My initial assumption was that you are familiar with the specific type of device you are asking about. Then, I remembered I was tempted by the SD form-factor as well. I think you are asking for trouble because SD cards support "Content Protection for Recordable Media (CPRM)." One of the "features" is "'key revocation' technology built into each card." http://www.sdcard.org/developers/tech/ I also read that speed is hampered by the interface design because they wanted something they could patent, rather than just re-implementing SPI (Serial Peripheral Interface). The SD card Association has a what would have been a promising floppy replacement without those two deliberate design flaws. If you are aware of that and sill want a SDHC reader, I don't have any reason to stop you :) Regards, James Phillips > So my question is: does anybody know _for sure_ of a > hard-disk netbook > with a media reader that uses the sdhci interface > and is supported by FBSD 7.2 (supported = wireless,X,USB). <SNIP!> __________________________________________________________________ Yahoo!
