Funny you should mention SanDisk. Maybe the newer ones have gotten better but the CF cards I used in my PDA were mixes of the SanDisk 128 Meg and SimpleTech 128 Meg. Burned up several before I realized it was the nightly backup program that was eating them and I didn't notice any difference between the brands. I don't know what controller was in the SimpleTech CF cards. Any way to tell short of dismantling them?
