Amiga error validating disk
If it is the drive at fault, you will need to open up your Amiga.
Get some isospropyl alcohol and cotton buds and give the drive heads a gentle clean.
If the drive is making unusual grinding noises you should probably stop using it until you’ve identified the problem.

This is a very simple and finally very cheap (5-10 eur) project: a very common chip (74LS06), a couple of resistors and diodes, a protoboard.
Good evening, I've opened it up and given it a clean.
I've cleaned both of the heads in the red circle area and everything seems to be moving fine (in the blue area) I'm no expert but it seems fine to me.
