Disk too slow - repost

In June of last year I posted the same question but my thread was archived.

I now have upgraded my Mac Book Pro to 8Gb of RAM and I have a SSD hard drive. I still get the "disk too slow" from Logic Pro 9 every once in a while.

I use it in 64 bit mode, with 44.1Khz sampling rate for recordings and the cache is 256. After I did a repair on disk permissions using the disk utility, the disk too slow message went away for a while but it came back.

I record 16 tracks of real instruments at a time via a Mackie 1640i on firewire 400 cable. Maybe some Pros here can chime in on the buffer configuration settings, I have a feeling this is the problem. I should not be getting a "disk too slow" with an Intel SSD hard drive.

3.06Ghz MacBook Pro 17", 8Gb RAM, 160GB SSD HD, Glossy, OSX 10.6.6

Two things to try..

Since you're not monitoring through Logic you can increase the I/O Buffer (cache) to 1024.

Make sure Software Monitoring is off.

Also, experiment with Process Buffer size.

The disk to slow message is a bit ambiguous what Logic means is that it's losing data, several factors can add up not losing a few bytes of data, it's not just disk access.. are you running any secondary applications in the background.

pancenter-

p.s. create an external MIDI track and select it before recording, deactivate the track record button.
