GSOS 6 and using HFS partitions

I have had positive experiences executing IIgs programs from an HFS partition (Games, utilities, etc...) I suppose I could also save games and files to an HFS too? Is this a safe practice with GSOS 6.0.3?

Also, is there a good utility for defragging HFS with an apple II? Does ProDOS fragment?

Norris,

Is this a Hard Drive, or a CFFA Card?

Sorry, I have a Reactive Microdrive and a SCSI2SD.

Norris,

So It's a CFFA Card with an SD Adapter.

I would think that if you have a hookup to your Mac (or PC) that you should
be able to do what ever you wanted.

But don't quote me. lol

OSX dropped support for HFS in 10.6, but if you have an older OSX or MacOS machine, you can move the drive back and forth. There is also HFS support available for Linux, but I've never tried it.

I have only modern macs which have long since dropped both file system/driver/interfaceface support for scsi2sd..

You can just mount the SD card with a reader. I keep a 10.5 virtual machine around for moving files. The original Mac Minis can be had for a few bucks and also serve nicely for that purpose.

Re: GSOS 6 and using HFS partitions

Not sure how things got off track (sorry, must have been me), but I really only had 2 questions:

1-Is it a safe/ok practice to use HFS partitions on a IIgs (System 6.0.3) as working partitions in the same manner one might use ProDOS partitions?

2-Are there any IIgs utilities for defragmenting ProDOS and HFS partitions?

Re: GSOS 6 and using HFS partitions

Answering your questions:

1 - It is generally considered that using HFS partitions on a IIgs is somewhat risky due to the HFS driver in GS/OS being a little buggy. Now having said that, most of the critical bugs were fixed way back in the 90's (remember GUPP?) and these have now been incorporated into System 6.0.3 I believe. On my IIgs's I generally have 4 32Mb ProDOS partitions and 1 large HFS partition, and from memory I still tend to get more errors creeping in on the HFS partitions as opposed to the ProDOS partitions. The beauty of using a flash based memory as the hard drive is that you can easily back up the entire drive using Ciderpress in a matter of seconds - then if you notice you have errors, you can simply reimage the flash media from backup. One other thing to note regarding HFS partitions, is that many games/apps will not run if they are installed onto the HFS partition. It's pretty much a suck-it-and-see affair. You certainly cannot install the system software itself onto a HFS partition!

2 - There are couple of defrag utilities, but I've not used any of them and I'm not sure if they support HFS partitions. Some of the ones I know about are:
* Vitesse had Deliverance (or was it Salvation?)
* Quality Computers had Easy Drive

I personally would not risk trying to defrag using these (would you gain much??), but feel free to experiment and report back. Make sure you backup prior to doing so though. I haven't checked, but I assume that one or both of these would be on the "What is the Apple IIGS?" site.

Cheers,
Mike
