I am using a Sony SDX-500V AIT SCSI Tape drive on a server 2003. At the end of 2008 we installed the Symantec Backup Exec 12 for Windows Servers. In mid October our tapes started ejecting by themselves and we have not had a good backup since. I have tried multiple different tapes. I have checked to make sure that the over write feature is on, & the jeject upon completion is not checked. I've made sure that there are no updates.
What is happening is, I put the tape into the drive & sometimes it ejects right away and other times it looks like it is preparing a backup & will run for quite a long time but then ejects by itself. I have canceled the scheduled job, and restarted. I have canceled the job & ran an inventory & it is completing that successfully. I've tried running a test & it fails every time.
Can anyone recommend a solution for the tape ejecting over, & over & over again?
