It is good to know the reason for the same SD card having different IDs in different devices. So I am also thankful for Jeff's description. However I don't think the "8 digits after the _" rule still applies to all SD makes. For example, the SD card ID for the 1 GB Lexar Platinum 40x does not have a '_' character. - Greg -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
