Archived from the original on Whereas semiconductor memory naturally favors powers of two size doubles each time an address pin is added to the integrated circuit , the capacity of a disk drive is the product of sector size, sectors per track, tracks per side and sides which in hard disk drives with multiple platters can be greater than 2. The drive usually has a button that when pressed ejects the disk with varying degrees of force, the discrepancy due to the ejection force provided by the spring of the shutter. Minimum monthly payments are required. Two holes at the bottom left and right indicate whether the disk is write-protected and whether it is high-density; these holes are spaced as far apart as the holes in punched A4 paper, allowing write-protected high-density floppies to be clipped into standard ring binders. Later soft- sectored disks have only one index hole, and sector position is determined by the disk controller or low-level software from patterns marking the start of a sector. Small protrusions, indentations, and cutouts, prevent the diskette from being inserted backward or upside down:

Insurance is required on most items. Failure of this mechanical switch is a common source diskettee disk corruption if a disk is changed and the drive and hence the operating system fails to notice.

Usable data capacity is a function of the disk format used, which in turn is determined by the FDD controller and its settings.

Apple implemented this in early Macintosh computers by spinning the disk more slowly when the head was at the edge, while maintaining the data rate, allowing KB of storage per side and an extra 80 KB on a diwkette disk.

One of the chief usability 0p5222 of the floppy disk is its vulnerability; even inside a closed plastic housing, the disk medium is highly sensitive to dust, condensation and temperature extremes. The floppy disk symbol is still used by software on user-interface elements related to saving files, such as the release of Microsoft Officeeven though the physical floppy disks are largely obsolete.
As opposed to other solutions, no new drive type or special software was required that impeded adoption, since all that was necessary was an already common USB -port.
