Why does the RED LED flash once a second at power up ?

The CFSound-III operates the CF cards in memory mapped mode. The Kingston CF cards that utilize the Silicon Motion controller have a firmware bug that causes a doubling of the values read from the card when it is accessed in memory mapped mode. This causes a problem with the results of and completion of the card access cycles, resulting in an ATA error on the CFSound-III - Red LED error code flashing once every second.

Both Kingston and Silicon Motion are aware of the problem and have chosen not to correct it. Kingston has refunded customer's money for purchased 1Gig CF cards that exhibit this problem.

We can no longer recommend Kingston CF cards. We sell and recommend Sandisk CF cards.

We have now heard that 'TwinMOS' CF cards sold by Radio Shack are exhibiting this same problem.

UPDATE: Kingston has actually purchased a CFSound-III and confirmed that their CF cards do have a problem. They have corrected the problem on their 4G CF cards. The corrected Kingston CF cards have the SKU: "CF/4GB-S2". We applaud Kingston for investigating the problem and fixing it. This fix will not be available for their 1GB and 2GB CF cards as they are no longer being manufactured.
