2006-12-04Much simpler implementation of large virtual sector support, not needing ↵Jens Arnold
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
2006-12-03Add support (runtime detection) for 2048 bytes/sector filesystem.Miika Pekkarinen
Large sectors are enabled for iPod Video (including 5.5G) only. Might still cause FS corruption (however, unlikely), so beware! Based on FS#6169 by Robert Carboneau. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11651 a1c6a512-1295-4272-9138-f99709370657

2002-11-18Added longname handling to fat_remove().Björn Stenberg
Added proper 0xffff padding of last longname entry. add_dir_entry() now makes sure shortname is unique. Changed update_file_size() to use dir-as-file handling.
