* Much simpler implementation of large virtual sector support, not needing ↵Jens Arnold2006-12-04
| | | | | | larger sector buffers and not touching file.c at all. secmult is simply used to normalize all sector counts to 512-byte physical sectors. * Moved MAX_SECTOR_SIZE definition to config-*.h, and enabled it for iPod Video only. MAX_SECTOR_SIZE now only enables checking for alternate disk layouts due to sector size (as iPod Video G5.5 is presented as having 2048-byte _physical_ sectors to the PC). Large virtual sector support in fat.c is always enabled. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11659 a1c6a512-1295-4272-9138-f99709370657

* Add support (runtime detection) for 2048 bytes/sector filesystem.Miika Pekkarinen2006-12-03

* Bugfixes: (1) add_dir_entry() always appended new entries, although the ↵Jens Arnold2005-04-22
| | | | | | code intended to reuse deleted entries. New code reuses deleted entries whenever possible. (2) If the code could not extend the dir to append new entries (FAT16 root dir or disk full), it failed because of (1). (3) Even if reuse had worked, it would never have reused entry 0. (4) Shortname char 0xE5->0x05 replacement to avoid treatment as free entry was done for all chars although it should only be done for the first. The 0x05->0xE5 replacement on read was missing altogether. (5) Obey directory size limit (65536 entries == 2 MB). Improvements: (1) The (undocumented) flags used by WinNT derivates to store the case of a shortname's name and extension part are now supported for reading. (2) smaller code size. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6332 a1c6a512-1295-4272-9138-f99709370657
