## Changes from original
|
|
|
|
### Alignment awareness
|
|
Original fat32format allocates only necessary size to metadata.
|
|
This isn't always aligned cluster.
|
|
Modified fat32format always round up 1 MiB.
|
|
|
|
NOTE: FAT32 is different from NTFS, metadata exists between start of the partition and first cluster.
|
|
|
|
### Immutable AUTORUN.INF
|
|
You can not open, read, write, rename, move or delete this on Windows OS.
|
|
Only re-format can delete this. (or delete from non-Windows OS)
|
|
|
|
NOTE: This behavior is undocumented.
|
|
It does not guarantee also be the same behavior in the future.
|
|
|
|
### Strict drive letter
|
|
Original fat32format accepts
|
|
|
|
fat32format.exe XYZABCDKGS!@#$%
|
|
|
|
This will format X: drive.
|
|
Modified fat32format deny this.
|
|
Only accepts
|
|
|
|
fat32format.exe X:
|
|
fat32format.exe \\.\X:
|
|
fat32format.exe \\?\Volume{GUID}
|
|
|
|
### Support volume label at format
