I seem to be having problems with my sd card... i have a sandisk pcmcia sd card reader and it keeps erasing itself. I used it primarily in my pocket pc and now i'm going to swap it between my treo and ipaq. so to do so i had to reformat it from FAT32 to FAT for it to be seen in the treo. so i copied all the file to my hard drive- formatted the card in windows xp and copied all the files back to the card. i put the card in my ipaq and there are no files on it. i put it back into the card reader and it is still formatted as fat32 and has no volume label. the same thing has happened twice now and i'm wondering if anyone has any suggestions as to fix this...
