I bought a 2GB Sandisk Ultra II from Staples this morning and it seems to work fine straight out of the bag.
Until I tried formatting it on the Eclipse, when it gave the sort of problems described.
But, I then quick-formatted it on a PC (being sure to select FAT rather than FAT32) and it was fine again. SO, the problem is with the format command on the Eclipse, rather than the read/writing of the card.
We plan to fix the format command in a future version of the software, but until then an easy workaround is to format it on a PC as described above.
Note that there are possible issues with bigger cards (e.g. 4G, 8G) due to the FAT file system running out of abilities to handle them.
