Windows 7 - New Win7 installation - SD card not working

It looks like this is a fairly common issue, but I can't seem to figure out what the solution is, or if there is a solution.

Yesterday (10/25/09), I installed Win 7 Home Premium on my wife's Gateway MX8739 Notebook (Pentium Dual-Core, 1.6GHz, 1GB RAM). It has a built-in SD card reader, which always worked fine under Vista. Vista came pre-installed on the machine when we got it 18 months ago or so. Under the new Win 7 installation, the SD slot doesn't seem to be recognized. There's nothing wrong with the card itself--it works fine in her camera.

I tried the O2 Flash Memory Card Driver 3 that was mentioned in another thread with no affect. Has anyone had this problem and successfully fixed it?

Go to the gateway web-sit. Go t the driver download section. Enter your serial # off the sticker on your laptop. Tell it what version of windows you are running. It will then display all the drivers for your laptop. Find the driver for your card reader and download it to your desktop. After DL is finished click on the icon to begin instalation.

You should be fine after that.

I tried this and it didn't work. I put the card in and it won't show up under "My Computer".

Well...I just bought a Gateway laptop (model NV5207) with Windows 7 loaded on it. so far all it's good for is playing games. The first thing I wanted to do was set the clock to the right time. Tried to open the control panel. *nothing*. Tried to use the SD reader... *nothing*. I haven't tried the CD/DVD drive yet..but I'm afraid there will be nothing there either. If there isn't ..I'm taking this thing back to the store. (sorry..just had to rant)

I did go to the Gateway site already. It's fairly lame. They don't even have Windows 7 listed as a specific option for the OS. Of course, I know that Windows 7 is supposedly close enough to Vista that most of the drivers should work, but then why did the card reader stop working in the first place?

I'll re-download the media card reader drivers and give it a shot, but I'm not expecting much.

Tell us the vendor id and hardware version of your card reader.

Well, I have almost similar problem. When I insert sd into reader it asks me to format card. i have tried many different cards. Still dont know how to fix that problem. Smart card reader worked well with my first Vista install which installed in store. After format it doesn´t work.

I have Sony VAIO® VGN-CR120E/L
sd card is not working. on Xp/Vista it was working. is there a way to find updates?

Extremly annoying queries without any usefull information (who is interested in the laptop model??). I am out here, so long.

Here is what I was able to find

Texas Instruments PCIxx12 FlashMedia Reader

and also found http://download.sony.com/US/pc/TIDFMC-13492700-US.EXE but it is not compatible!
