As of early 2007, the simultaneous availability of non-standard 4 GB SD and of standards-compliant 4 GB SDHC cards, and incompatibilities between SD and SDHC have caused confusion among consumers buying memory devices.

As of early 2007, the simultaneous availability of non-standard 4 GB SD and of standards-compliant 4 GB SDHC cards, and incompatibilities between SD and SDHC have caused confusion among consumers buying memory devices.
SD and SDHC cards and devices have these compatibility issues :
- Devices that do not specifically support SDHC do not recognize SDHC memory cards.
- Some manufacturers have produced 4 GB SD cards that conform to neither the SD2.0/SDHC spec nor existing SD devices. [16]
- File System: SD cards are typically formatted with the FAT16 file system, while SDHC cards are typically formatted as FAT32. [17] However, both types of cards can support other general-purpose filesystems, such as UFS2/ext2 for example.
C'est mon cas, mais étant un peu loin ...
Allez,
