Hi people:

I have great pleasure to let you know that my 620īs disk drive is "alive" again.The problem was really the spin motor belt.The first belt that I have installed didnīt have the exact dimmensions ,so the drive was not able to recognize the right speed.I have found on WEB that this belt is also used in a similar drive assembled in old computers MSX Panasonic Turbo-R model.Since you get the right belt you have great chance to fix the drive.Iīm able to help you to find this belt.

Thanks anyway
