no one uses floopy disks anymore
The floppy disk which is commonly referred to as a high density floppy disk is a 3.5 inch disk. It has a storage capacity of 1.44 MB.
A standard high density double-sided floppy disk holds about 1.44 mb.
There are no tracks on it until you put tracks on it.
224 for a 3 1/2 inch floppy
A 5.25-inch floppy disk typically has a storage capacity of 360 KB to 1.2 MB, depending on the specific format used. The most common version, the double-sided, double-density (DSDD) disk, can store 360 KB, while the high-density (DSHD) version can hold up to 1.2 MB. These capacities are significantly lower than modern storage media, which can hold gigabytes or terabytes of data.
The most common ones most people are familiar with were 1.44MB, but there were many sizes of "floppy disk" from about a hundred kilobytes to a couple hundred megabytes. Nowadays, the answer is 1.44 for a double sided high density 3.5" floppy disk. This answer is quite different for other types of floppy disks. There are single sided, double sided, single density, double density, high density , 5.25", 3.5", and 8" floppy disks just to name a few of the many, MANY variations. * low density capacity: 360 kbytes * hi density capacity : 720 kbytes * double hi density: 1.44 megabytes There are other (rare) formats that can hold more.
Last century when desktop computers were invented they stored information on floppy disks. The last of the floppy disk to be used could take 1.44Megabyte. These days we have USB drives which will take 8Gigabyte or about 7 000 times a high density diskette
4mb unformatted, 2.88mb formatted (depending on format, of course). Toshiba made a model PMF-2ED "4MB Extra High Density" also marked "ED". Here is a picture of one: http://www.zimmers.net/tmpsampleeddisk.jpg (I'm fixing to auction 110 of them, so I googled around to find out how common they were).
Magnetic storage has come a long way since 1967 when IBM developed the 8-inch floppy disk. However, I assume you are referring to the 5 1/4 floppy that came out in 1976 and the 3 1/2 high-density disk that came out in 1987. The three major differences between these two disks are the physical size, the storage size, and the speed. The 3 1/2 disks were much quicker, smaller in size, and held more data.
There is no 5.14 floppy. A 5.25 or 5 1/4 inch 80‑track high-density floppy can store 1.2 megabytes of data. The older 40 track floppy drives were able to store 360 kilobytes.
As the media and Floppy (Floppies) disk readers technology improved the data capacity improved. The latest and highest floppy disk capacity reached 2.8 Mb. (IBM) but never became a popular size. From latest to earlier sizes ( inches relate to the size of the media ) 3.5" Floppy disk 1.44 Mb. , was called double or high density disk - " in common use for a long time. 3.5" 720 Kb. , single density disk 5.25" 1.2 Mb. ( Paper / non rigid PVC cover ) 5.25" 720 Kb. 5.25" 360 Kb. Common with earliest PC's around 1990 5.25" 180 Kb. other sizes were also used for non standard Computers ie.:" IBM Mainframe computer" 8" 360 Kb. 8" 180 Kb. Other disks that looked like 3.5" size Floppy disks, but contained a more rigid media disk and a stronger 3.5" enclosure , are called Zip disks with capacities up to 120 MB
Most likely, you are confusing a 1.44 MB (HD) floppy disk with an even older 720 KB (DD) disk. These had only half the capacity, but are otherwise functionally identical. These disks can be distinguished by their lacking a hole on the lower right-hand side that newer floppy disks do. It is also possible that your BIOS is set up incorrectly so that the drive operates as a double-density drive instead of the correct high-density drive.
