On the latest SANDisk batch of CFs I got, I am getting periodic errors reading from the flash on my 5501 (FreeBSD RELENG_8).  However, when I put the flash in different readers-- e.g. attached to a regular server, no errors.  On the 5501 I get periodic

the 2G flashes work just fine in the same box.  The only difference I can see between the 2G and 4G CF is that that atacontrol says "lba48 supported".... Could this be the issue ? If so, is there a way to turn it off or work around it ?  My supplier is not carrying 2G anymore and the 4 is the same price as the 2G :(
