One of my Kaypro 10s has a bad case of the dreaded 'Spindle Stiction', ie. it won't spin up on it's own. I have learned to smack it in just the right place, to produce a radial moment normal to the plane of rotation, and then it spins up and boots. The first time I did this, I backed up the drive to floppies, so if the drive dies for good, no big deal. Allison, I believe, was the person who discussed this fairly common problem, some months ago. And since starting a drive with the handle of a big screwdriver can only be termed *abuse*, it's amazing that the poor thing works at all. But try this, in case there is something wonderful living on the HD, before you format it. (If in fact the no-boot is caused by stiction....) Cheers John
