Not on the i5, your best bet is to use a recovery software or send the tape to a company that specializes in data recovery.

I must say that after the command is recorded 2 libraries.

Just in case there’s an obscured element in there, can you please explain that statement a little more?

Thanks for your help. Do you know any software that retrieves information from the tape.

About the 2 libraries, it mean somebody else save 2 libraries after this mistake

…somebody else save 2 libraries after this mistake

If objects have been saved to that tape after it was initialized, it’s far more difficult. Blocks that are physically present somewhere past the the latest tape marks could be recovered by a competent recovery service. At least some of those blocks will probably be meaningless if earlier blocks are needed to complete them.

Any blocks that have been overwritten near the beginning of the tape stream will require the very best recovery services and won’t guarantee useful results. You almost certainly don’t want to pay for recovery of anything that was overwritten; that level of cost is usually prohibitive.

Personally, I’d view the previous content as totally lost unless the fate of the business truly depended on it. (Even then I’d hesitate.)
