Hi,
I am trying to read a 4gb SD HD card class 6 [hispeed], and Centos 5.1 does not recognize it. ... 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.
