I removed Norton from my computers within the facility I work in and my personal machines for the exact same reason. Norton came up with all these errors that Disk First Aid didn't find. Try this: Boot in single users mode (hold down command key and the S) type fsck -y and see if it comes up with any problems. If, it says changes were made continue to run fsck -y until it comes up with no changes were made. Then type reboot. This command is the Unix version of Disk First Aid. You mentioned Drive 10, that is an excellent application and may solve your problem as well. I would first run the command I stated above , then see what happens. Also, you may want to look into Unix tools to help with disk issues. Try Developer Depot www.devdepot.com type Unix Utilities for OS X it should come up with some software that may help not only with disk issues but command line, printer,etc. -----Original Message----- From: Goldberg, Franck (x2187) [mailto:FGOLDBERG at PBWT.COM] Sent: Tuesday, June 10, 2003 9:23 AM To: Power Macintosh G4 List Subject: [G4] Catalog B-tree damaged ? After a recent MS Explorer crash, I ran Symantec (Norton) Disk Doctor. Without success, as it stopped with error 23019. Apple Disk Utility said my disk "appeared to be fine". Symantec Online Technical Support informs me that 23019 means that the Catalog B-tree is damaged, and the solution is to back up and reformat. Are there any ways to fix this without backing up and reformatting? Would Micromat Drive10 fix it? SubRosa Soft DiskGuardian? (DiskWarrior X is not currently available). Any suggestions appreciated.
