Hi Bryce! Dont know how to do it... Now, I have cuted the case guts to fit an 3,5 drive disk, it is almost there need to buy an IDC connetor to make changes in order to connect the old cable to the new 3,5 floppy. Now is too late to try to fix the floppy drive... It will be replaced. I have bought this CPC knowing that drive was faulty on evilbay. I thought that a drive belt would solve the problem, but I dont know how to repair it. If I cant sell this, it will go to the bin can, it is useless to me. I am just selling it because it would be kind of handy for someone that knows how to fix it. It is sad to sent it to the trash bin
