Hi all I'm letting you know that there doesn't seem to be any way to tell a genuine Sandisk 32Gb MicroSD card. I say this because I've been looking to upgrade my 16Gb MSDHC card to a 32Gb and ran into the picture above, on Amazon, which states that there will be a serial number on a genuine card, just below the 32Gb legend on the card. Yet scroll up to the device they're selling and it's as bald a newborn baby's tush. NO SERIAL NUMBER!! There are so many scare stories on the Net about people losing data that although I've sworn by Sandisk Memory for years now, I've reached the point where I might look elsewhere. Sandisk memory has always been a reliable, fair priced product that has NEVER let me down. But the counterfeiters are doing them a serious injustice. If you unwittingly buy a fake Sandisk MSDHC, kick up a stink with the seller and let them know you know it's fake and you will be adding their name to the 'I'll never buy from you again Hitlist '. Perhaps they'll start stocking the good old reliable devices Sandisk supply. I have no affiliation to Sandisk, just a bit peeved that I may have to pay top dollar for a device Sandisk could've supplied for a more reasonable price.
