TL;DR: See the attached picture. Has anybody got a this Micro SDXC class 10 with 1 TB working in a PinePhone or PineBook? Could this be a PAGHY card?
I bought this card around May 2021 after I got the PinePhone in April 2021. My intention is to have a multi-distribution card as described on https://wiki.pine64.org/wiki/PinePhone_P...sing_rk2aw for the PinePhone Pro. In the time before last week I was busy with other things so the card wasn't really used much.
During the preparations several problems occured.
The first hint is "Alternate GPT is invalid, using primary GPT".
