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. The Windows XP operating system only supports the formatting of
floppy disks to the 1.44 MB capacity. If necessary, contact Microsoft for further
information.
