SW-6713 12-in-1 Express Card Adapter/Reader not compatible w/ certain cards

[Jordan]

One customer emailed today stating that he had ordered the 12-in-1 Expresscard card reader. He was using it on his MacBookPro with a 2GB SanDisk III SD card. The card adapter worked fine with all his regular SD cards. But for some reason the Extreme III just wouldnt work. Any other card readers out there with the same problem?

We've seen a few of the same problem.  It's because a lot of the 2 GB and higher cards use the new SDHC version of the SD format.  This uses a different addressing method.  From what i've read, it uses block addressing instead of bit addressing.  So if the adapter only recognizes the older style addressing then it wouldn't work.  This is actually a pretty wide spread problem with older card readers and even SD devices.

You'll want to check to see if your devices support SDHC before assuming they do.

Standard (non High Capacity) SD cards can go up to 4 gigs, so you will also want to check when you buy a card that it will be compatible with your devices.  Most of the *more affordable* SD cards under 4 gigs will be standard.  If you go larger than 4, it will be HC.
