Re: important! Windows 10 doesn't allow fat 32 formatting for flash drives for the moment

You can get the list of options for the command version of the format program by typing “format /?” at the command prompt. Below is the result from the latest version of Windows 10.

 

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

  /TXF:state      Specifies txf is enabled/disabled (enabled, disabled)

                  TxF is enabled 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.

  /DAX[:state]    NTFS Only: Enable direct access storage (DAX) mode for this

                  volume.  In DAX mode, the volume is accessed via the memory

                  bus, boosting IO performance.  A volume can be formatted

                  with DAX mode only if the hardware is DAX capable.

                  State can specify "enable" or "disable".  /DAX is considered

                  as /DAX:enable.

Hi

I agree  about players providing their own software. They could simply auto format flash drives on insertion, with a prompt of course. The problem with the companies providing their own software though is that they would almost certainly limit that software to the operating systems they perceive as popular, meaning windows and possibly mac. They would probably have an app for your smart device. That’s great except then every company which manufactures players would have their own app for their own players, resulting in multiples of the same app by different companies which all do the same thing. Better to have an open source app which multiple companies support if they’re going to go that route. Put it on git hub or something, and have it buildable on whatever OS you use. Pre built ones for windows, mac and maybe Linux as well, and app packages for android and IOS, just to cover all the bases. They wouldn’t even have to support it directly, just work together to develop it then give it to the community, with maybe an email address for help.

Thanks

Kendell Clark

NTFS is harder on flash memory than fat 32. That's why you almost never get flash drives in NTFS, unless they are really large ones like 128 gb and up.
The reason NTFS is harder on flash drives is because these things only have a limited number of writes. NTFS is a journalling file system, meaning it writes to the media more often than would happen as fat 32.
In addition, NTFS supports permissions, which is often not applicable for flash drives. File permissions could actually create problems on those when you transfer them between computers.
The only time you might want to consider formatting a flash drive as NTFS is if you are going to copy a file more than 4gb in size to the drive.
