A disk allocation setting or buggy? Please help!
 

Hello all. In short..

-Old PT LE 7.4 /white macbook 10.5/ usb external HD/Mbox2pro firewire.
-always running smooth / no issues

In my previous sessions, PT would ONLY record onto the EXTERNAL hard drive and never the internal mac hd as I prefer.

Suddenly, It is now recording to both mac drive and external drive leaving audio files in both. When opening the PT session, it looks to relink.

I'm assuming I've set something or switched a pref accidentally but cannot seem to find this preference.

How do I designate only the external to record?

I know this is 101 but any help would be appreciated.
