Zpool created on USB HDD not found internally

When I create a pool on a drive in a USB enclosure, this pool can not be imported when connected internally via SATA.
The pool however can be reimported if put back into the enclosure.
Is this a known limitation or is there a solution so I don't have to move 2 TB of data again.
Is there more information I can share that would help solve this problem?

USB controllers can present a different geometry view of the HDD than seen when connected directly.
In which case, the disk will not be readable.

Could you elaborate geometry view? Do you mean block size or location of MBR? Why does it work the other way around (zpool created internally will be detected in the usb case).

Block size difference 4k vs 512e can certainly happen.
Why does it work for you the other way around, no idea.

Thank you. If anyone knows a workaround for this problem could certainly help.
