You need the recovery disk, one has Windows and the other has the device drivers.
This WEB site can supply the recovery disks.

There is a specific set of driver you have to install for your computer, Vaio laptops use the ACPI fucnction to control hardware access like volume / brightness control etc
You need the ACPI driver installed for Fn key to work
Install Sony Notebook Control Driver for windows vista
Install Sony Utils.dll
Install Sony Shared Library
same for your sd card reader just reinstall the drivers

sony only supports the factory shipped os drivers you will have to find the drivers for 7 elsewhere or reinstall your factory os

Download all the windows 7 updates and install then restart. Windows update are not only updating your windows 7 but also updating your hardware driver. After updating try again your sd card or if still the same can not read try some memory card reader then test it to your laptop. Have a nice day.

Most likely missing a driver for SD/MC card reader
The problem is that Sony doesnt offer drivers for 64-bit windows so the other 32-bit drivers will not be compatible.
You have the options to install the windows versions supported by sony from esupport.sony.com (Vista or XP)
Or try installing windows 7 32-bit and installing the missing drivers from esupport (Vista section) as usually they are compatible.
If the driver is still missing you will need to update the driver from device manager (previously installed from esupport) and then select to browse or select a location, which will be %temp% or what is the same the temp folder for your account C\users\your_user_name\appdata\temp. This folder is usually hidden but it will work if you just type %temp%

Hi,

I checked the information and found that the computer does not qualify for a Windows 7 Upgrade from Sony. But as we have tried, Windows Vista drivers work with Windows 7 as the core for both the OS is same. I suggest that you download install Memory Card driver for Windows Vista from the below link to resolve the issue with the SD Card. I have also provided the link to download Sony Shared Library which you should install first.

Thanks!!!!

I'd suggest ring back Sony support and tell them that your OS is Windows 7 - not Vista. Therefore, you need the upgraded VGA driver because the Vista driver is incompatible with Windows 7. Hope it all goes well. If my suggestion works for you, please do rate me. Thanks
