I have been running a rotation of b2d usb drives for about a year with little problems. recently the jobs are going to queued and the status of the drive is active. Each time it creates a 2kb file on the drive. I have treid to cancel and start again numerous time but each time it stays queued and the operation says none. When the job calcels the drive goies boack to online. this is a single 2008 server running 2008 sql server. I have tried using the agent to back up the databases and I have just tried to back up files without not in the database but get the same result.
Any ideas why this would just start after working for so long
