Firewire Streaming Error In Pt 7.4, DAE Error 9073 Options

[Bukman]

Just started getting strange -9073 error messages saying

DAE can't get audio from the disk fast enough. Your disk may be too slow or too fragmented. A firewire disk could be having trouble due to the extra firewire bandwidth or CPU load..

This is happening on PT sessions with only 8-10 tracks of stereo audio and no plug ins running.

My drive is a Lacie 500Gb and partitioned into 2x250GB partitions and is connected to my intel imac via firewire 800. This makes it seem strange that this could not stream fast enough.

Anyway initially I backed up my firewire drive audio partition, erased it plus reduced the length of the Firewire cable.
This then worked okay for a while until yesterday when the problem came back again. After restarting the mac it seemed to be okay but I wonder if this is going to happen again.

Anyone else get this error and any idea what could cause it?

Seems according to digi support site that the -9073 error is a catch all and applies to systems not even using firewire which seems strange.

Cheers
