HFS+ volume mounts on 8.6 but not 8.1

[ArmorAlley]

I had AppleShare Server 6.1 running on an mac OS 8.6 volume. The OS started behaving in a strange way, so I booted into another drive, wiped the AppleShare drive, and re-installed both OS and AppleShare.

This time I re-installed Mac OS 8.1 instead of Mac OS 8.6. All went well until I noticed that the drive I wanted to share wouldn't mount. It had mounted under Mac OS 8.6 with no problems.

I now get a dialogue box during startup asking me if I'd like to format it.

I also have a Mac OS 9.2 volume on this Mac (Beige G3) and the drive in question mounts without any problems.

Before I start with Norton Utilities on the drive in question, is this a known phenomenon?

Does anyone have a workaround or a fix?

That's weird!

It should "just work" with 8.1. Are you sure that's what you have installed, and not 8.0?

8.0 doesn't support HFS+; 8.1 is the first version that does.

If you do have 8.1 for sure, did you format the drive using any unusual utilities? It could be a non-Apple driver that's not playing nice with 8.1, or maybe a slightly out of spec filesystem structure that the newer Mac OSes are more tolerant of for some reason?

I suspect that it is a disk driver incompatibility. I format all drives either with Silverlining, FWB Hard Disk Toolkit or via the Mac OS. This drive is my primary archive and I formatted it many years ago. It's probably a good time to clone the drive and go investigating.

I reckon you’re on the money there - the driver (and related settings), not the partition is out of spec.

I’ve been getting a HFS+ drive up and running on my 840AV and found Silverlining to be by far the best utility for compatibility, if Apple’s version has issues with the drive or SCSI controller. After trying several versions of FWB Toolkit, I wouldn’t bother with it anymore.
