I need to know if a SDHC card reader will read regular non HC SD cards or vise versa.
Yes, but this reverse is not necessarily true, in that your gaming device may not handle an SDHC card, as they are formatted completely differently from SD cards.
yes and no some readers can not read above 2 GIGs some SDHC are 8 -16 or higher and need special readersbut if you have a high reader then it will read standard sd cards
SDHC card readers only read SD and SDHC cards. These 2 cards are the same size, and have the same pin count. THe HC stands for High Density (referring to the memory type found inside the plastic casing). It can also read MiniSD cards. MiniSD cards typically ship with a SDHC adapter which changes the size of the card so it fits into a card reader. to the below answer: Actually, that used to be the case with card readers made in pre 2007. Unless you are dealing with a card reader that is more than 3 years old, you will not have the SD and SDHC compatibility problem. All card readers built into the PC nowadays are SDHC card readers and will take both.
