SYMPTOMS

When an LS-240 (high-capacity floppy disk) drive is "hot swapped" by a CD-ROM drive, an extra icon may be displayed in My Computer and Windows Explorer. Device Manager also displays two CD-ROM devices. This problem disappears when you restart the system with the CD-ROM drive.

CAUSE

This problem can occur if a code problem in the Atapi.sys file prevents the logical unit numbers (LUNs) from being reset when a multi-LUN device is replaced by a single LUN device.
