I had received three emails on January 17th that required me to do a little research. In the interim, an accident with FDISK caused me erase my C drive. While I have a daily backup, I lost those 3 emails.

So if you emailed me on the 16th or 17th and didn’t get a response, I apologize but I don’t have your email address anymore.

If you have an unanswered question from me, please reach back out.

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.

A big THANK YOU to all of those who have sent in software from the Missing TRS-80 Model I/III/4 Software page!

As always, if you have any of the items on the list, please Contact Me.
