fat95 - Win95/98 compatible FAT filesystem handler for AmigaOS. Fork of disk/misc/fat95.lha.

CHANGES IN 3.23 (19.05.2026)
============================

This release brings several reliability fixes, contributed by Stefan Reinauer. Thanks!

- File position is now correctly advanced after a short (partial)
  write, preventing data corruption on subsequent writes to the same
  file handle.
- SCSI READ10/WRITE10 commands now correctly clamp the block count to
  16 bits; previously, large I/O requests could silently transfer fewer
  blocks than requested.
- I/O retries are now aborted if the disk was swapped during a retried
  read or write, preventing silent data corruption when media changes
  mid-operation.
- The ".." (parent) directory entry for subdirectories created under
  the FAT32 root now correctly stores cluster 0, fixing fsck.vfat
  complaints on FAT32 volumes.
- The free-cluster scan in ExtendChain is now bounded to avoid an
  infinite loop on a corrupted or full FAT.
- FAT16 free-cluster counting during mount is now ~50% faster on 68000,
  by scanning the raw FAT buffer directly.

Purpose
=======

"fat95" is a DOS handler to mount and use Win95/98 volumes just as if they were
AMIGA volumes.

System requirements
===================

* every AMIGA, OS 1.3+ (OS 2.0+ for full functionality)
* a suitable device file for low level disk access, like the
  mfm.device for floppies, compactflash.device for CF in PCMCIA

Features
========

See fat95.guide for full documentation.

* Workbench and applications support
* Diskchange autosense
* Format type autosense: FAT12, FAT16 and FAT32
* MBR and GPT partition table support
* Simple LINUX style partition selection or manual definition
* Up to 4 GBytes of partition size for FAT16
* Large harddisk support via TD64 or direct SCSI
* Long filenames (up to 104 chars for now)
* Inquiry, read, write, and maintenance access
* Built-in error check utility
* Disk formatting using the OS 2.0+ format command
* MS-DOS 8.3 downward compatibility
* User definable language and code page
* Date range Jan 1st, 1980 through Dec 31st, 2107
* Extended datestamp support: creation date and time, last accessed date
  (written automatically, readable as file comment text)
* Volume serial number as name for unnamed volumes
* Automatic directory optimization
* Written entirely in assembly language
