the floppy disk to format (1.44)
      /T:tracks       Specifies the number of tracks per disk side.
      /N:sectors      Specifies the number of sectors per track.
    Unless you need to mount the device on a Macintosh or Linux, use /FS:NTFS
