My SY77 disk drive does not work. I have taken the following steps.
1. I replaced the broken drive band with a rubber band and it now spins the disk but I get a "bad disk error" .
2. I cleaned the drive head per Yamaha's instructions but I still get the same error message.
3. I verified that both disks are readable on Win95 and they were original formated on the SY77.
I have been unable to find any useful information on the Yamaha web site. Are there any manual adjustments on the drive that might be out of spec. ie: speed of drive motor? Can a Mitsumi/Newtronics 3 1/2" drive replace the Newtronics (original drive/connector)? Any help is appreciated.
