Hello,

I am a returning amiga user after 5 years in the wilderness of windows and linux so excuse any silly questions in the next couple of weeks. :)

Looking at the Jacek Piszczek dual boot install guide i see he has done a roughly 50/50 split on a 80GB hard drive.
I wanted peoples comments and thoughts on what sizes I should use for both systems. I realise its different for everyone depending on what people do with there system but some ideas would be good nonetheless.

I seem to remember reading in amiga future magazine that the partition size limit is beyond my 80GB hard drive at something like 128GB? so that is not a problem.

Opinions please

Martin

Well, I got a 160GB drive exclusive for MorphOS, just the way it should be ....

DHx : (boot.img HFS) is 64MB which seems to be a waste of 60MB
DH0 : (MorphOSHD: SFS) is 512MB and 54% full
DH1 : (Work: SFS) is 40GB and 4% are used for apps and my projects
DH2 : (Data: SFS) is 38GB less then 1% used for things I've download and might or might not need sometime later
DH3 : (Media: SFS) is 70GB and 42% filled by my CD-collection

So you could get away with less then 10GB for MorphOS if you don't plan to host a large media collection on the drives.

Well having it only for Morphos avoids wasting space on those padding partitions that are needed for Mac OS X as well :)

So you have installed Morphos to dh0: and installed the Apps and Data to other partitions. I can understand it with windows since it gets infected so OS on 1 partition is a good idea.
Any reason to do that?

thank for your time

Martin

If you want OSX for some reason, I'd say 10GB would be fine for it. It's ok for basic installation and some extra stuff for occasional use. Leave the rest for MorphOS as it's better to watch movies etc with it IMHO :)

For MorphOS it's good to make more than one partition. One for system... apps could be on system partition too or on their own... and separate bigger partition for other data. If you like to keep your data clean and you want to use caches on browsers etc (I don't), you could have separate temp partition for it, because SFS gets fragmented bit too easily.

Have a 250gig hd with 5 partitions boot, data(40gb), work(40gb), sys80gb, and mac(80gb) Wish I had made mac smaller..Rarely use Mac side :)

Ok 10 GB for MacOSx basic install is useful thanks.

So you are saying split morphos and apps for a cleaner look on opening the partition? Makes some sense from the POV of clutter but i could do with another reason.

The temp files and cache is a good idea thanks for that.
There is no pagefile or swap in Morphos as yet?

Hmm a data partition to be shared between both OSes would be usefull.
question is would i have to use a FAT32 partition or could a write to HFS+ in morphos?

thanks

Martin

And to save space on OSX, don't install Garage Band example tracks or other useless stuff, they took several gigabytes IIRC.

Quote:

Cleaner look, easier backup handling, basic idea of having OS completely separated from other stuff, if you want to use different boot partitions/medias or replace system partition completely in upgrades etc, minimizing fragmentation effects...

Quote:
Thank god, no ;) Many Macs have 1GB ram and that's more than enough.. I think with that amount of memory it is better to use more memory cache on browsers and no disk cache at all.

Quote:

There's only read support for HFS+ on MorphOS.

Is that a single 250GB hard drive?

Does anyone know what is the largest pata (ide) 2.5" that is available?

I expect laptop sized HDs will be getting harder to find with sata and solid state drives taking over.

Good idea uninstalling some of the specialist apps.
I have osx installed already so i will do a resize for now.
I havent found any music tracks are garage band progjects in a different format to music?

I suppose the backups idea is one reason to split into partitions.
Oh well i will do it as its a traditional amiga way to have sys and work partitions :)

No write supports means i would have to use fat32 or does noone both with this and just uses flash drives instead. FAT32 is flakey on windows boxes.

thanks for the suggestions

I was thinking of having alot of music on the mini but it only seems to have a headphone socket which is normally poor quality when compared to a line out.

Do you have an usb sound output or some other way to improve on the sound quality. (I find my cowan D2 headphone socket poor quality along with other portable mp3 players i have)

I have a 320GB drive in mine which was the largest capacity I could find.

@trotter

I got 80 GB disk on Mac mini.

I left 10 G for MorphOS, rest for MacOSX (Tiger). I find it fair since all my content is stored on Mac partition (e.g. documents, pictures, music) and the said partition is visible by MorphOS (in a read-only mode though).

I have to add that I had been using my mac for nearly four years before MorphOS landed on it, and nearly two years as my main and only home computer. So all the stuff was already there.

I do want to share data between the 2 oses like i do with linux and windows with a fat32 partition.

Do you share data between the 2 operating systems?

How do you do it within morphos generated data? (since HFS is read only)



Martin

> HFS is read only

HFS is r/w, while HFS+ is read only.

Quote:

Ah interesting can it be used for data sharing then?
Is there a 2gig limit to HFS?
Might be worth considering it as a share partition.

thank

Martin

> can it be used for data sharing then?

Yes, obviously.

> Is there a 2gig limit to HFS?

Yes, according to http://en.wikipedia.org/wiki/Hierarchical_File_System max file size is 2 GiB.
Number of files and filename length seem rather restricted as well.

Hence I use my MacOSX files (i.e. music) on MorphOS but the other way, no.

I use the internal hdd for MorphOS exclusively. For OS X i use a firewire attached external hdd. The firewire plug also serves as "boot menu". If attached OS X boots by default, if not attached MorphOS starts directly. The external drive also has usb jacks, so one partition also serves as back up medium for the MorphOS drive and another partition (using Fat32) serves as common r/w space for OS X and MorphOS. Pretty convenient that setup. But OS X gets used only very rarely, anyway (but Garageband and MS Office are nice to have).

Thanks for the information it does look like HFS is less robust than even FAT32.

wikipedia: "It is also a serious reliability concern, as damage to this file can destroy the entire file system. This contrasts with other filesystems that store file and directory records in separate structures (such as DOS's FAT file system"

Right so you are using a FAT32 partition for data exchange then.

I dont really want to have a external Hard drive attached if possible since it takes away one of the niceties of the mac mini ie all in one box.

How can I format a partition with fat32 on morphos?
HDConfig only has a FAT entry for Filesystem, when I choose to edit a partition!?

Quote:

I guess its not supported by MAC partition table. Using MBR at least alows 6 FAT versions: 3 FAT16 and 3 FAT32.

Why not create a HFS partition for sharing files. That should work.

Geit

Quote:

Yes i was thinking the same.
Fat or MSDOS filesystem as its called in Morphos doesnt appear in Mac tiger. I cannot even select it in diskutility.

Next i will try the ubuntu livecd suggested in the dual boot install guide.

I can't switch from MAC to MBR without loosing my other partitions on the same harddisk;(
Quote:

I tried, but writing from MacOS to the partition was ok, I could read it then from MorphOS, but when I copied something from MorphOS, MacOS told me the partition is corrupt, and it couldn't be repaired. I had to reformat it from MorphOS...

Its not so important for me, because I use MorphOS fulltime;)
