I have lots of Amiga formatted 720kb floppies with Amiga software inside. They come from different years and different people. Some have been preserved well and some poorly. In between there are perfectly good disks, disks with bad sectors, disks that are nailed in their case and disks even with mold.

To check the working ones and throw away the dozens and dozens that don't work I would have to check them, only that checking them by inserting them into an original Amiga drive exposes it to making it unusable if I were to insert a blocked disk or one with a moldy surface, these drives are very rare and expensive

So I wanted to use the cheap 1.44 PC drives to do this. Obviously the PC isn't able to interpret what's inside the drive... but I don't think it's necessary either. Is there any software that does a sort of RAW reading of the disk surface to see if the disk is spinning, has problems, has an unreadable surface, etc.? Or does it necessarily have to interpret the contents of floppy disk files?

Thank you.

It would help if you included "Amiga" in the title.
There is a guide on reading Amiga floppies on a PC. The cheapest solution would be using 2 floppy drives with adfread. Other solutions include building a floppy controller like Greaseweazle.
It's also possible to convert a PC floppy drive to use in an Amiga (in case yours gives up), not sure what is the authoritative way of doing this as it varies depending on the model of floppy drive.

I have been using FORMATQM which I saw Adrian from Adrian’s Digital Basement use. He has a great video on this.

  • I physically inspect each disk before inserting it. If there is mould, I throw it away.
  • Using FORMATQM, I format the disk and set it so that if there are any bad sectors, it fails and I throw the disk out.
  • Ideally, I would clean the disk drive every few disks, because it will collect whatever junk is on those disks on the heads. I have not done it that often, but that is the aim.
