    bpexpdate only deletes information from NBU catalog. It does not format or do anything to the media. In other words, old backup data and the previous internal label is not wiped or overwritten. When the tape is about to be re-used, only backup data is overwritten, not the internal label. 
    When NBU sees another internal label that does not match the media-id, if freezes the media. This is perfectly normal as it may be media from another environment with valid data and someone has stuck another label on the tape.

    See Option 2 in my previous post:

    Relabel the LTO4 media to match current Media ID Generation behaviour:
    Unfreeze media, then use Label option to overwrite internal label. De-select 'Verify label' tick-box.

Hi,

yes you're correct, in the physical label, the label is EPM031L4, but in NBU this was just show M031L4.

and honestly, this tape has been used for backup before, but i have format it using bpexpdate and i thought that was enough.

So, would you please to tell me about step by step to fix it? i really really need your help dude.

i've change it to HCART again btw.

Thanks
