    v3 v4  
    11Starting from r172, the disk access is denied (ERROR_VOLUME_DIRTY is returned) on DosOpen and DosFindFirst. So, the IFS won't allow to access disk if it is dirty. A command line option "/readonly" is introduced. If it is specified, the IFS behaves the old way. The dirty flag can still be toggled by the f32stat utility.

    3 PS: I uploaded the new alpha8 of fat32.ifs: ZIP archive: ftp://osfree.org/upload/fat32/fat32-0.10-r174.zip,  WarpIN package: ftp://osfree.org/upload/fat32/fat32-0.10-r174.wpi. Note than it contains more changes: 1) preliminary > 2 Gb file support. Files of size up to 4 GB are now supported. But seek beyond 2 GB is still not working, because FS_CHGFILEPTR is called instead of FS_CHGFILEPTRL (so, the file pointer is truncated to 32-bits) 2) support for 64 KB clusters is introduced. But there are some bugs introduced, so ReadSector may sometimes read zero bytes.
