Backporting HFS+ to Mac OS 8.0 and earlier

Posted by: Phipli on 2023-02-03 10:30:11

Quick question for you on the subject of Zip-100 drives and disks. How do you find their reliability? Because I’ve been using some disks that I’ve had since 1998 in a SCSI drive I got off eBay, and I’m finding that those disks are randomly corrupting themselves or becoming unreadable. Do you think the media might be worn out?

Might be one for a new thread.

Sorry. Maybe @rjkucia could PM me the reply if they liked 🙂

I meant for System 7!

Oh, you said HFS, not HFS+, that's why I got confused 🙂

Ah, curses, sorry. Mind in other places.

Re: Zips. No idea on "outside" media. The collection ive had for decades and kept in controlled conditions all work just fine.

The Text Encoding Converter needs to be in the Extensions folder. Is this extension supported under system 7.1.2?

I tested the extension and its runs without any issue in 7.1.2

Has anyone been able to explain why 7.5.3 fails when patched?

I made a simpler patcher. Grab it here :

Hosting it externally so I can make updates if needed.

I've included the listed resources, but from 8.1, is that likely to cause issues?

Pulled it down sorry - uploaded the wrong thing and I'm not at home. It will be sorted shortly 🙂

Try that 🙂

I can't get it to work with 7.5.3. It bombs on startup with an "Error Type 10"

The github lists 7.5.3 as not working?

I thought you might have fixed that since your patch is named "HFSPlus 7.5.x" rather than "HFSPlus 7.5.5"

Sorry 🙂 I haven't magiced a solution. I was just writing something for loading resources.

I wish I knew about this HFS+ support in 7.5.5 back when I was working on my 'recovery' image https://68kmla.org/bb/index.php?threads/best-rom-disk-for-rominator-gglabs.33110/

Posted by: volvo242gt on 2023-02-06 15:46:42

Cool. Downloaded it. Will try it out on the 650 this coming weekend and see if it works. Am running 7.6.1, so it should.

Posted by: soviet on 2023-03-02 14:18:14

Hi got the program resource miner, loaded the included 7.6.1 patch then select the system suitcase but when apply got several conflicts like the one in the picture.
If I choose to "apply to all further conflicts" and "overwrite" the result is a nonworking system folder that stuck on the happy mac.
Not sure what could be the cause of this.

I'm following up on a report that this is unstable and should be considered experimental because it could result in data loss.
Can someone confirm the current state of these hacks, as it may be appropriate to add an [Experimental] or [Unstable] tag to the subject of the thread.

I'd be inclined to suggest the opposite approach: everything in Hacks&Dev should be considered unstable unless explicitly stated to be production-ready and even then should be treated with suspicion...
