What's the difference between some of the SD/MMC cards so that some work and some don't? I bought a 1 GB MMC card and it works fine on Windows, but not in my SL-C860 Zaurus. The Zaurus can physically access every single bit on the card (surface scan returned perfectly), but as a mounted VFAT file system it has trouble writing to the card.
(See these links for more details).
2nd Thread (much more advanced and technical)
My question is, what's the difference between the various MMC cards that make some work and some don't. Ditto' on the SD cards. I thought they all were part of a standard and that the hardware physically couldn't tell the difference between MMC card A and MMC card B if they are both the same size. ...but this doesn't appear to be true.
So... what are the differences? Why does the Linux driver work with some and not with others?
Also, is there an update driver in the works to fix this? (So the links above for more stats and debug information on my situtation).
