- Files of this type and auxiliary type contain blocks that should not be used
- by the file system.
- _____________________________________________________________________________
-
- Files of type $01 contain physical media blocks that should not be used by the
- file system. A utility program can scan a disk looking for blocks that cannot
- be read and can then synthesize a file containing those blocks. Such a file
- should have type $01.
-
- Files of this type should not be touched. If a program finds one, it should
- leave it alone. If you must delete such a file, be sure to double-check with
- the user.
-
- Versions of ProDOS 8 prior to 1.8 can cause file system corruption (on ProDOS
- disks, of course) if you attempt to delete a file of bad blocks, so be sure
- not to do this. Attempting to delete a bad blocks file is only marginally
- reasonable for people manually attempting disk repair. A bad blocks scanning
- utility does not need to delete the old bad blocks files before creating new
- ones; it should just create new files as necessary. Apple Computer, Inc.,
- does not support deleting a bad blocks file.
-
- The auxiliary types for this file type are reserved; any files created of type
- $01 should be created with auxiliary type $0000.
