My sister got a new MacBook Pro last week, so she's giving me her old 12" PowerBook G4, whose casing is severely warped. So, I helped her erase all her data, and I heard about the Zero-Out capability of Disk Utility. Unfortunately, I didn't realise that you had to execute the operation on another disk. It filled up her entire hard disk and then erased what it filled. After reading a common sense handbook, I had her get out her Mac OS X Install Disks, and I then went into Disk Utility, but did the erase option. After about 30 minutes, it was all gone, and I mean EVERYTHING. Only about 25 MB of the disk was used. Mac OS X was not installed; there wasn't even a volume on the disk, so I had to install Mac OS X. I let her supervise it while I did some work down the hall. Then, later, she came back and told me that the computer died and that there's no power in the battery. Her charger is warped and cannot be used, so it's nobody's fault. I was hoping it could install before the battery died, but it clearly didn't. I can't get another charger until my brother comes home next week with his PowerBook. So, I have no idea what it's going to do when I try and boot from the DVD next week. So, is this bad?
