- new wipe tool
- ability to optimize virtual disk containers combining wipe with imgclone tool
- fixed a small help-bug in mkvdisk.py

imgclone tool added

v1.0.28

Update README.MD

Faster FAT space mapping and enhanced floppy formatting

Improved speed in mapping FAT free space and formatting floppy images

v.1.0.26: Fixed and enhanced

- exFAT code is now dramatically faster in mapping free space (particularly when volume is almost empty)
- test tools updated (new fat_mkfs code), added VHDX test
- fixed a bug in new FAT(12,16) formatter

v.1.0.25

better *_mkfs code

- clusters computation is now greatly faster in many scenarios
- more accurate floppy media byte detection
- mkfat --fat-copies can set the number of FAT tables to write

v1.0.22

Some bugs were fixed

v.1.0.21

MBR supports 4K sectors

Fixed code that prevented 4K sectors in MBR partitions up to 16 TB

v1.0.20

Fixes and large enhancements

Highlights:
- added 4K sectors support in VHDX images
- FAT format code merged into a single fat_mkfs function
- 128K and 256K clusters allowed with 4K sectors (FAT)
- really working cylinder alignment for new partitions
- partition type code is now correctly updated in MBR after format
- better compatibility switches with traditional DOS/Windows FORMAT

disk.py:
- new type() member returns a string type name

exFAT.py:
- VBR checksum is checked at boot sector from disk initialization

FAT.py:
- mostly cosmetic changes in some member names
- FAT() initialization accepts and uses disk sector size

gptutils.py:
- pack() honours sector size

mkfat.py:
- new single fat_mkfs function for all FAT12/16/32 formats with better documentation
- support for 4K sectors
- simplified cluster auto-selection (FAT)
- enhanced CHS geometry handling
- return codes and optional messages
- better FAT media byte handling
- duplicated format app tool (__main__) is removed from here

partutils.py:
- LBA-CHS conversions moved in utils.py
- new (definitive?) partition type code calculator
- 4K sector support
- partitioning algorithms revised to do proper cylinder (old DOS) or MB alignment, and to honor disk geometry whenever possible

scripts/mkfat.py:
- new options for FAT tuning (FAT32 limits, FAT12 exclusion with HDDs, no 64K clusters in old systems)
- partition type code is updated in MBR according to applied format

scripts/mkvdisk.py:
- added 4K sectors support (VHDX)

utils.py:
- LBA-CHS conversions moved from partutils.py

vdi/vhd(x)/vmdkutils.py:
- added 4K sectors support (actually effective for VHDX only)

vhdutils.py:
- removed block alignment check in BAT (Windows does not care, and blocks could be unaligned in some scenarios)
- parent's timestamp is checked no more (like Windows 11)
- fixed a bug in dwMaxTableEntries calculation
- fixed a bug in parent timestamp assignment
- fixed a bug in parent's locator encoding

Volume.py:
- added 4K sectors support
- copy_tree_in can optionally convert file names in upper case passing uppercase=1

v1.0.14

Adapts GPT partition handling to Windows 11 requirements.

v1.0.13

Bugs in vhdutils fixed and enhanced BAT self-test
