Old topic, but relevant to my current issue:
I just got one of these for my D70s:
on the packaging it states it can work with MMC cards. I still have an old 4Gb MMC I used in a car radio, so wanted to use this in the adapter on the D70s (I bought a 2Gb CF with the camera).
I can not get it to work with the MMC card in it, it works perfectly with a 4Gb SD card (indicates 700+ possible pictures).
Any inspiration what I could try, till now:
- Format in the camera (with buttons and through menu) just leads to "For" on the indication of the number of pictures
- Format in computer: through the adapter also gives nothing, it shows not formatted card, proposes to format and states can not format at the end.
- Format MMC in D7000: states "Card Err" (not unexpected)
- Format of the MMC to FAT in computer (was FAT32) did not change any of the above tests.
At least I have a backup solution now with SD cards for the D70s and a way to read SD in the computer should my SD reader wear out (seems to have issues sometimes).
