MicroSDHC is GREAT - Adapter is JUNK!,
This review is from: Transcend 4 GB Class 6 microSDHC Flash Memory Card TS4GUSDHC6 (Personal Computers)
My overall view of the Transcend MicroSD card is that the product itself is good; however, the adapter that comes with it is not HC compatible. I have contacted Transcend directly about this shortfall and they are replacing the adapters as we speak. I do not blame the vendor that sold the card as the package was sealed and it was not a pirated version of the product. There are many different products available through the Amazon website that are also not HC compatible but sold with high capacity markings. If I were to purchase more cards from Amazon.com I would ensure the vendor tested the functionality with HC cards before I ordered them or allowed them to be shipped to me. I suggest dealing direct wth the manufacturer for these VERY FAST MicroSD Cards as they are now available directly on their website.

The adapters are not "HC" or "Non-HC". There are no electronics in the adapters so there is no such thing as an adapter being incompatible with HC. The adapter only has contact leads that allow the smaller form factor MicroSD to be plugged into a standard SD slot.

It may be true that at the data rates supported by current SD cards the adapter doesn't affect the data transmission, but that does not mean that there are no "electronics" involved. For each pin on the SD card there is a wire that must connect the micro pin to the standard adapter pin. Data movement creates moving magnetic fields in the wires, causing them to act like inductors. Depending on the design, it is possible that data bits could have a phase shift, causing data loss. I'm not saying this happens in the adapters, just that there is more to this than discrete components and HC vs Non-HC is possible.
