Hi There,
I am using Big Sur 11.5 on a MacBook Pro 2019 model.
One of my Seagate Backup Plus Slim 5TB got corrupted so I backed up the data through a recovery software.
However after the backup while trying to Erase and create a new filesystem layout (APFS or any other) through diskutility gives an internal error -69488.
Can you please guide if there is a way out?
Thanks,
MacBook Pro 15″, 11.4
Well, that additional information would have helped if disclosed in first posting. Failure to provide accurate and complete information will led to inaccurate assistance.
Would suggest Repartitioning the Drive as Single partition and then reformat as HFS Journaled with GUID Partition Map. Then reformat to APFS again with GUID Partition Map.
If that does not work - the drive may have failed as they do from time to time.

No it is an external media.
What the picture above is trying to Erase your Internal Drive " Erasing "AppleAPFSMedia " and not the Seagate drive. Be thankful the eases did not go through
