Hi Guys, Hopefully you can help me out with this, ive searched on Google and struggled to find anything that helps. I have a Sony Vaio VGN-Z31MN with Windows 7, it has a built in SD Card Reader but it doesnt seem to be working. This worked fine on Vista and XP but not on Windows 7. It doesnt show up in My Computer and nothing happens when i put the card in. I checked on Device Manager and there is nothing with an exclamation mark at the side of it. Under SD Host Adapters it says 'SDA Standard Compliant SD Host Controller'. I know the card is working fine as i have tried it in other PCs/laptops. Any help would be great!
