![]() The outside of the disk is made with rigid, not soft, plastic. There is also a metal tab called a shutter than moves to the side once it is in a computer to give the machine access to the data. The device has a metal piece in the center, called a hub, which holds the disk in place while it spins. The covering is typically lined with a lightweight fabric designed to remove dust particles.Ī 3 ½-inch disk is a little different. The disk is put inside a protective covering, also made with plastic, to keep it safe from harm. The plastic is cut into a disk so it can spin around and retrieve bits of data stored in concentric rings (similar to a vinyl record). The iron allows the 0s and 1s that make up computer data to be magnetically imprinted and retrieved. (The same type of plastic is used to make the ribbon used in cassette and VHS tapes). What is a floppy disk made of?A 5 ¼-inch floppy disk is made with an inner layer of Mylar plastic, a type of PET, coated with iron oxide. ![]() So, unless you are prepared to sew yourself a floppy disk tote bag, the only thing to do with them is send them to a qualified recycler. While a few creative minds have put them to use in craft projects, no one uses them for file storage anymore. ![]() With the invention of better devices that could store more data, such as CDs and flash drives, floppy disks were added to the long list of obsolete electronics. It might be hard to believe now, but the 5¼-inch floppy disk, then the 3½-inch disk, was once the pinnacle of data storage. If that computer is more than 20 years old, chances are there is a box of floppy disks sitting right beside it.

The following table lists the most common media descriptor bytes:įE 1.2 MB 8-inch, 2-sided, double-density Floppy disk reader best buy professional#DiskProbe (Dskprobe.exe) is included with the Windows Support Tools for Windows XP Professional and Windows XP 64-Bit Edition, the Windows 2000 Support Tools, and Windows NT 4.0 Resource Kit Support Tools. For example, you can use the DiskProbe tool to do this on a Windows NT 4.0-based, Windows 2000-based, Windows XP-based, or Windows Server 2003-based computer. To work around this problem, use a disk sector editor to change the BPB media descriptor byte to the appropriate value. Therefore, you can damage or permanently overwrite critical on-disk data structures. This provides you direct access to every byte on the physical disk regardless of access credentials. Disk sector editors function at a level "below" the file system, so the typical checks for maintaining disk consistency do not apply. Misuse of a disk sector editor may make all the data on the drive or volume permanently inaccessible. This workaround involves using a disk sector editor to modify the media descriptor byte on the floppy disk. Warning: This workaround is for advanced users only. To resolve this problem, re-format the floppy disk with Windows 98, Windows Millennium Edition, Windows NT, Windows 2000, Windows XP, or Windows Server 2003. The media descriptor byte is located in the BPB of the boot sector at offset 21 (15h) and in the first byte of each FAT on the disk. Therefore this problem does not occur with these older operating systems. ![]() With MS-DOS and Windows 95, you do not have to set the media descriptor byte. The media descriptor indicates the type of medium currently in a drive. ![]() Older product disks may also not have the media descriptor byte. Some older preformatted floppy disks do not contain a media descriptor byte. This problem occurs on disks that do not contain a media descriptor byte in the BIOS parameter block (BPB) of the boot sector. The same disk may work correctly with MS-DOS or Windows 95, or after you re-format the disk with Windows 98, Windows Millennium Edition, Windows NT, Windows 2000, Windows XP, or Windows Server 2003. STOP: The disk media is not recognized, it may not be formatted. ![]()
