Classic startup problems Classic
[Editor's note: See the comments for a discussion and potential solutions to this problem]

I just redid my hard drive configuration on my PowerBook g4. I now have 3 partitions. 1 for OSx - formatted usi ng the UNIX file system, 1 for os 9.1 formatted in HFS+ and a big partition i use for storage which is formatted also using HFS+. I'm in osX and every time i try to start up classic i get a very interesting error message saying:

"This startup disk will not work on this Macintosh model. Use the latest Installer to update this disk for this model." ... and it gives me only one option to click on: restart

What does this mean and how can I fix it.....

The first time you run Classic, you need to start it from an HFS+ partition.

The solution is in the Tech Info Library in the form of an article for the public beta. See: . however, I couldn't find "Classic" in "Applications" in the release version.

Instead, copy Classic Startup from /System/Library/CoreServices to your HFS+ drive/partition, then double click that copy in the finder. This should start you up in classic for the first time. (From then on it will start from there automatically).

Hope this helps.

SamR's probably right...

I read this TIL on the Apple page, and it definitely seems to match what you're describing. Follow his instructions, and you should be good to go.

A general comment - everything I've read has said that HFS+ is the way to go for an OS X install, unless you absolutely need the UNIX file system formatting. There have been reports of speed hits from UFS, and there's this Classic compatability issue that you've run into. If you can do it, it may be worth your trouble to make your OS X volume HFS and not UFS.

You need your original install CD
Authored by: Anonymous on Mar 28, '01 05:03:25AM

If I understand your situation correctly, I think the problem is that your powerbook
requires a newer version of System 9.1 than the "official release" that works for most
other Macs. The CD for MacOS 9.1 that came with MacOS 10 is that "official release" CD.
If you need to reinstall, you need to do it from the CD which came with your Mac, and
not the 9.1 CD that came with MacOS 10...

[note that I do not have a G4 powerbook, so I'm just guessing here...]

Absolutely correct. You can't start the Macworld Macs from that disk because they come with newer disks. Use the disks that came with your machine.

Same problem error starting classic
Authored by: Anonymous on Mar 31, '01 02:53:51AM

I am having the same issue, and either I did not understand the fix, or it did not help. I have installed 9.1 from an original commercial CD, and also re-installed OS X. I also get a Carbon Lib error when I attempt to start up IE from the dock. Any help at all would be greatly appreciated.

I ran into this. Reason you're seeing it is because you installed using ufs rather than HFS+.

Reinstall using HFS+, and then Classic will work. The install will also run about 3 times faster, too.

I had this problem too. The first attempt to fix it was a reinstall. The problem persisted. The second attempt was to delete the System Folder for 9.1 (and the old folder for 9.1 too) and then reinstall.

The third fix did the trick. Go into OSX's control panel, select Startup Disk, and then pick OS 9. This seems to bless the folder somehow. Now, Classic will start.

The System Prefs StartUp Disk 'Blessing' Fix worked for me as well.
