Volume bit map errors |

I constantly reboot among 10.2.4, 9.2.2,9.1. The're all on the same hard drive, but separate volumes. 'Norton Disk Utilities' is constantly finding VBM errors on the 9.x volumes. I run 'Disk Doctor', do the repairs, and as long as I don't move to another disk, all appears fine. Anyone else experiencing this issue? Do you live with it or is there a fix? My Mac is a family machine and everyone has different preferences for operating systems. 8500/XLR8-G4-450/786RAM - Mitch |

Don't believe Norton, do run DW (2.1.1 or 3.0). For me, the DW3 CD is useless as it lacks the latest drivers needed by the UL3S and maybe other ATTO cards running Jaguar. ATTO posted drivers and OS X firmware in Dec 2002, but even with 10.2.6, Apple is at the old Jul 2002 level, pre-Jaguar. I'm also using SoftRAID on all my SCSI drives, cloned OS X over w/o installing, much more reliable. Norton will cause major errors to get worse if it finds any. DW 2.1 will repair the boot blocks before you do anything, and the volume root creation date, meaning run DW before you install any files on a volume. And use Norton for minor bit map things. And never be without a bootable backup copy of your system and files, including Jag. |

I agree Disk Warrior is the way to go. If it doesn't find volume bit map errors they likely aren't a problem. As noted in another topic Disk Warrior 3 isn't currently of much use to us if you already have version 2.1 . It doesn't run in OS 9.x and can only be ran on Old World machines like ours if you have two OSX systems on your machine. It can not do repairs on the booted system disk/partition. DW 3 does include a copy of DW 2.1 so you can boot the cd from OS9 and run DW 2.1 just like the DW 2.1 CD. Ryan is planning on adding CD booting with XPFacto 3 but it's anyones guess when that will happen. Norton file saver is likely the problem.I took it off my machine several years ago lots of reports of problems with it from many people. |

Well I had this problem when I was using my system for 9 and X booting. Well The actual problem is that Norton ONLY reports this error. Here are my findings. I run NDD in order to fix all the problems. After that The disk is OK. So I boot in OSX. I boot in single user moder and I fsck my disk. The disk is OK. After some work I rereboot that machine and I redo an fsck. The volume is OK. Then I reboot in OS 9 and the NDD tells me that there is a problem. I say OK just dont fix it. and run Disk first aid. and the disk is OK. I run Tech tool and the disk is OK. Strange egh. |

After reading your comments it dawned on me that it's always Norton 'File saver' that is reporting the problem. When I contacted Symantec, they showed a keen interest in this problem but no real suggestion other than what I had previously done. I have Disk Warrior, but it never 'found' the errors. Thanks for the input, you've really helped. - Mitch |

Oh, I didn't really answer your question. Norton utilities is notorious for reporting this error among others. I suspect that whenever you switch partitions to boot another operating system some data is written to the volume bitmap that Norton does not like. There have been long discussion on this at macfixit.com. The general consensus is that there is nothing to worry about. For example, if you repair your disk with another utility and then run Norton it will almost always report VBM error or some other kind of problem. It is really not as good of a utility as it once was since Symantec bought out the original company started by Peter Norton. |

Here's a second vote for disk warrior. I have Norton as a backup utility but never trust it to do a complete repair or report the actual condition of the drive it is run against. |

Get Disk Warrior and run that first and don't trust Norton. You might want to order 3.0 if you don't have it. |
