i believe Samsung uses a proprietary file system with SDHC cards…i have a 2GB card that the Rogue formats into fat32 and a SanDisk 16GB card that i can’t seem to be able to reformat into a standard file system. Windows 7 nor Ubuntu 10.04 can read the files on my 16gig card. the best way i have found getting files on or off the phone is via Bluetooth. i’m currently looking for an app that can reformat this card into fat32 or NTFS…maybe a smart cookie at SanDisk can help us out =]
