logic problems, disk too slow Options

[gemmar]

Hi,

have a problem concerning disk speed using logic audio 4.7 Platinum. With audio track number 10-15, depending on particular Track, my powerbook (titanium 400) comes up with disk too slow error. Can someone explain this to me, i thought, running 12 little audio tracks of 2 to 8 bars length shouldn't result in any problems (o.k., there are some compressors, reverbs and delays running in parallel, but this shouldn't matter to the harddrive, or what?), anyhow, why is such a small amount of data not kept in the RAM anyway? I just have 256 MB, would it help to put in more to improve the situation, or do i have to play around with some parameters inside Logic, which?

any help appreciated

thanks again,

will do what i can afford, the maxtor is firewire, so i hope it will work (i'm going to test it tomorrow, if this really improves the situation, i will tell here).

Before i'm going to defrag my harddrive (norton says it's basically ok, but what means basically?), i have to backup my system first, cause i have concerns, it might not work afterwards. This i never did on a mac before (this is my first mac and i bought it just 3 months, so i'm not very familiar with the system).
