Hi guys. I'm seeing this error ("Incorrect number of Access Control Lists") upon running Disk Utility on my backup drive. (Backing up an iMac G5.)
David wondered why anyone would have ACLs on their Tiger drive. In my case, it's because I'm using ACLs to control multi-user access to a shared iTunes folder, as explained here:
http://ad.hominem.org/log/2005/07/acl.php
AFAIK, I only have an ACL set up on one folder (/Users/Shared/iTunes).
I suspect that one ACL is not being copied properly, which means that if I boot from the backup the shared iTunes setup I have may not work properly. However, unfortunately I can't complete a full Disk Utility verification on the backup disk because it exits with the ACL error, meaning I don't know if any other underlying issues exist. (None are reported so far.)
I should be upgrading to a new iMac soon with Leopard, so I'll take my chances for now that the backup will work properly if the need arises.
Hope this extra information sheds some light on the issue.
Joe
