Built-in SD card reader won't auto-detect an SD card anymore (WIN 7 Pro)


  • I have a Fujitsu T series (actually the T4410) convertable laptop running WIN 7 Pro (32 bit).  In the past, when I stuck an SD card into the unit's built-in SD card reader, WIN 7 would automatically see the card and I could drag-drop or whatever I need to from there.  The issue exists with 1 GB and 4 GB SD cards so I don't think it is a card capacity issue.

    About 4 months ago, the SD card reader stopped auto-detecting an SD card when one was inserted into the built-in SD card reader.  I think it may have been a Windows 7 update that possibly that messed things up.  I've called Fujitsu and they have no fix other than to re-install WIN7.  What I've been doing in the mean time, every time I need to use the SD card reader, I open Device Manager and rescan devices and WIN7 then finds the SD card reader and the card inserted.

    Curious to if anyone has heard of this problem (related to a WIN 7 update?) and if you know if a fix?  The fact that after WIN7's Device Manager finds the SD card reader after I rescan each time, the reader is functional but the issue appears to be related to WIN7.  Thanks.

  • You need to ensure the current driver & software for the card reader from Fujitsu are installed.  Those drivers are not supplied by Microsoft.

  • Device Manager says that my driver is up to date for my SD card reader.  What else can I try?

  • Also try to update BIOS and chipset to the latest version.


    And you’d better contact PC manufacturer to check if the SD card reader has broken.

  • I actually got it to work now by reverting to an old driver.  The current driver doesn't auto-detect SD cards but the old one does.  Weird.
