If you have the Qic117.sys driver installed and your Floppy drive is alway inaccessible, check Control Panel / Devices for your device. If Startup is set to SYSTEM, change it to automatic and reboot.

When the driver loads, your floppy device is disabled. Changing the startup to automatic prevents the driver from loading until the backup program does a Tape Device/Detect. Your Floppy won't be usable after a backup until you reboot. The Qic117.sys driver is used by the following devices:

HP Colorado T3000
HP Colorado T1000
Wangtek QIC-3010 floppy
