I have a Windows 2008 R2 Server running Backup Exec 2012.
We have been using a Dell TL2000 LTO5 backup drive for the last few years successfully. I have just replaced this with a new Dell TL1000 LTO6 unit. This has installed in Windows successfully (no flags or faults in Device Manager) and I have ran the tapeinst.exe tool to pick it up in Backup Exec.I can see the unit successfully within the software and interact with it.
When I insert one of our new LTO6 tapes (pre-fitted with barcodes from the factory) and run a scan on the magazine slots, the barcode is successfully read and it shows up ok in Backup Exec. However if I try and run a test backup on a small folder (or any other backup operation) I get the following error:
"Media is unrecognized. The media labelled "from slot 9" read by drive "xxxxx" is written in an unrecognised format. Erase the media to make it stable".
Running an erase operation (normal or long) makes no difference. Trying a different tape makes no difference.
Any ideas?
