I have a 30Mbyte Magic 30 SCSI hard disk made by Rabbit Technologies and experience the following problem. With the HD running, regardless of whether it was the startup disk, regardless of whether the application launched is on the HD, programs which operate in realtime run much slower and jerkily. Example: in Lode Runner, the little man takes one step then pauses-- totally destroying the game, needless to say. If the hard disk is turned off, and the program run from floppy, it works fine. Example: in Full Paint 1.0 when defining a rectangular region, the marquee runs normally while the mouse button is still down (must be in Quickdraw exclusively), but jerks after the button is let let up. We called Rabbit Technologies who claimed that the problem was with the Apple ROM (!!!)... that every SCSI hard disk has the same problem when there are many files on the disk. Does anyone know what is causing the problem and what can be done to fix it? Thanks in advance.
