pool not found...

[h4ns]

After some time I attached a disk with a truenas pool back to my working system expecting to import the pool.
Unfortunately, no pools were found for import.

zdb -l shows "failed to unpack label 0-3"

Is there a chance to get the pool back?

What's the model of the disk?

What's the model of the disk?

Can’t look now, but it’s some Seagate 2,5” 500GB 7200RPM SATA drive.
I used it for transfer of files and now I need some data from it because of stupid backup settings and limited space on both main & backup pool.
