Also, they are only specced to run up to 80 tracks. Most drives will manage 82, if you're lucky; and maybe half of them will manage 2ms steptimes. If you go beyond the specifications, you run the danger of garbaging the disk drive. (Which is YA reason why track 81/82 copy protection is a REAL BAD idea.) I'd say that 83 track/2ms step was really pushing your luck. Whether trashing a drive could then infect the rest of the machine would then depend, I suppose, mostly on what the drive does when it goes.
