Re: Profile Drive issues (of course)

Hi,

You may look at the Head Break, wich may be blocked. See here:http://jerome.vernet.pagesperso-orange.fr/specs/Lisa/Lisa.html My 2/10 profile internal disk had the same problem, I found some page on the net about this problem an d fixed it by moving a little bit the head brake.
