I have seen no confirmed reports of other utility programs causing damage or data loss on machines due to this problem however, I also haven't seen confirmed reports of other utility programs fixing the problem or consistently identifying it. However, I've seen reports that Symantec's MacTools and even Apple's Disk First Aid have identified "uncorrectable" directory damage on disks with this problem.

Other Utility Software - This problem seems to bite NDD harder than other disk recovery software.

They can talk you through a series of steps that should result in your recovering your data if you haven't added files or written data to the disk since the problem hit you. If you've already run NDD, experienced this problem, and want your data back, don't add files or try to correct the problem instead, call Symantec technical support at 503/465-8440. The disk must be reformatted using the disk formatting software Apple supplies with the machine (Apple Drive Setup or Apple HD SC Setup), or a third-party utility such as Drive7, Silverlining, or Hard Disk Toolkit.

Similarly, merely updating the driver on the disk will not correct the problem. Booting from another disk and choosing Erase Disk from the Special menu or deleting all the files is not sufficient. The second, more thorough option is to back up all your data, then perform a low-level format of your disk. The Disk Spot Check utility only needs to be run once from that point onward, it's safe to use Norton Disk Doctor on the disk to attempt to repair any existing or future problems. It will be available on the Info-Mac Archives soon. In the meantime, Ric Ford has kindly reposted Symantec's utility and information on the problem at his MacInTouch Web site (thanks, Ric!), and the program is also available in Symantec's AOL and CompuServe forums. It should be available via Symantec's FTP site but that site has been having intermittent problems.

Symantec has just released a free utility called Disk Spot Check that can both detect the problem and eliminate the residual "ghost" data if the user so chooses. If you have a machine with this problem, it's unlikely to rise up and bite you in the next ten minutes. Additionally, the problem has been reported in 6100-series Performas, Power Mac 8500s, and even a Quadra 630 (although I find this last hard to believe due to the drastic differences in the drive architecture of the machines). As of this writing, sources inside Symantec and Apple have reliably confirmed that the problem has been detected in the Power Macintosh 5200-series, 6100s, 6200s, 7100s, 7200s, and 7500s, all purchased since 01-Jul-95. So far as I can determine, the article is at best only partly accurate.

This article gave a range of machines and serial numbers impacted. Computer Society, a long-standing Apple user group in British Columbia. So far as I can determine, a description of the problem first appeared in E-News, a newsletter from Apples B.C. Who's Affected - The bottom line: people who have purchased any Power Macintosh computer since 01-Jul-95 should be concerned.
In reality, the data on the drive is intact and untouched however, the directory information that enables the Macintosh to locate and retrieve that data is damaged. However, NDD's attempts to fix the problem often result in the disk being unusable and (apparently) wiped of its data.
The problem only appears on internal hard disks, and does not appear on or spread to additional storage devices connected to these machines. Some claim the disks were delivered to Apple with this problem others indicate there may have been a subtle error with Apple's preparation of these drives in manufacturing still other sources point to a combination of these factors.
The precise origin of the spurious data is unclear, and "informed" sources have pointed to a number of possible causes. The root cause is extraneous "ghost" directory information on some hard disks that Apple has been shipping in newer Macintosh models. The problem, although potentially serious, is easy to detect and, if you've already been hit, you may be able to recover your data.ĭefining the Problem - There are actually two problems: the first resides on the hard disks themselves, and the second lies with the way NDD reacts to those hard disks. If a user tells NDD to fix these problems, the program may crash toward the end of the repair, rendering the disk unable to boot and apparently losing all data. Symptoms include NDD reporting errors with disk directory information and allocation block sizes. Last week, problem reports began circulating about troubles with Norton Disk Doctor (NDD) and newer Macintosh models, particularly new Power Macs.
