It was a sudden occurrence. It was working fine just a couple days ago. Now it is laggy, it takes about 10 minutes just to start up, and seems to be incapable of exporting. My macbook pro says I have 84.4 gigs of free space. What could be going on?

Preference Manager for Final Cut Studio - Trash Final Cut Studio, Final Cut Pro Preferences - Restore and backup (http://www.digitalrebellion.com/pref_man.htm)

Try this free program first, reinstall FCP second.

Cole,

What most people don't realize about lagging system performance is that it's a sure sign that routine and even critical maintenance needs to be done.

Normally molasses-slow running apps are indicative of an OS directory that's badly in need of repair/refreshing. Download a copy of DiskWarrior right away, make a bootable DVD (or use CarbonCopyCloner to make a bootable image of your HDD on a separate or external) and get your directory fixed up.

Once your directory is cleaned up download and run all the maintenance routines in Onyx (free app).

After you do those two things if you're still having problems - which I doubt you will - let us know.

Thanks Robert,

You were indeed correct. In fact it turns out my whole hard-drive was nearly fried, which was in turn corrupting my video files.

My computer is still under warranty, and so I backed everything up, and had them replace the hard-drive for me. And now everything is working splendidly.

Thanks for the input.
