The G3 AIO was available in two basic configurations, a 233 MHz version with a floppy drive and a 4 GB hard drive, and a 266 MHz version with a built-in Zip drive, floppy drive, and either a "Whisper" personality card or an All-In-One version of the "Wings" personality card. It was the last Macintosh to ship with an internal floppy disk drive.
The Macintosh can only support one external drive, limiting the number of floppy disks mounted at once to two, but both Apple and third party manufacturers developed external hard drives that connected to the Mac's floppy disk port, which had pass-through ports to accommodate daisy-chaining the external disk drive. Apple's Hard Disk 20 can ...
The ProFile could not be used on the Macintosh or the Apple IIc (for which Apple never offered an external hard disk drive of any kind). By September 1986, the ProFile would be superseded by the introduction of the first cross-platform Hard Disk 20SC SCSI -based drive for the Macintosh and interface card for the Apple II family (excluding the ...
The necessary files of the operating system and default applications must be copied to the USB flash drive Language and keyboard files (if used) must be written to the USB flash drive USB support in the BIOS’s boot menu (although there are ways to get around this; actual use of a CD or DVD can allow the user to choose if the medium can later ...
Device configuration overlay (DCO) is a hidden area on many of today's hard disk drives (HDDs). Usually when information is stored in either the DCO or host protected area (HPA), it is not accessible by the BIOS (or UEFI), OS, or the user. However, certain tools can be used to modify the HPA or DCO.
Fusion Drive remains available in subsequent models of these computers, but was not expanded to other Apple devices: the latest MacBook and Mac Pro models use exclusively flash storage, and while this was an optional upgrade for the mid-2012 non-Retina MacBook Pro discontinued by Apple, it replaced the standard hard disk drive in October 2021 ...
A stock Mac 128K with the original 64K ROM is incompatible with either Apple's external 800 KB drive with the Hierarchical File System or Apple's Hard Disk 20. A Mac 128K that has been upgraded with the newer 128 KB ROM (called a Macintosh 128Ke) can use internal and external 800 KB drives with HFS, as well as the HD20.
The Hard Disk 20 (or HD20, as it was known colloquially) contains a 20 MB 3.5" Rodime hard disk which provides over 50 times the data storage of the stock 400 kB disk drive. At the time when the average file size was around 10-20 kB and due to the vast number of those files the HD20 can contain, Apple's original Macintosh File System , which ...
