I've checked the prior threads, and have not found the answer. In this respect, I am specifying specifics. 1. I presently have a Hp P6370t, Windows 7. On the PC, the card reader states SD/MINI/MMCRS/PLUS/MOBILE. 2. A recent camera purchase allows the use of SDHC. Will the above computer read SDHC? Is this contingent upon the operating system, USB 1, or 2, or the reader itself? 3. I plan on using a class 10 memory card, which displays iiself as UHS-1. Would there be any significance as to class 4, 6, or 10, in terms of 'reading' the memory card? 4. Any and all replies welcome. Thank you very much.
