So I do a fresh install of BE (Server 2008 R2 64bit), drop four LTO4 tapes in my Dell 124T, Initialize the Library, do an Inventory and Import the four tapes. Now I have my tapes listed under "scratch media", however, under Media description, they all say "Unrecognized Media". When I try To run a backup job I get "The media labeled '000030L4', from slot '13', read by drive 'IBM 0001' is written in an unrecognized format. Erase the media to make it usable." and then "Please insert overwritable media into the robotic library using the import command."
Yes, I've tried erasing the media but to no avail. These are completely new tapes. What am I missing here?
