I have a Mac Pro 2,1 and have been having some problems with it for some time. At first I suspected file system damage, so I backed up important data, and did an erase and install, and just reinstalled Final Cut Studio, leaving the backup on an external. But I am still getting some of the same problems, one hard drive will take up to 30 minutes to mount, it can't be backed up (carbon copy cloner fails saying either bad filesystem or bad drive, and just copy and pasting fails). Sometimes, using the Find command in Finder will not return any results. I am on Tiger 10.4.11, all the latest patches. Everything passes the Tech Tool analysis. Any one have any ideas?
