As per HPCfactor Support article Max Supported SD Sizes
SD Cards larger than 2GB
As a local controller independent technology, Windows CE can theoretically support any size SD card that the device can provide power for, within the file-system limitations of the built-in drivers.
However, changes to the SD Card specification to support storage capacities greater than 2GB may create issues on older hardware.
Older cards smaller than 2GB make use of byte addressing based upon a 32-bit address, where as newer cards supporting sizes greater than 2GB require 32-bit LBA support. Older cards greater than or equal to 2GB may use proprietary addressing techniques and may not offer any compatibility with the reader hardware.
How to correct the issue:
In order to correct the issue, you must locate firmware updates for the SD controller in your device, and, depending on the Windows CE version, driver updates for the controller hardware itself. This applies to all computer system, not just Windows CE.
where or how would i find the firmware for the SD slot on my PSC (Now Datalogic) Falcon Follett 4220-1011 With Windows CE.NET 4.20.
I believe i have a MediaQ mq1188 and i believe the driver name is mq1188sdmmc (as per the registry entry in HKEY_LOCAL_MACHINE\Drivers\mq1188sdmmc) "ScanDisk MultiMediaCard"
unless im mistaken and this is something else.
I Apologize if this should be posted in a hardware section instead.. i wasn't sure which it qualified as.
