I had major issues with a hard drive I initialized using OS 9.0.4 Drive Setup when I reverted back to 8.6. Mac OS Extended disks actually have a system file on the invisible Mac OS Standard partition and OS 9.0.4 handled this differently. I'm not too sure if its backwards compatible. I eventually backed everything up, re-initialized under the Drive Setup that came with 8.6, and have been a happy camper since. The first thing I'd try is Disk First Aid 8.6 - not to be confused with the OS version. This was an update that came out in between OS 9.0.4 and 9.1 that fixes some issues with that invisible system file on the Standard partition. Also, I'd try trusty Disk Warrior, maybe a Drive Setup "Update Driver", resetting the PRAM, and last but not least, the backup, re-initialize and restore. Good Luck, Jay P.S. Disk First Aid 8.6: http://asu.info.apple.com/swupdates.nsf/artnum/n11889 That's North American English. Do a search for the International English version if that's what you need. on 2/2/01 10:53 PM, Ron at [EMAIL PROTECTED] wrote: > I fear I've gone and done it this time.
