iMac G3 Hard Drive Issues

Hello, I know that this product is likely way out of support, but I still have questions. I have a summer 2001 iMac G3 (600MHz, 10.4.11) in a small collection, and when I use it, it runs pretty slow. It takes a lot of time to load certain applications, and initially I thought it was just because of its age. But then, out of curiosity, I opened up Disk Utility and got this message after Verifying the disk:

Verifying volume “Macintosh HD”

Checking HFS Plus volume.

Checking Extents Overflow file.

Checking Catalog file.

Invalid sibling link

The volume Macintosh HD needs to be repaired.

Error: The underlying task reported failure on exit

1 HFS volume checked

Volume needs repair

When I went to Repair the disk, it couldn't do that, probably because it had to unmount the only disk it has, which is understandable. And, after reading how to repair the disk in Disk Utility, I found that I need an OS X install disk. However, I lost the install disk for 10.4.11, but I have Mac OS 9.1, OS X 10.0, 10.1, and 10.3. I'm wondering: will it still be possible to repair the disk even though they won't be running 10.4, or do I have to have the same operating system as on the hard drive?

Second: If it is possible to repair the disk using an install disk that isn't 10.4, will I be able to install one of those operating systems (9.1, 10.0, or 10.3) and keep 10.4.11 in its place? Or will I have to delete 10.4 and install one of those systems?

Thanks for any feedback!

Favor from:

1) Disk repair is run when you start up in safe mode. To see if it worked, you will have to run disk utility again.

Try a safe boot.

Shutdown your machine. Hold down the shift key. Poweron. Wait awhile; wait awhile while you harddrive

is being checked.


You need to get into single use mode for steps one and two that are listed below.

This page will tell you how to get into single user mode.

Basically, you hold down the command + s key then powering on your machine. The command key has a little apple symbol on the lower left. It is between the alt/option key and the space bar. On a PC keyboard, it will be the windows key, I think.

1) ( Do you know Unix. You are in a Unix single user console. ) The setup commands you need should be listed on the screen. For Mac OS 10.4.11, the commands are:

# check out the filesystem.

# ( in case of partial success repeat this command until errors go away. )

/sbin/fsck -fy

# reboot your mac

shutdown -r now
