As to the System Profiler report: It seems the driver you have is probably OK. You could try updating on one partition and run from it for a while. Just don't clone to your backup until you determine if it is running without problems.
If you can't seem to come to any conclusions with all this testing then just wait until you actually have a problem with running the computer. Ignore what DW says.
Just wanna get sure that all the back ups i've done are good and not corrupted....
the re install of all the things was a real pain....
If and when you have a real problem then take note of what is running, what externals you have connected and what the crash reports say. Wish there was a better answer.
Have not done all the testing but untill now (have disable spolight for all the drives, maybe that was part of the problem whith DW ? ) it seems ok , hope it gonna last
Gonna put back one at a time ,the Motu , firewire card and ram and see what happens
