This is something I discovered while working with the Mac of a friend. My friend had just optimised his harddisk with speeddisk from Norton utiltities. As an experiment, we tried to run Diskexpress 1.06, to see if according to diskexpress, the disk was also completely uptimised. But diskexpress gave the following error message: 'The directory of this volume appears to be damaged. More than one file owns the same block' Norton SpeedDisk seemed to have ruined the harddisk. We ran HFS recover, which also claimed that there were problems with the disk. The Norton diskcheck program insisted that there was nothing wrong with the disk. We tried the same with my Mac, but on a soft partition. Same results Can anybody else duplicate this Error ?

I can't duplicate the bug cited above (speed disk resulting in two files using same physical part of disk), but I have seen the following happen, three times on two different macs: QM Administrator (quickmail, CESoftware) crashed. I run Disk First Aid (Apple's program to check fsys structures on disk, which i try to run after every crash...surprising how often programs crash with files open and...trash some directory structure or something), it reports something needs fixing (that's all it ever says, never explains what), i say fix it. I run Norton's Disk Doctor, it finds a couple serious things wrong (volume bit map, and something blocks...i wrote it down, but not with me now...), i say fix it. I re-run disk first aid, it reports problem (again!), i say fix it... u get the idea? Each program "fixes" something, which causes the other program to see something wrong and "fix" it...they fight each other! So, who's right? I called Norton and they seemed unknowledgeable and uninterested in help ing. Since Apple wrote the file system, i would tend to trust their file system checker (disk first aid) in such a dispute...but bottom line: i backed up entire disk (daisy chained another hard disk), reformatted, and restored, to be safe. Then, of course, both disk first aid and norton agree that disk is good. Anyone else seen this? Any ideas what it might be? -- ---- Drew Wade drew@objy.com
