Files not being read by MacOS Sequoia but are on Ventura - then they're not.

Does the same card adaptor work in the MacBook Pro? Can you try the card in another card reader in the Mac mini?

What format is the card (FAT, exFAT and MBR or GUID?) and on which device was it formatted and when? I usually always reformat cards inside the DJI drone before taking off because the camera device knows best what format it prefers (of course after importing and making a backup on the Mac). It has worked OK but Sequoia might be picky about FAT/exFAT, and if that is the case I'd try if formatting on the Mac makes a difference.

Hi,

I've recently had delivered am M4 Mac Mini running Sequoia

when I attached my micro sd cad into the Mac mini using an adaptor as there's no sd card slot, I received this message; "The disk you attached was not readable by this computer". The card was working fine in Ventura, I have a MacBook Pro currently running Ventura and this gets the same error message with the same card.

When I attached a different micro sd card into the MacBook Pro the card is read easily and all the files are there from previous flights.

Now this where the problem continues. When I attach the same card to the Mac Mini with Sequoia I then get the error message. When I went back to the MacBook Pro, I find that the same sd card now can't be read and the sd card shows the same error message "Eject", "Ignore" or "Initialise".

Surely, the Mac Mini somehow hasn't short circuited both of my sd cards or adaptor ?

Can anyone help me on this ? VERY much appreciated if you can.

Thanks,

formatted how?

An external card reader has been the recommendation as a work-a-round...

you can try a different SDcard and compare your resuts...
