I recently upgraded one of my laptops from Vista to Windows 7 and everything went smoothly except when I tried to insert an SD card in the memory slot and found out that it was not working. When I checked Device Manager in Control Panel, I saw that there was a “Mass Storage” device which had the exclamation sign, meaning it was not working properly. It is this that was causing the problem and I tried to update the driver through Control Panel but Windows was unable to do it.
I also tried one of the recovery CDs that I got from Toshiba but that didn’t work as well. So I started looking on the web for a mass storage device for my Toshiba A100 027 laptop but couldn’t find it. It’s not even listed on the Toshiba website and they usually have quite a lot of drivers for you to download just in case you need them. Anyway, I was lucky enough to stumble upon a forum which had a link to a driver which would solve the problem. Here’s the direct link to the driver for the SD card reader:
I am always skeptic of downloading .exe file (executables) as they may contain viruses/trojans but the above link is safe and works well on my laptop. After installing it, I was able to get the SD memory card reader to work properly again.
