SDHC cards require SDHC-capable device firmware generally not found with older devices.
SD and SDHC cards and devices have these compatibility issues :
Devices that do not specifically support SDHC do not recognize SDHC memory cards.
SDHC devices are backward compatible with SD memory cards.
Some manufacturers have produced 4 GB SD cards that conform to neither the SD2.0/SDHC spec nor existing SD devices.
File System: SD cards are typically formatted with the FAT16 file system, while SDHC cards are typically formatted as FAT32. However, both types of cards can support other general-purpose file systems, such as UFS2/ext2 or the proprietary exFAT for example.
If your device can handle SDHC, buy that kind of card. If it cannot, you might be able to upgrade via a reflash of the bios. Please contact your manufacturer for more details.
