- DIRECTORY PROBE COMMENTS
- by Phyrne Bacon
-
- DIRECTORY'PROBE prints the disk
- directory. It prints the track/sector
- of each directory block followed by
- the eight entries for that block, the
- beginning track/sector for each
- entry, the complete disk block chain
- for each entry, and all of the disk
- block chain fragments; that is, disk
- block chains that are not connected
- to the directory. Complete block
- chains and the fragments are
- optional.
-
- If the disk block chain of a
- directory entry does not have the
- length indicated in the directory,
- the message "WRONG LENGTH" is
- printed, which indicates that the
- file has been overwritten.
-
- Scratched files are indicated by ---
- or 0 in the PRG-column. Unused
- entries are indicated as beginning at
- track 0, sector 0.
-
- DIRECTORY'PROBE can be used with
- DISK'EDITOR to recover from a short
- new:
-
- pass"n:name" //without id.
-
- The command pass"n:name,id" erases
- everything, but the command
- pass"n:name" (without ",id") just
- erases block 18-1 and clears the BAM.
- See Disk Directories II: Recovering
- from pass"n:name".
