SDHC not read in Windows 7 via Bootcamp

I have a Sandisk Extreme Pro 45MB/s 8GB SD card - it works fine in OS X but in Windows the card fails to be read (Windows doesn't recognise it at all). The driver for the SD Card installed from Bootcamp is a BroadCom one, if I remove that and use a generic one, Windows recognises the card being inserted (by playing a little sound) but device driver shows the SD drive cannot start. Other cards work fine in Windows so I suspect this is a problem with the Broadcom driver (64bit by the way), and just to re-iterate the card reader is fine in OS X so it can't be a hardware fault.

I know I can just use OS X to read the cards, but this can be inconvenient when I am working in Windows 7.

Has anyone come across this issue? Is there an updated driver I can get outside of BootCamp.

Cheers

Ian

Solved. I installed Broadcom card reader driver from:

http://drivers.mydrivers.com/drivers/443-177573-Broadcom-15.0.6.2-For-WinXP-32-W inXP-64-/

If you don't know Chinese, you can also download it from http://www.station-drivers.com/page/broadcom.htm

Initially the write speed was only about 10MB/s under Win7 (It's about 20MB/s under Mac OS). I then upgraded all my drivers with Driver Genius (http://www.drivergenius.com/), again a Chinese software. Now the write speed is 20MB/s. I guess it has something to do with new chipset driver.

Gaogan,

Thaks for sharing your experience, but it didn't help me. I've downloaded and installed the suggested driver, but the memory card doesn't even show up.

But I can use the memory card by connecting my Nikon D7000 via cable to the computer. So it is not that I'm lost. It is just irritating. So again - thank you for your effort.

gaogan's solution worked for me. my bootcamp would not recognize a 64gig sandisk micro sd card at all but would recognize other 32 / 16 / 8 gig cards. after installing the Broadcom Card Reader drivers he listed above, the bootcamp windows 7 partition read the 64 gig card fine! awesome!

I followed gaogan's solution but downloaded the driver at a different location.

1. On Windows 7, go to Device Manager, find SD Host Adapters, right click on the Broadcom one and Uninstall Driver (also Delete driver).

2. Download and install this driver: Broadcom card reader driver version 15.0.6.2

http://drivers.softpedia.com/get/CARD-READERS/Broadcom/Acer-Aspire-E1-571-Broadc om-Card-Reader-Driver-15062-for-Windows-7.shtml

It worked like a charm! Read/write speed is super fast! No need to install drivergenius.

Thanks! Solved the problem (MacBook Air 13)

The driver linked to by dipix worked for me, thanks!

I ran the setup.exe from the "x64" folder within the zip file and then restarted the computer and the card showed up. Note that the device in Device Manager still reads "APPLE SD Card Reader USB Device" as it did before I installed this driver.

What if there is no SD host adapter to begin with?

Thank you. You are so helpful!

For several hours I struggled to make my SD card work with bootcamp. In the Device manager I didn't have "SD host adapter" so I directly installed the driver from your link and it worked perfectly!
