SDHC SD Card

I think only SD cards will work, not SDHC.

From Wiki:
SDHC uses the same form factor as SD, but the SD 2.0 standard in SDHC uses a different memory addressing method (sector addressing vs byte addressing).

Basically, a SDHC reader should read both SD & SDHC cards. However, a SD reader will not read SDHC cards.

Many people have reported success with 4GB A-Data SD cards.

I have the Transcent 150x 4GB SD card which works just fine. Never tried an SDHC though.
I thought that all 4GB and larger cards are SDHC because the standard SD cards are limited to 2GB. In general, compatibility for 4GB+ cards are iffy depending on the device. 2GB SD cards in general should have fairly universal compatibility.
Not all 4GB are SDHC. I've seen many 4GB SD cards without the SDHC logo.
