Lawrence Kesteloot has updated his TRS-80 Tool with a new subcommand to the option to focus on bad sectors of a disk image.
The sectors command displays a table of the sectors in a floppy disk. The columns are the sectors and the rows are the tracks. For each sector a character is displayed with:
- – No sector.
- S Single-density sector.
- D Double-density sector.
- X Deleted sector.
- C CRC error (ID or data).
- ? Missing sector.
Use the –contents flag to also show the contents of the sectors.
The new –bad flag lists all sectors that are missing or that have a CRC error, as well as which file (if any) is on each bad sector. Can be combined with –contents to also show the contents of the bad sectors.
The instructions page can be found at https://www.my-trs-80.com/tool/#sectors, executables can be downloaded at https://www.my-trs-80.com/tool/#installation, and the source can be downloaded by choosing DOWNLOAD ZIP from https://github.com/lkesteloot/trs80.
