Need help repairing floppy drive

I also read your previous topic and seeing your question here I strongly suggest you to get someone helping you physically opening the machine that knows what he is doing. Not only you are risking breaking all plastic notches but also risking damaging the machine beyond repair.

Best case scenario is that only a drive belt needs te be replaced.
Worst case scenario is that the drive needs to be replaced, in that case please check this howto to see how familiar you are with this kind of repairs.

I ment these reactions :

This gave me the feeling that not only on a MSX way, but also on a troubleshooting way you're not an experienced repairman. I might be mistaken.

To open up your WSX, just unscrew the screws from the bottemplate. Then with a smal flat object (small screwdriver or such) you can very gently click the notches on these places (see picture) and open up the machine. It is best to do the side of the diskdrive as last since you need to bend the housing over the diskdrive eject button.

Better not to use a screwdriver to open the case. Buy a kit for opening mobile phones and tablets. It contains special tools made from hard plastic to open tightly closed cases. These tools don't leave scratches on the computer's case.

Ok I got it open successfully, and made my way to the floppy drive belt without issue. The belt appears to be in good shape and is intact. When the drive tries to read a disk it will make an abnormal noise when reading a disk.

Sorry I just edited my post.
