Looks like the tape drive has failed on the Definity Audix at one of my sites. Get a minor and warning alrams 1 and 4. Try to add tape and tells me hardware unit fault. Test tape fails, add tape first. Tried replacing tapes to no avail. Tried cleaning drive to no avail. Any suggestions. I do have another definity Audix unit in my parts box. Can I just swap out the tape drives? Any help would be greatly appreciated. Looking to try this over the weekend since Audix still seems to be working. But for how long no one knows with nightly storms and power outages.
