My mac has been acting very weird since i installed leopard and ilife 3 weeks ago. 1. Running slow (taking a long time to open programs) 2. Sometimes when i click on my external drive icon its empty. 3. Grey screeen comes on telling me to restart. 4. Starts making a loud fan noise when i leave it on for a over 24hrs. Then this morning i turned it on to copy a file to my jumpdrive and i click on the external (seagate 250) drive and again its no icons or anything inside. So i go to spotlight to see if i can type in the name of the file and no file is found. But i did notice that it said "indexing" So i waited for 3 minutes. Then i did what i always do when it starts bugging out. "restart" After the restart it ask me would i like to initiate the disk drive or something to that affect. Please dont tell me my external is fried. I have tons and tons of work on it.
