- NAME
-
- check - Check AmigaDOS disk structure for errors
-
- SYNOPSIS
-
- check volume [show]
-
- DESCRIPTION
-
- Check scans the filesystem specified by "volume" for inconsistencies.
- All errors in the file structure, including any found in the
- AmigaDos redundancy information are reported.
-
- No attempt is made to correct the errors. A program like "sectorama"
- or "diskx" can be used to edit disk blocks using the information obtained
- from Check.
-
- If Check finds an error, it will ask for permission to continue.
- Responding with a "n" will cause the current file to be skipped.
- A "y" will cause Check to attempt to continue as if the current
- block were correct. (In general, "n" is a better response).
-
- The "show" command option will cause check to attempt to analyze
- any blocks in which errors are found, in order to give an indication
- of whether or not the block is seriously damaged.
-
- At the end of the disk scan, Check will prompt to check the
- disk bitmap. Usually, this is a good thing to do. Certain
- disks however, such as "kickbench" disks, will have a lot
- of information here that isn't useful. The result of a bitmap
- scan is a list of 1) blocks that are in the bitmap but weren't
- found (these will not cause serious problems, but may be lost
- data from a previous problem) and 2) blocks that are
- found but not in the bitmap (these WILL cause serious problems
- because these blocks can be written over freely by AmigaDOS.
-
- Note that if you respond "y" to the "Continue [y/n]" prompt
- at any time, you may come across more blocks of the second
- type described above.
-
- After the bitmap scan is complete, Check prompts for the
- block analysis phase. During this phase, enter either a decimal
- block number, or carriage return to quit. Check will attempt to
- classify the block into the proper block type.
-
- Check maintains a log file in RAM:check.log. This log file is
- closed after the bitmap scan, so you can refer to it during the
- block analysis phase (using another AmigaDOS CLI).
-
- FILES
-
- RAM:check.log - Log file produced by running Check

- BUGS
-
- None known, however, Check will not work with Fast File System disks.
- Has not been tested with partitioned disks, but has been tested
- on a 40M hard disk, vd0:, and floppies.
