You need to get the files off the floppy. Xx <- This byte above XX is the media descriptorīyte and is at offset hexadecimal 21 (15h).įor additional information, click the following article number to view the article in the Microsoft Knowledge Base:ģ01423 HOW TO: Install the Windows 2000 Support Tools to a Windows 2000 Server-Based Computerģ06794 How to Install the Support Tools from the Windows XP CD-ROMĢ06848 Windows NT Service Pack 4.Will Dolet work on anything that old? But we don't know what version of Finale this is. The following table lists the most common media descriptor bytes:įE 1.2 MB 8-inch, 2-sided, double-density 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.
