Computer cannot detect SD Memory card on USB Solved/Closed

Question

Hello,

Both my computers cannot detect a 4  brand GB mermory card inserted in a USB slot through a card reader. The first one I had tried was an HP and I exchanged it for a Kingston.\, but neither works. SDtrangely,  2 GB SD cards  work perfectly, though. The store I bought it from tried it on their computer and it works
.Neither of  my home computers are  latest generation but   they less than 5 years old  and  work perfectly! 
I have XP and I noticed when the card is plugged in ,the computer freezes :"  My computer " gives a warning  that it it is not responding and my browser ( Avant) hangs. 

Any clues ?

Thank you

Hello everyone,

I also have the same problem with my 4GB SDHC card. This is what I found: 


SD and SDHC compliance

If your computer's internal card reader works with 2GB (or lower) SD cards but fails to read a 4GB (or higher) SDHC card, then the computer's internal reader is not SDHC compliant. 

This same logic also applies to digital cameras, if the digital camera reads 2GB (or lower) SD cards but fails to read a 4GB (or higher) SDHC card, then the digital camera is not SDHC compliant. 


SD and SDHC specifications

The initial SD card specification defined the interface for cards only up to 2GB capacity. The subsequent SDHC specification was developed to provide increased capacity of 4GB – 32GB cards. Computers and other products purchased before 2008 may not be SDHC compatible. Computers and other products purchased before 2007 are not SDHC compatible. 


Verifying the card reader slot

If the card reader slot on your computer does not have the SDHC logo, it is most likely not SDHC compatible and will only read cards up to 2GB capacity. 


Other options you can use to read files on your SDHC card 
If your computer's card reader is not SDHC compatible, you have 3 options available: 

1. You can connect your camera (or other device) that works with SDHC to your computer using a USB cable that came with the camera. You should be able to transfer files to the computer this way. 
2. You can contact you computer manufacturer to see if they have a free firmware update for your model that will make it SDHC compatible 
3. You can buy inexpensive SanDisk SDHC card readers that will connect to your computer's USB port."

umm yeah so I might have a solution. at least it worked for me, I took my 2g micro sd and put it in my adapter and placed it in a camera and formatted it that way. [since nothing else was working] then when I checked my computer the said it was canon_[something] but this gave me hope so I tried putting music in it and then put it in my phone and tried to see if it worked. unfortunately nothing picked up on my phone, but I figured that if you place a picture or something onto the card and then plugged it into the computer it changes things however and would have the pix/flix/music folders, and it did and now my mirco sd card is working again :) hope this helps out someone

here is a suggestion that I have found that works for *SOME* people.  give it a whirl and see if it works for you.....

1. Uninstall SP3, and reboot into SP2. 
2. Copy the following files from c:\windows\system32\drivers to somewhere safe: sdbus.sys, sffdisk.sys, sffp_sd.sys. I put them on my desktop. They should all be version 6.0.4061.1 
3. Install SP3, and reboot. 
4. Shutdown, and restart using F8 to go into Safe Mode. 
5. Log in as Administrator (or another account with admin rights)
6. In C:\windows\system32\drivers rename each of sdbus.sys, sffdisk.sys and sffp_sd.sys.to have a .old extension. 
7. Copy the files you saved in step 2 to c:\windows\systems32\drivers
8. Shutdown and restart normally.

This solution might seem rather rudimentary but it worked for me..  When I insert the SD card in in my Toshiba it makes the recognition sound every time and flashed the LED light, but when I went to My Computer to see, it was not there anymore. Its stopped being recognized. I tried everything from thorough cleaning, slow insertion, checking drivers, external help and so on... so, just about to give up, I cut a piece of thin cardboard and placed it on the upper side of the card (the side that does not have the metallic contacts), then I slid it slowly.. and voila.. it worked. The tiny internal contacts, pins or whatever, must have lost their flexibility by now.. Do it with extra care so you don't push those internal pins too much. Good luck
