They're not SD cards, they're SD
HC cards.. and every SDHC card so far has failed to work with our Axims, because they're SD 2.0 standard, and SD 2.0 isn't backwards compatible to SD 1.1. There are cameras out there which have SD 2.0-capable equipment and just need a firmware update to use them, but our Axims so far have been unable to read them, and the likelihood of an upgrade to fix this is slender to none, because Dell's support is spotty and because they went cheap on a lot of the parts (look at the LCD) to keep costs down... which means that SD 2.0 is unlikely to have been part of the spec when they put these together.
To quote Sandisk, "Because SDHC cards are recognized by new SDHC host devices differently then standard SD cards, it
is not backwards compatible with legacy SD format host devices. Standard SD cards
are forward compatible with new SDHC host devices." There are apparently hardware changes in the cards themselves to allow them to have speed classes which specify a sustained transfer rate to the card, especially as the SD Card Association's whitepaper specifies that SD/SDHC hybrid cards have a hardware switch in them to allow backwards compatibility of the card itself to older SD devices, with separate memory areas for the SD and SDHC sections.
So... 'no' is the answer, which you'd probably have gotten if you'd done an SDHC search in the search part of the forum. This thread's mostly meant to say 'used this card, works great' or 'used a 4GB SDHC card, no go'. Actually, if you'd even read the FIRST post in this thread, you'd have seen the following:
