What is Blank hard drive disk images HFS/HFS+ (from 100MB up to 120GB)?

All these download files consist of extremely compressed empty disk images for emulators (such as SheepShaver or Basilisk II) that are to be used as hard drive to store files and/or the operating system.  Once inflated, they will instantly take the whole space they are marked at.  These empty disk images range from 2GB HFS formatted (appropriate for Mac OS 6, 7 or 8) up to 32GB HFS+ formatted (Mac OS 8.1, 9 or early Mac OS X).

Note: Please be patient when extracting these blank disk images, as your hard disk has to write the whole space (up to 30GB) so it might take a couple minutes depending on your computer specs.

Want to make your own blanks?

Under Windows, one can make a blank of any size using this program: http://www.emulators.com/freefile/makedsk.zip

Under macOS and Linux, one can make a 50MB (102400/2/1024) blank w/ this command line: dd if=/dev/zero of=my_image.dsk count=102400

Under Windows Vista or newer, one can make a 50MB (50*1024*1024) blank w/ this command line: fsutil file createnew my_image.dsk 52428800

...Note from that-ben: Once the blank is made, it's just a big zero-filled file. You have to create one or more partitions in it before you can mount/use it.  I usually attach the blank file to QEMU and boot Mac OS 9.2.2, then launch the DRIVE SETUP utility app to partition as HFS and HFS+.  Then it's usable under SheepShaver or any other Mac emulator, basically.

 

HFS vs HFS+ quick tip from that-ben: Even though HFS standard is highly compatible with almost all Mac OS versions, it still remains the worst choice for anything above Mac OS 8.1 in terms of efficiency.  The reason is the bigger the hard drive in standard HFS (not HFS+) is, the larger small files will use.  For instance, think of a 30GB drive that you format as HFS standard (though this would only be possible on System 7.5.2 or newer).  Just a couple characters typed in a SimpleText document and saved on that drive will always result in a minimum size of nearly 1MB (1000000 bytes) instead of say, 8 bytes! This is due to the 16-bit blocks addressing limitation. The way HFS standard was implemented, there can only be limited small amount of blocks on a single drive, resulting in those blocks to distribute the hard drive space evenly and thus, be huge.  Even if you write tiny files, the remaining bytes in those blocks are totally wasted, resulting in humongous files that contain next to no DATA. In other words, if you're planning on using, say more than a 10GB big drive in Mac OS 9, you should totally go with HFS+ as it will contain WAY MORE files than a same size HFS standard drive.

Note: For System 7.5.1 and older, the maximum usable size of a volume is 2 gigabytes.  For System 7.5.2 and newer, the maximum usable size of a volume is 2 terabytes, but this is discouraged as it then renders those drives incompatible with previous versions of Mac OS.
