Subject to supplier's pricing. 400K DisksThe problem was when I tried to 'format' my Mac, during the re-installation of the O.S, a message appeared in my screen saying that the 'Recovery partition could not be created', that was weird for me, I am not very good with my Mac yet, so I tried using a OS X Lion installer (which is in a CD), I tried to install from the CD (what many people. The short answer is, it depends. Mac OSX and Linux users are recommended to use a Virtual Machine to run the.Earlier today in the Apple Macintosh Enthusiasts Facebook group, Charles Lott asked if an OS X Mac with a USB floppy drive could write disks that a Mac running System 7 could use. As the ideal Format Factory alternative for Mac, Bigasoft Total Video Converter for Mac supports almost all the functions and features that Format Factory provides besides, this powerful Format Factory Mac software can do what Format Factory cannot do: Work on Mac OS X 10.4(Tiger), 10.5(Leopard), 10.6(Snow Leopard), 10.7(Lion), and EDI X12 is an Electronic Data Interchange format based on ASC X12 standards.In the Recovery app window, select Disk Utility, then click Continue. (This is also the reason non-Mac computers can’t mount 400K and 800K Mac floppy disks.)On an Intel-based Mac: Choose Apple menu > Restart, then immediately press and hold Command-R. These drives had a variable speed motor that allowed the Mac to pack 400K into a disk that would only hold 360 KB on a fixed-speed drive. The original Mac floppy disk format was MFS, for Macintosh File System, and it is only used for 400K single-sided floppies – the only kind of floppy drive supported by the original Macintosh, the Mac 512K Fat Mac, and the Lisa 2 (a.k.a. Tube 56 276 250/5.6 CF 2398.
Click Erase and enter your Apple ID if required. Format: Disk Utility shows the recommended Mac format by default. Type a name for the volume in the Name field, click the Format pop-up menu and. (HFS had been introduced in 1985 to support Apple’s first Mac hard drive, the 20 MB Hard Disk 20, which connected via the slow floppy disk port. 800K DisksWhen Apple introduced the Mac Plus in January 1986, it adopted double-sided floppy drives with 800K capacity – and a newer disk format known as HFS, for Hierarchical File System. (There is also a 20 MB maximum volume size for MFS hard drives.)All Mac OS versions up to System 7.1 support formatting 400K floppy disks. Disk access is controlled by code in the system ROMs, and that can’t be updated to support double-sided drives. There is no support at all for 400K floppy disks in Mac OS 8 and beyond.There is also no support for floppy disks with greater than 400K capacity in those original three models. Under Mac OS 7.6 and 7.6.1, they can read 400K floppies but not write to them. ![]() That meant the operating system would have to cluster more than one 512 byte chunk of data into an allocation block. In the era of small hard drives, it didn’t matter, because whether you were using a floppy disk, a hard drive, or a removable media ( SyQuest, Zip, etc.) drive, they all used the same size block of data – 512 Bytes (0.5 KB).Or did they? Another limitation of HFS is that it cannot work with more than 65,535 files or blocks of data. Mac OS 8.1: HFS+ Makes More Efficient Use of Disk SpaceAs hard drives grew in capacity, some limitations of the HFS format became apparent. Every version of the Classic Mac OS from System 3 through 9.2.2 can read, write, and format 800K and 1.4 MB floppy disks as long as the mechanism is an Apple FDHD or a third-party Mac-compatible drive with a variable speed motor.Macs with high-density Apple floppy drives and System 3 through Mac OS 9.2.2 support formatting 1.4 MB floppy disks. Below 32 MB of so, HFS and HFS+ both use 512 byte allocation blocks.Alsoft created PlusOptimizer to convert HFS hard drives to HFS+ format.And what does this have to do with floppy disks? Keep reading, because HFS+ floppies became a possibility in the era of USB floppy drives! Macs Without Floppy Drives: The iMac Generation 1.4 MB Only (Sort of)One of the chief faults of the iMac when Steve Jobs unveiled it in May 1998, according to most critics, was its lack of a built-in floppy drive. That means that a 500 MB drive or partition will still use 512 Byte allocation blocks, a 1 GB drive will double that to 1024 Bytes (2 x 512), and so on.Under HFS, that began to happen once hard drives passed the 30 MB mark, so HFS+ made for much more efficient use of data space. HFS+ supports over 4 billion allocation blocks. Format Book Os X For Resale Drivers For TheIt does support USB floppy drives, and it would normally format them as HFS disks – although there were some changes over time.Siber-Sonic, who used to work for Apple, did extensive research of this subject, answering the question, “If I format a HD floppy disk in a USB floppy drive, what format with OS X use? Also, do all versions of OS X support HFS floppies?” HFS Floppies: Fully Readable, No Writes with OS X 10.6 or LaterThe good news is that all tested versions of Mac OS X are able to read 1.4 MB floppy disks in a USB floppy drive. Mac OS X Changed EverythingWhen Apple introduced Mac OS X, one thing it didn’t do is provide drivers for the Mac’s internal floppy drives. On the other hand, it’s a pain to use with Macs, which don’t expect that format. Fortunately all but the oldest Macs support HD floppies, but the expense of an external USB floppy drive was discouraging to many longtime Mac users – and potential iMac adopters.Another option was to use Apple’s software to format a double-sided, double-density floppy to 720K instead of 800K, in which case most USB floppy drives can read and write to it. You had to buy a USB floppy drive to read the disk from your other computer.Problem is, none of these USB floppy drives have the variable speed motor necessary to read the Mac’s 800K disks, so you had to be sure to use 1.4 MB HD floppies (or 720K floppies in the case of PCs with 3.5″ floppy drives). Android emulator macWhat About More Modern Macs and Mac OS Versions?Siber-Sonic found that under OS X 10.8 Mountain Lion, although the operating system can read and write HFS+ floppies, the only options for formatting are the FAT and ex-FAT formats used in the Windows world. Regardless, at least you have a floppy disk you can use in current Macs as well as vintage ones running Mac OS 8.1, the first with HFS+, and later. HFS+ Floppies: Full Compatible with All Versions of Mac OS XUnder OS X 10.6 or earlier, the default format when formatting a floppy disk is HFS, but earlier versions (at least back to 10.4 Tiger) let you choose HFS+ as your disk format.1.4 MB floppy disk formatted as HFS+ has 1.3 MB available space.Would you have guessed that an HFS+ floppy would have less available storage space than an HFS disk? Roughly 123 KB of additional space is used by the file system. To do that, you need to use OS X 10.5 Leopard or earlier. They are not compatible with any version of Mac OS X.1.4 MB HFS floppy disks require an Apple FDHD, Mac-compatible HD floppy drive, or USB floppy drive. These can be used in any Mac with an 800K of FDHD floppy drive with System 3 through Mac OS 9.2.2. You cannot access them at all in Mac OS 8.0 or newer800K floppy disks also require an Apple branded or Mac-compatible floppy drive with a variable speed motor. You can write to them through System 7.5.5 and read them through Mac OS 7.6.1. OS X 10.6 and 10.7 will let you erase an HFS floppy, but they will only format floppy disks as HFS+. Later versions of OS X can read but not write to them.Finally, 1.4 MB HFS+ floppy disks can be fully accessed from Mac OS 8.1 forward, although OS X 10.8 Mountain Lion and later will not let you format an HFS+ floppy. You can write to them using System 3.0 through Mac OS X 10.5 Leopard.
