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

Your track count might not seem like much but... to just a OEM internal hard drive who is running the whole system as well as recording... it may be too much especially if you are in 24bit audio. Try setting your disk cache down 256k in the memory control panel and then check to see if Logic has any preference for hardware buffer which may need an increase in memory. If you do this... it may help you get more tracks running but again... you can't expect too much from a single internal 5400rpm drive. I suggest getting an external firewire drive with at least 7200rpm if you expect to do lots of multi-track recording and mixing with more than 10 tracks. Also... majority of music apps do not load all the audio into RAM because there simply is not enough RAM to do that and run the system and app even if you do have 256mb which is not really a whole lot these days.

The last note... you might also want to use Norton Disk Doctor on your drive then optimize the drive (defrag) which may help also. A heavily fragmented disk drive will cause you problems too.
