I:frown: bought a SanDisk 1 GB RS-MMC (at a local retailer, who used it himself too). First I made a backup to this card and it worked (once).:frown: Now it will not do anything anymore, no copying files to the card, no (new) back-up, nor can it be formatted (write error). Re-booting, removing the card and putting it back - nothing helps. It is visible in the as D:\Name. Please help!
