I work for a manufacturer and we have been sucessfully using the SanDisk Ultra II (2GB and 1GB) cards for data storage in a couple of our products for several years. (Using software purchased from SanDisk)
Unfortunately, our instruments are unable to work with the new Ultra Cards or the latest version of the Ultra II cards (the ones that don’t have the red wave on the bottom and the silver wave at the top of the front label). We are seeing frequent, intermittent failures especially during file delete operations and to a lesser degree file write operations.
Does anyone know what has changed or if there is something that we can do to allow these new cards to work identically to the older Ultra II cards?
