I have a Nikon Z 50 and, just like it happened with the previous D7100 and D40, the SD card I use in it is readable under Windows 10 by using a normal SD card reader. The same happens with other cameras using the same physical SD card.
The SD card (maybe SDHC, surely not SDXC) is a Sandisk 8 GB from some years ago, rated about 45-60 MB/s so not the cheapest series back then (and still today).
That same card formatted on the Z 50 is not recognised by a D800 (firmware A/B 1.10) and, once formatted in the D800, is not readable at all under Windows 10, which only sees in Disk manager the presence of a partition, but not the type of partition and obviously not the content. It does not even appear in "My computer" as unreadable, which is often the case when a wrong disk format is used (like a card formatted for linux or Mac).
I am forced to use a USB cable to download photos from the D800.
Why is that? how to solve this issue?
