I finally got around to picking up a Sandisk 64GB card today. After I ran a quick scan of active sectors it didn't report anything after sector $1..0200 but it would have taken a few hours maybe although it got through well over a 1GB in about 10 minutes just finding active sectors and then dumping the first 16 bytes for reference.

Anyway, I was really more interested in formatting these cards to FAT32 using my new disk utilities. So it works really well and it's fast. I just typed "0 FORMAT" to select automatic cluster sizing which in this case would be the maximum 64kB clusters.

Here's what my PC saw the card as:
FAT32-64GB.png

Remounting the card after checking and loading files from the PC then backing up the system to a file which is then renamed and the system rebooted.

    Excellent job Peter. Sorry I didn’t get to test this for you.

    BTW I just cracked reading exFAT. I’ll put it into my SD code ready in case there is a chance to update the ROM. There is the silly -2 clusters as a base from the DIR.
