After getting 0xa0008115 errors, I disabled and deleted the device and restarted the service. The devices were recognized fine, but now when I try to run a backup it eventually goes to queued and gives the alert, "please insert overwritable media". I am using the same media as before, but is shows up in the offline media and the tapes all have a new default media label listed under slots. I didinventory the media also. It says they are not appendable, but overwritable. I am not sure what to do or in what slot to insert new media into if this is what is needed. I am running Windows 2000, a Dell Powervault 122T with 7 tapes and 1 cleaning tape.
