Does anyone know of a low level formatting program for the TRS80's Model 4/III? Trying to see if I can revive an external RS 15MB HDD

I just read your post again, I don't think it's drive.Actually no, GAT error can be a good thing.
This tells me several things.
You install drivers or use this Tandy install program?
Format with what? And says writing directory..........?
Then a sysgen? Followed by RESET?
Please let me know and I will help you out.
If you understand manual install if might be of benefit to download rshard6. Roy wrote it to overcome RS supplied driver shortcomings.I used the TRSDOS 6.2 Hard drive setup program. Mainly Hardgen/bas. which does everything for you. But was thinking maybe I should try to do it manually. Which I am familiar with using.
That is how I set up the Lo-Tech-IDE. Which works fine BTW.
Only other questions I would have is those 3 wires soldered in correct place? If you think someone else already worked on this in past verify everything.
Yes I saw that. But that was the larger 8X300 board. I found where they go on the smaller board which I have the WD1000-TB1 and have connected the 3 wires already to it already.
And I did as he did and used a connector so I can seperate the circuit board from the wiring harness on the chassis. It wasn't to hard to locate the solder points.
