I poked around and couldn't find the answer, so please excuse if this is common knowledge. Is SDHC (secure digitial high capacity (AKA big honking SD cards)) supposed do be handled in the 2.6.23+ kernels?

is that also true for c860. The reason I'm asking is that I'm not sure if the hardware supports it. is there also a size limit like 4GB, 8GB etc.

If your OS has a direct access to the SD (i. e. your SD slot is seen as mmcblk* and not sd*), then new kernels will support SDHC there. There is one remaining issue: SDHC defines higher transfer rates. I think that all SDHC cards work at standard SD rate as well. |

For example: I tested four A-Data cards (MMC 1GB, SD/USB Duo 2GB, SDHC 16GB, myUSB stick). All of them read data correctly, but sometimes don't write data on Zaurus but write operation returns OK (note that at least for two of them, the failure was reproducible on desktop Linux machine). Card from other manufacturers don't exhibit this bahavior. |
