[QUOTE="Ntenze, post: 1429428, member: 214198"] I had many updates yesterday - I installed updates - for some reason finder kept shutting off, Everytime I hit send to apple - it would reappear - I tried to reinstall from Time Machine, but it kept failing at .05 percent - I then tried to erase drive and install a fresh copy of lion - then did a migration - it transferred all the files, but then wouldn't let me open anything - I tried to erase hard drive again so I could install yet, another fresh copy of lion. Now it won't let me erase hard drive -- Disk Erase Failed Disk Erase failed with the error: Couldnt unmount disk. Can another give me suggestions. I don't want to lose my info on time machine, I hope I can retrieve all info when I figure out how to get laptop back to factory settings [/QUOTE]
