SFS\00 and SFS\02 support other block sizes but only 512 bytes should be used since it is slower with larger blocks. JXFS only supports 512 block size. Recovery tools are located in Media Toolbox in the SYS:System drawer. Always have a backup.

| Comments | Legacy file system, not recommended for AmigaOS 4.x due to lack of long filename support. Can be used for bootloader partition in AmigaOS 4.x only setup. | Current file system, bootable, can be used with AmigaOS 4.x, recovery tools available, not as fast as SFS, requires validation if disk error. | Current file system, bootable, can be used with AmigaOS 4.x, some recovery tools available.
