![]() While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater data storage capacity and data transfer speed, such as USB flash drives, memory cards, optical discs, and storage available through local computer networks and cloud storage. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.įloppy disks were so common in late 20th-century culture that many electronic and software programs continue to use save icons that look like floppy disks well into the 21st century, as a form of skeuomorphic design. The same is true for an external USB floppy drive connected to a Mac. Please note that a PC floppy drive cannot handle 800K Mac floppies. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. A Windows PC can be used to read 1.44 MB Mac-formatted floppies, but that would require a special utility (such as TransMac). Youll either need a real Apple variable speed drive, or something like Kryoflux or a similar system. A standard USB external floppy for IBM-PC floppies cant read this. ![]() 3½-inch floppy disks can still be used with an external USB floppy disk drive. The 400K/800K Macintosh floppy disks use a variable speed system, where different parts of the disk are written at different densities. Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. The first floppy disks, invented and made by IBM, had a disk diameter of 8 inches (203.2 mm). To me, that suggests that the issue is not that the BIOS needs an 'IBM-formatted' floppy, but one that was not formatted by a Windows NT-based operating system. Do not use a floppy disk that has been formatted in these operating systems. 8-inch, 5 + 1 ⁄ 4-inch, and 3 + 1 ⁄ 2-inch floppy disks 8-inch, 5 + 1 ⁄ 4-inch (full height), and 3 + 1 ⁄ 2-inch drives A 3 + 1 ⁄ 2-inch floppy disk removed from its housing Note: Do not format the floppy disk in Microsoft Window NT(r), Windows 2000, or Windows XP.
