formatting a drive says required parameter missing -

Question

Tuesday, February 2, 2016 9:19 PM

Here is my command: format /FS:FAT32 /V:FAT32

Anyone see how to correct this adding a required parameter of a dash (-) ?

I will continue searching for examples. Haven't found any yet.

update: disregard. I called WD customer service and they had me do it using disk management. That is a better idea anyway.

update 2: The only 2 choices are NTFS and exFAT. Is exFAT compatible with FAT32?

For volume needs to be first I would say looking at the help for the format command

"Formats a disk for use with Windows.

FORMAT volume [/FS:file-system] [/V:label] [/Q] [/L[:state]] [/A:size] [/C] [/I:state] [/X] [/P:passes] [/S:state]
FORMAT volume [/V:label] [/Q] [/F:size] [/P:passes]
FORMAT volume [/V:label] [/Q] [/T:tracks /N:sectors] [/P:passes]
FORMAT volume [/V:label] [/Q] [/P:passes]
FORMAT volume [/Q]

  volume          Specifies the drive letter (followed by a colon),
                  mount point, or volume name.
  /FS:filesystem  Specifies the type of the file system (FAT, FAT32, exFAT,
                  NTFS, UDF, ReFS).
  /V:label        Specifies the volume label.
  /Q              Performs a quick format. Note that this switch overrides /P.
  /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.
  /R:revision     UDF only: Forces the format to a specific UDF version
                  (1.02, 1.50, 2.00, 2.01, 2.50).  The default
                  revision is 2.01.
  /D              UDF 2.50 only: Metadata will be duplicated.
  /L[:state]      NTFS Only: Overrides the default size of file record.
                  By default, a non-tiered volume will be formatted with small
                  size file records and a tiered volume will be formatted with
                  large size file records.  /L and /L:enable forces format to
                  use large size file records and /L:disable forces format to
                  use small size file records.
  /A:size         Overrides the default allocation unit size. Default settings
                  are strongly recommended for general use.
                  ReFS supports 64K.
                  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).
                  exFAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
                  128K, 256K, 512K, 1M, 2M, 4M, 8M, 16M, 32M.

                  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.
  /P:count        Zero every sector on the volume.  After that, the volume
                  will be overwritten "count" times using a different
                  random number each time.  If "count" is zero, no additional
                  overwrites are made after zeroing every sector.  This switch
                  is ignored when /Q is specified.
  /S:state        Specifies support for short filenames (enable, disable)
                  Short names are disabled by default
  /I:state        ReFS only: Specifies whether integrity should be enabled on
                  the new volume. "state" is either "enable" or "disable"
                  Integrity is enabled on storage that supports data redundancy
                  by default.
  /B[yteAddressable][:state]
                  NTFS and ReFS Only: Enable direct access storage (DAS) mode
                  for this volume.  In direct access storage mode the volume is
                  byte addressable.  In DAS mode, the volume is accessed via the
                  memory bus for most of the files boosting IO performance,
                  bypassing the storage stack.  NOTE:  File system mini fileters
                  won't see paging IOs for the files being accessed in DAS mode.
                  A volume can be formatted with byte addressable mode only if
                  the hardware supports.
                  State can specify "enable" or "disable"

So;

format G: /FS:FAT32 /V:FAT32A

from an admin command prompt, does that work?

Why not use Diskpart to format the partition?

How big is the drive? If the drive is over 32GB, FAT32 will not work. You have to use one of the other formats.

You can still create a 31GB partition on a larger disk for FAT32. The rest of the space is a waste however.

Appears to me you are missing the Volume to format. So;

format E: /FS:FAT32

from an admin command prompt works for me to format my E: drive FAT32. Enter format /? for help.

I attempted this statement.

format /FS:FAT32 /V:FAT32A G:

The result is "Enter current volume label for drive G:FAT32"

I typed in fat32. Then it says an incorrect volume label was entered for this drive.

WD support doesn't understand command prompt, and disk management doesn't understand FAT32, only offering NTFS and exFAT.

I attempted using my Vista computer also, but it says some sort of device driver needs to be installed and I could not get the driver from wdc.com
