Hello, I used to have a 2002 iMac that after facing several electric outages while it was on sleep mode it was unable to start up. I believe I could get up to the white screen with an apple and thats it. I used DiskWarrior which some how fixed the file system and that computer worked well again. I was running Tiger. Now on my Macbook running Mavericks, I am facing outages because of the battery drying out of power. Is it possible that my files are get damaged and I need some maintenance to keep my laptop working in tip top shape?
