Yes- I too have this trouble.  All along I thought that it was just me who was
giving every disk inserted an extra nudge...  I just ordered the Free Spirit
1541/71 Drive Alignment Kit- I'll let everyone know how well that works.
I'd like to check the drive motor speed accurately (an old C-64 copy program
tells me its 309.25 rpm, but I doubt that it's reliable.)

Does anyone know where the drive speed potentiometer is on the C128D's 
internal 1571 drive?  If not, how about on a regular 1571 (maybe that'll
help...)

Thanks
