This is a Sony Cyber-shot DSC-F828, and its storage media is a CF card.
Since it’s an old digital camera, some don’t recognize CF or SD cards, apparently.
In situations like this, buyer reviews really come in handy.

JPEG Fine mode works without issues,
but RAW writes slowly. ★
If you’re shooting one frame at a time, it’s great. ★
