INT 24 DOS error message

[JoeG]

I'm trying to revive a CompuAdd laptop that has DOS on it. When these were originally sold, they came with Windows 3.1 installed. What's holding me back from reinstalling Windows 3.1 is that I can't get the floppy drive to work. I always get a Abort, Retry, Fail message when trying to access the floppy. I do on occasion get the Fail on INT 24 error message from DOS when trying to format a floppy disk.

In a previous post, I mentioned that the floppy that came with the laptop had a bad capacitor that I replaced. That didn't help. The replacement floppy drive I purchased also didn't make any difference. I still can't get the drive to pull a directory, or format a floppy. So today I ordered a 34-pin to USB floppy adapter from Amazon. I want to check these drives outside of the laptop.

Has anyone run into this issue with a perceived faulty floppy drive that always gives errors even when the floppy has been replaced with a hopefully working floppy drive?

Thank you

Joe
