Hi Barney. Thanks for reply. I'm not worried about my data. Stock sales, tax returns,papers,spreadsheets,journal articles, in other words, anything involving numbers or words as pertain to my personal or professional life are backed up every day at 3 a.m. by MOZY. Once a week I move such things to drop box and I have 2 16GB memory sticks.
When I installed Lion, my data was protected but apps no longer worked, battery time went from 7 hours to 3 hours, I couldn't find some apps and some folders. Pictures,tv shows,videos and movies I purchased at I Tunes and elsewhere that I really didn't care about but would have been nice to have kept were gone.
By the time 10.7.4 came out,almost all non-I Tunes issues (except the battery) were resolved. Virtually everyone at these boards insisted i should have done a complete backup and clean install which I still want to do but this seemingly simple task is becoming a royal pain in the butt. Until Lion, I had downloaded every new OS just like Apple says to with no problems. I don't want to go through what I went through with Lion and will get another external hard drive and buy Carbon Copy Cloner if that's what I should. Already purchased Disc Warrior per CCC suggestion and will bite the bullett if you say to
