Sony MSFD-20U Floppy Disk Drive FAQ - Page 3

What causes a Non-System Disk Error? A Non-System Disk Error results when the Basic Input/Output System (BIOS) cannot find the boot sector, or the master boot record is missing or damaged; the device does not have bootable media. The BIOS searches drives in the order specified in the CMOS setup. This order is often, but not always, A: (floppy drive), C: (first partition on the hard disk). The error normally occurs during startup if the CMOS is set for the BIOS to seek the floppy drive first and a non-bootable (or blank) floppy is in the floppy drive. Other possible causes include:  No bootable partition on a hard disk drive  A defective hard disk drive  The CMOS drive settings (parameters) are not correct for the boot device  Defective floppy  Defective floppy drive  A virus When used with a Macintosh® computer, an error occurs that says the USB Floppy Drive cannot operate because it needs more power. This indicates that you may have plugged the floppy drive into a USB port on a Hub or keyboard. The device must be plugged directly to the USB port on the computer. It is not supported on a hub or when connected to a keyboard. An icon does not appear on the desktop when the floppy drive is connected to a Macintosh computer. The drive does not display an icon on the computer desktop until a floppy disk is inserted in the drive. I cannot format a floppy disk to 720 K with a Windows XP operating system. The ability to format floppy disks to a capacity of 720 K is not available in the Windows XP operating system.
