I was in the process of doing a complete reinstall on the this machine because of a broken registry. I got the original grey PowerBook G4 Software Install and Restore CD to run and the Mac OS X Tiger to install. When I started to try and reinstall my other programs from scratch on the specific CDs for them, my CD/DVD will run like it is going to boot them a few times, never boots them on the desktop, and then spits them out without me able to use them. I am not positive that the DVD/CD drive didn't stop working after the updates were installed. When I ran Dick Utility on the computer, and tried to verify the disk,this is what it said: Verifying volume HD Checking HFS Plus volume. Checking Extents Overflow file. Checking Catalog file. Checking multi-linked files. Checking Catalog hierarchy. %) Checking Extended Attributes file. Checking volume bitmap. Checking volume information. Volume Header needs minor repair The volume HD needs to be repaired. Error: The underlying task reported failure on exit 1 HFS volume checked Volume needs repair I was recommended to use Disk Warrior to repair this problem. Does anyone else have any suggestions to the best way to get my CD/DVD drive working again?
