Final Cut loading and running extremely slow...

Question

Hi, I posted about this a few days ago but in my usual panic (work to do!) I didn't make it clear, basically, here's the problem...
I recently had problems with FCP and generally all apps on my machine, when they loaded there was a slight pause when the icon bounced on the dock and I came across all sorts of errors, especially in FCP.
So, I backed up the two internal hard disks, formatted them both, then Raided them as one and put all the information back from the backup.
Since then everything's been working fine, I installed a new fresh copy of Final Cut Studio and I've done a few jobs.
Since finishing my last job last week (which happened to be working with MP4 files, I'm not sure if this is relevant), every time I load FCP now the icon struggles to bounce and it runs extremely slow, even if it's loading a new, blank project. From my last post, someone suggested I delete the render files from the MP4 project, I did so but still no luck.
I've run Disk Utility, Disk Warrior, no hope.
All other apps are fine but when I run FCP it slows the whole machine down, takes forever to force quit and restart until it's back to normal.
Next step is to re-install Final Cut Studio but even if this works, I'd like to have an idea why this has happened??? I've never had problems like this with my mac before.
Thanks, hope this is clear and not too much!

It would have been much better to find the problem than to just move it around.
All you have done is create a RAID where none was needed. When you moved your clone back to the RAId, you only moved all of the original problems to a new drive.
You are probably looking at a complete scorched earth-style reformat and reinstallation of everything from scratch since you've done so much damage.
There were a couple of things to try before you made the RAID but they would have been found by asking some questions and searching in the Mac OS10 forums.
