no appendable (end marker unreadable)

This issue has been solved. See solution.


I have a tape that has no appendable (end marker unreadable) in its property and I cannot use it for backup and I understand that I have to reformat this tape.

but this tape has some new data on it and I must keep them. so I muse duplicate it on other tape. we have a tape librery with one drive. the tape that must be duplicated sys this:

used capacity: 348 GB

Data: 650 GB.

I think to do a data Duplicate first the data must be writen to the Hard drive and then to a new tape. but my question is, how mauch free space on the Hard drive Do I need? does the Hard drive must have 348 GB free space or 650 GB free space?

Your HDD needs as much free space as you have written to disk with no compression. If you wrote 400GB to tape with 1:2 compression for instance, this equates to 480GB on disk...

Duplicate to disk, and from there backup to tape as you have stated.
