I tried using my 2 GB [microSD card](http://en.wikipedia.org/wiki/Secure_Digital#Physical_size) using the built-in card reader. On clicking the drive I get:

> 
> Please insert a disk into SD/MMC
>

The card works fine on other computers, as does the microSD-to-SD attachment.

I have tried the following to fix:

* Updated Windows Vista and installed SP1.
* Updated the TI drivers for FlashDrive.
* Checked the VAIO site for updates (none required).
* Added a new entry as advised [here](http://www.microsoft.com/communities/newsgrou%20ps/en-us/default.aspx?dg=microsoft.public.win%20dows.vista.hardware_devices&tid=49457bd9-%203f65-4963-bbee-b3f20faeccd5&cat=&lang%20=&cr=&sloc=&p=1):

```
HKLM\SYSTEM\ControlS* et001\Services\tifm21\Parameters/SDParam=1

```

I have restarted the PC multiple times. As soon as I put the card in, the SD/MMC device icon blips, so it seems the hardware is at least detecting something. The card reader was working fine a few days back.

I guess a Windows update has broken something. How do I proceed?

My laptop is a Sony VAIO VGN-N365E.
