I have a SONY VAIO VGN-17C and I cannot read memory cards. I also lost the installation disk. How to get on the web something to fix up this mess?
Sony VAIO Laptops
Sony manufactures a dozens of VGN laptops for consumers around the globe. I was unable to find specifics for the VGN-17C though I did stumble across a VGN-TX17C model. Nevertheless, my advice is the same no matter what the model number happens to be. It sounds as though the built-in memory card reader is not working. The first thing to try is to see what the Device Manager has to say about it. The second thing to try is to go to Sony’s Web site and find updated device drivers for your model.
Device Manager
The Device Manager is a useful tool when your computer’s hardware malfunctions. Not only can you view error messages related to your devices, you can update the device drivers which often solves the problem. Right-click My Computer and choose Properties. If you have Windows XP, click the Hardware tab followed by Device Manager. If you have Windows Vista, click the Device Manager link.
Once inside the Device Manager window, find the Memory Technology Driver category and expand it by clicking the plus sign next to it. I’m betting that you will see a yellow warning icon by the Integrated Flash Media Controller. Double click the device and view the error message. Most likely, the driver for the device is missing or corrupt. If so, click the Driver tab followed by Update Driver. Allow Windows to search for the device driver automatically. If Windows finds an updated driver, it will install it. You must reboot your computer for the update to complete.
Another trick is to uninstall the memory card reader while in Device Manager (right click the device and choose Uninstall) and then reboot the computer. Windows will detect the new hardware when it reboots and should automatically load the correct driver for it. Again, a reboot may be necessary.
Sony Support
Sony offers online support for its products. Choose the correct Sony support site for your country and then find the Drivers and Software section. Enter your model number into the form field. Double-check your model number by looking at the sticker on the bottom of your laptop to ensure that no letters are missed. If your model appears, you’ll then see a list of downloads for your computer. Make sure to first select the operating system so that the software listed is for your specific operating system. Look for memory card reader/writer, memory card, or memory stick in the category list. Download and install any updates.
