Just get a card reader that is compatible with both formats, such as this one:

> SDHC係咪一般card reader讀唔到
SDHC is NOT backwards compatible with standard SD card slots. You'll need an SDHC-compatible card reader to access the card
> 我部相機讀唔到SDHC
Depending on camera model, some older camera models can be made SDHC-compatible via camera firmware update. You'll have to check if your camera model can be updated to be SDHC-compatible. Visit the manufacturer's website for more info.
> 我再把sdhc放落card reader,,,, 但係都唔得~~係咩既問題
Your have an older card reader that is not SDHC-compatible. You'll need to get a new one.
