We ran Disk Utility from my external hard drive and got Invalid Sibling Link 4928Any help? Comments Reply 1 of 2 osxaddict Posts: 131member September 30, 2003 7:43PM I got Invalid Sibling Link on my powerbook awhile back and AppleCare said that the only way to fix it is either a clean install or with Disk Warrior 3.DW3 did repair it....but I still did a clean install.
