[comp.sys.mac] Pro 80ii/I Drive

Hi folks.  This note is to see if anyone else has had a similar experience with CMS hard drives and if there's anything I can do about it.  I bought a CMS Pro 80II/i (80 MB) hard disk a year and half ago, with an original Mac II.  The drive has since developed a reluctance to boot up.  Once the drive is going, it works fine (and quickly), but the problem is getting it started.  After fiddling with all sorts of software solutions for months, each telling me nothing was wrong with the drive, I noticed that a


 swift whack to the side of the Mac would get the drive to start spinning.  So everytime I boot, I need to bump or jar the drive to get it going!!!  Clearly, I'm long out of warranty, and the CMS techs tell me that I can get a new USED drive for $300 (the guy also told me that the drive might also be useful as a paperweight), if I want.  
        Has anyone else had a drive do this?  If it is a friction problem with the drive motor, is it something I can get into and fix?  I'd appreciate any feedback.  Thanks,
        Mark Wendell

My external CMS Pro 60 had a similar problem.  The fuse inside the case
turned out to be dirty.  Just handling it to check it with a flashlight
(visually and testing the current) cleaned it off enough that it worked.

There is also a drive speed screw that controls the speed of the motor.
The place where I bought my drive said that sometime they work their
way out and the motor is set too slow.  Screwing it out slows it down
and screwing it in speeds it up.
