This must be a bug. I've seen several posts that describe the same thing. Haven't found a workaround yet. However, I hear from Beta testers that Panther resolves this problem. It would be nice to have this bug fixed, Apple. Some of us won't have the option of upgrading to Panther! Here are my findings on the bug:
Error: While booted in OS X, a normal user account with capabilities set to "Open All System Preferences" without "Change Password" (or "Open All System Preferences" is not checked at all) checked will produce the following error when he/she logs in:
You have inserted a disk containing no volumes that Mac OS X can read. To continue with the disk inserted, click ignore
Clicking ignore is the only option. The drives will mount normally and perform normally after this. Happens every time the user logs in, but only seems to happen with a second drive.
Configuration: One OS X drive (with no OS 9 drivers), second drive (with OS 9 drivers). Booting to OS X (10.2.6 with all updates). This is on a Dual 450 G4 with 1.25 RAM. Affects 10.2.4 and later. Tests performed so far with no luck:- Different drives (different manufactures: IBM, WD, Seagate--all IDE). No change
- Different jumper settings (Master/Slave/CS and vice versa). No change
- Disconnected the drive with OS 9 drivers- Error disappeared.
- Tried using older OS 9 drivers - ( from 9.0.4 and 9.1 disk utility) - no change
- Tried using pdisk,newfs_hfs, etc command line tools to format - no change
- Tried with and without OS 9 system folder on drive. no change.
- Reset NVRAM. no change
- Reinstalled new system with 10.2 system disk (boot disk - no OS 9 drivers). Tested for error with just 10.2 before updating to 10.2.6 and the error didn't exist. After updating to 10.2.6, the error returned.
- Created new user. Tried various capability settings.
Summary: The error only happens to users logging in, when, in user's capabilities, "Open All System Preferences" is checked without checking "Change Password."
[robg adds: I don't have any non-admin users, so I can't confrim this one -- can anyone else comment on a warning dialog at startup for non-admin users on multi-drive machines?]
