I have a PPC PowerBook 17" from 2005 running Leopard that has worked like a CHAMP for all these years. I have to upgrade, because I'm tired of all the incompatibilities, but hope to keep it going until the end of the year for financial reasons. Problem is, it has a disk problem and Repair Disk fails.
I ran Apple diagnostics from my original system install disk. It failed: Mass Storage - error detected Error code 2STF/8/3:ATA-100 ata-6 - Master
Tried to boot into Safe Mode but it just dies after a while.
Booted into Single User Mode to run /sbin/fsck -fy and results are:
...Checking catalog file
disk)s3: I/O error
invalid key length
** volume check failed
/dev/rdisk0s3 (hfs) EXITED WITH SIGNAL 8
ran the command again with identical results. I was hoping to see some change in the error code.
The computer does boot and run "normally". I have a full Time Machine backup but can't figure out how to restore. Have other backups as well, but want to fix this disk problem before I go erasing and reformatting anything. It's at least working now. I seem to remember that fsck takes additional parameters, including telling it to use an alternate superblock (is 32 still an alternate superblock - used to be in BSD) - would this help? Can anyone advise me on the correct parameters for repairing the drive from Single User Mode?
What version of Unix is the OS based on? Is it BSD?
Found the disk. Last night I used it to Repair the backup drives, as the boot drive was still unfixable. I have a couple of options - there's a Firewire disk with some year-old Time Machine backups, and a newer USB drive which has current TM backups on one of its partitions, plus an image backup from last year.
I might as well format and reinstall on the internal drive, as that preserves all the backups, and see if the hard drive is truly failing. That laptop has just been a stellar piece of hardware - it's been my daily workhorse since January 2005! I've never had any other computer give me eight years of reliable service.
I confess I'm puzzled about Time Machine. It has a restore button, and when I selected a date from a month ago (thinking that recent backups might hold a corrupted file due to the hard drive problem) it prompted me to select a destination. I didn't see any option for a full restore. Is that because TM is smart enough to know that only one file had changed?
It might be better to not put all the junk back on - to do the fresh install, then just reinstall the programs I use regularly. I'd like to get all my mail back. Can I use Time Machine to selectively restore specific programs, or say, just the user data files? Isn't there a decent online reference for Time Machine where I can read up instead of asking for help?
It seems like Apples's got to be refreshing or coming out with new versions of the Mini, which is the replacement machine I want, so I hate to spend a lot on the old machine.
Thanks for all your advice - I appreciate the help.
