Windows 7: SD card reader does not work

Windows 7 issue or not?

Well, after lots of research and sorting out ridiculous suggestions from actual informed possible solutions, I have found that this issue is quite widespread and by some accounts only presented after certain W7 updates. In other words, working readers stopped working after the updates.

The machines that originally had my readers working were running XP Pro and Vista Home. I'm going to disconnect my 2 HDDs with content and install XP on the blank disk. If the reader works, it is a W7 issue.

One other interesting thing is that some people report this problem to be only affecting the SD Card slot of their multi-card reader. I will have to go and dig out a Sony Memory Stick to see if mine does the same.

I have turned the "Hide empty drives" off in Folder Options / View tab. All this does is show that the disk slots are there but don't detect inserted media. Contrary to some suggestions, this does not fix anything.

Just for interest here is a screen shot from Windows 7 Device Manager showing that the reader is recognised and apparently "working properly". This is what it looks like with the Generic 2006 Windows drivers. It changes when Driver Booster 4 detects the reader as a Realtek 2.0 Reader.

No different in Windows 10

Well I couldn't get XP to install on this computer so I did a Windows 10 Home Single Language install instead.

Windows 10 is performing exactly the same as 7. Generic drivers from Microsoft 2006 show as Mass USB storage device, lists drive letters in Portable devices and shows each slot by type as a drive in Disk Drives. Drive icons can be seen in File Explorer, or not, by changing Hide empty drives setting and Disk Management shows slots as drives with No Media.

Driver analysis software detects the Card Reader as Realtek and once these drivers are updated it behaves as described in thread above. ie Portable Drives gone from Device Manager and missing from Disk Drives. They can be shown by in-hiding them.

Next step is to try a Memory Stick in the appropriate slot to see if the reader is only dropping the SD slot.

Then put the whole Card Reader back in it's old machine and see what it does there.

No comments or suggestions from any Computer / Windows 7 boffins yet?

Sd Card Only

It is, or appears to be, the SD Card slot only that doesn't work. I put my Memory Sticks in and they read just fine.

Or perhaps it is just that the SD Card reader on this device is not up to handling even 8GB. The Memory sticks are quite oldish and relatively low capacity. I also just noticed in looking at my Micro SD Cards, that they are SDHC, so perhaps the reader simply can't handle that format. I hadn't even considered that the reader might just be too old to handle more recent card chips.

I'm surprised by this as it is a USB 2.0 device and so is the el'cheapo external one that does read the Micro SDHC. I've wasted enough time on it now so it's best to give up.

Next step is to junk it and go get a new one that will read current card chip standards.

Does an SD Card Reader need the Realtek 2.0 Card Reader Driver?
Hello, I have a question about SD Card Readers. I have one where you insert the SD Card, and plug in a USB cable to connect it to the computer. Does the SD Card use a USB Root Hub to connect, or does it use the Realtek 2.0 Card Reader? My real question is, if I had accidentally uninstalled my...
