Dear All,
Repaired hard drive and permissions. That did not help. I have OS 10.8.2. I have not yet upgraded to 11.0.2 because I am having these recent problems. The problems aren't a result of moving to 10.8.2. Everything worked fine initially after that upgrade.
I have two apple internal hard drives. One is a 320GB drive. The other is a 1TB drive. They were purchased from apple, and I believe both are Hitachi (I know the 1TB is for sure). All my external hard drives are Seagate GOFlex, one is 1TB, the others are 2 TB. I have 10 GB RAM, the original 2 GB + 8 additional GB installed. The DVD drive is the original with the MacPro.
The original internal hard drive has never been reformatted, just repaired with Disk Utility. The second internal hard drive is only a year old. Any other questions I missed?
I guess my next try is to reinstall OS X. Is that the consensus of the group?
By the way, I don't know if this helps, but when I open Finder, it doesn't "see" my main internal hard drive on the left hand side. I do see the 2nd internal hard drive and external hard drive, but it takes a while (over a minute) to see them. The main hard drive, however, shows as mounted on the desktop. Net, I can get to Disk Utility via clicking on the hard drive on the desk top but not via Finder. Don't know if this helps or not, but thought I'd throw it out there as it seems bizarre to me.
