Hi,
I am trying to read a 4gb SD HD card class 6 [hispeed], and Centos

Any suggestion?
My understanding is that the HSSD/SDHC cards have somehow changed the
methodology of how the cards are formatted (or somesuch).
indeed, the SD specification has a 2GB max physical limit, SDHC (SD
High Capacity) changes how the registers are used to allow larger
cards. This is somewhat akin to how the ATA/IDE spec had to be
extended over and over to support ever larger disks, most recently the
LBA48 spec to get past the 128GB wall.
