I had problems with a Sandisk 8gb microSD card purchased from Amazon. I tried two different mini-to-micro adapters without success. A friend suggested I get the three-piece Sandisk set (2-gb microSD card, mini-to-micro adapter and a SD-to-micro adapter available locally). Its mini-to-micro adapter worked.

The attached image shows the set with the mini-to-micro adapter in the middle. Note, two of the runs on the connector are longer than the rest. My Patriot 8-gb miniSD card's connector is made in the same way. I don't know if this is proof why many adapters don't work.

BTW, I formatted and loaded files on the Sandisk card using a card reader. I have not noted any problems with it.
