Emulation
This app works with: SheepShaver, Basilisk II,

These are empty (blank) Mac formatted disk images, ready to be used with Mac emulators, SheepShaver & Basilisk II (maybe Mini vMac with the HFS drives)

1st DL: is a HFS Standard IMG for emulators, expanding to a little more than 30GB.
The file is compressed with bz2, so its only 41kbyte.
You may inflate it in OSX with The Unarchiver or by running bunzip2 from the command line.
Copy this into Terminal, presuming your bz2 is located in /Classic:
bunzip2 -c /Classic/HD30.img.bz2 > /Classic/HD30.img
In any case patience is needed and enough space to store the inflated image.
To expand on Windows simply use WinRAR or any other ZIP extracting tool.

2nd DL: above is for a 30GB HFS+ disk image for Mac emulators running a Mac OS 8.1 to 9.0.4
Compressed as bzip2, to expand on Windows simply use WinRAR or any other ZIP extracting tool or use commandline: bzip2 -d big-32g.img_.bz2
If using this with Basilisk II running Mac OS 8.1, HFS+ disk drives can only be used as a secondary disk drive.

3rd DL: a 10GB HFS+ disk image for Mac emulators running a Mac OS 8.1 to 9.0.4

4th DL: a 10 GB HFS disk image for Mac emulators running a Mac OS 7.0 to 9.0.4 (tho' for emu's running 8.1 or later, its better to use HFS+ and not HFS).

5th DL: is the 6GB image from Emaculation, it's HFS+ Journaled, mainly meant for PearPC, but also usable with other emulators after initializing.

6th DL: a 3 GB HFS disk image for Mac emulators running a Mac OS 7.0 to 9.0.4 (again, for emu's running 8.1 or later, its better to use HFS+ and not HFS).

7th DL: 120GB disk image; HFS formatted. If anyone plans to use it note the comment below about HFS+.

See also:
  • A DOS formatted 1GB disk image (2nd DL on that page) - which is mainly intended for use with Mini vMac and file exchanges between Mini vMac and a Mac host running Mac OS X 10.6 (Snow Leopard) or later.

  • Some further discussions/ideas on Disk Image creation of emulator (large capacity) disk drives.

Compatibility

HFS vs HFS+:   Since the 1st DL (30GB) drive is formatted HFS (not HFS+), the problem you will run into is that very small files (e.g.: A few letters typed in a SimpleText document) will always have a minimum size of nearly 1MB (+1000000 bytes) because of the 16-bit block addresses limitation. Many fewer blocks could be allocated on standard HFS drives resulting in very large block sizes (less blocks cover more space). In other words, if you're planning on using this 30GB drive in Mac OS 9, you should consider using the other file (HFS+) instead, it will have the capacity for storing MANY MORE files, even if its of the same drive size as this one.

It's worth mentionning that with any actual OSX version, you can simply pop up the Terminal app and copy/paste this line which will automatically create, initialize and even format a blank HFS+ disk image 100% ready to use in SheepShaver (and adapt the "1G" to any other amount of GB's you need the disk image to be):
hdiutil create -fs HFS+ -o "diskimage.img" -size 1G -layout SPUD -type UDIF -nospotlight

Thanks 24bit and MikeTomTom for this very useful page. I confirm both disk images extract correctly using WinRAR on PC and mount perfectly in SheepShaver under MacOS 9.0.4. The HFS+ file extracted in less than 4 minutes.

I think this page should be pinned on the forums for newcomers/starters. We should also add a standard HFS 3.9GB image, which is the maximum SheepShaver can format. At 4GB, I don't think HFS+ would make a big difference and HFS+ is less compatible with older MacOS versions anyway.

On a side note: To my big surprise, HFS+ drives are fully formatable from SheepShaver under MacOS 9.0.4. It does not limit the size to 3.9GB like standard HFS disk images do! This is something I'm quite happy to see.

Thanks again MikeTomTom and 24bit for this excellent and useful work.
