Although very similar to the 400-kilobyte drive which newly replaced Apple's ill-fated Twiggy drive in the Lisa, there were subtle differences relating mainly to the eject mechanism. The drive case was designed to match the Macintosh and included the same 400-kilobyte drive (a Sony-made 3 + 1⁄ 2-inch single-sided mechanism) installed inside the Macintosh. Bill Fernandez was the project manager who oversaw the design and production of the drive. However, it did not actually ship until May 4, 1984, sixty days after Apple had promised it to dealers. The original Macintosh External Disk Drive (M0130) was introduced with the Macintosh on January 24, 1984. 3.3 Macintosh PowerBook 2400c Floppy Disk Drive.3.2 Macintosh HDI-20 External 1.4MB Floppy Disk Drive.

Apple produced only one external 3 + 1⁄ 2-inch drive exclusively for use with the Apple II series called the Apple UniDisk 3.5. The Macintosh external drives were the first to widely introduce Sony's new 3 + 1⁄ 2-inch rigid disk standard commercially and throughout their product line. Though Apple had been producing external floppy disk drives prior to 1984, they were exclusively developed for the Apple II, III and Lisa computers using the industry standard 5 + 1⁄ 4-inch flexible disk format.
Later, Apple would unify their external drives to work cross-platform between the Macintosh and Apple II product lines, dropping the name "Macintosh" from the drives. You could do the scan process later, but I prefer to do it immediately, so the image'll be ready to go if I ever need it.The Macintosh External Disk Drive is the original model in a series of external 3 + 1⁄ 2-inch floppy disk drives manufactured and sold by Apple Computer exclusively for the Macintosh series of computers introduced in January 1984. Why "Scan Image for Restore"? So you can use Disk Utility's Restore feature to restore it to a disk later (or use the command-line asr tool to do the same thing). Including the empty space can cause trouble if you ever need to restore it to a smaller volume. It also makes the image just big enough for the files, since it doesn't include all the empty space in the original volume. if the original was bootable, you can restore the image and the result will be bootable). Why image "from Folder" rather than from the device? Because it creates a cleaner image (files all defragmented, etc) but preserves everything that matters (i.e. Once it's finished, choose Images > Scan Image for Restore, and have that process the newly-created image. In the save dialog, make sure Image Format is set to Compressed, and it's best to save it somewhere local (and copy it to the NAS afterward). In my experience, the best way to image an HFS+ volume is to mount it (note: don't try to image the volume you're running from at the time), open Disk Utility, choose File menu > New Image > Image from Folder, and select the top level of the volume as the "folder" to image.

There's also a fixed-size read-write format, and a read-only (uncompressed) format, which'll store the same thing, but take up more space for no good reason.Īll the versions you mention will be in HFS+ (aka Mac OS Extended) format. which is pretty irrelevant for archived systems. The sparse formats are useful for when you want the image to be able to expand later, when you add to them. For archival images, I'd use the "compressed" format (which I think you'd consider "fixed", but it's one of a number of fixed-size formats).
