Adding SDHC support for Windows — with your old SD card reader

sdhc-logo Get SDHC work in your old card reader.

SDHC (Secure Digital High Capacity, SD 2.0), allows capacities in excess of 2 GB and is designed to meet the fast-growing demand of the high-volume storage market. It uses the same form factor as SD, but the SD 2.0 standard in SDHC uses a different memory addressing method (sector addressing vs. byte addressing)  and were supposed to only work in SDHC compatible devices while standard SD cards work in both SD and SDHC devices. So in order to get SDHC work with your computer, you either have to get a SDHC supported card reader or use the card in the SDHC compatible device and connect the device to your computer to read/write from it.



In fact, this is not exactly the case, I’ve seen more and more handheld devices adding SDHC support when upgrading to Windows Moblie 6 or applying "SDHC patch"(as in  Palms). So this makes me wondering, does SDHC support is really a hardware thing, or software only?

And after some digging, I found this:

http://support.microsoft.com/kb/923293

which adds support for SD High Capacity memory cards in Windows XP.  A newer version of the patch can be found here:

http://support.microsoft.com/kb/934428

it adds support for cards>4GB as well.  so KB934428 is all we need.

Again, Microsoft is reluctant to give out the hotfix, here is the trick to get it. The patch works instantly on my old Lexar SD Reader(bought 2005) and a 4GB SDHC card. YMMV though, but its definitely worth a try.

Or you may grab it from us

For Vista users, the patch is KB936825, for x86 or x64 system.

    Thank you so much for this link. Thanks to you, we got 2 of our 3 laptops reading SDHC cards. The only one left is a HP NX9600 with TI PCIxx21 controller. Nothing sems to work. Any ideas? The PC is a P4 3.6GHZ with HT. 1 Gig ram.

    Thanks so much!

    […] takes forever to respond, you actually have to wait for a live person to respond, so I found the SDHC card hotfix online and that was that! Now my computer recognizes my 4GB SD card no problem. […]

    It’s at Version 3 now on the MS site. I’m not sure how different this is to the v2 directly-downloadable from this site, but I’ll try v3.

    I have downloaded the file and have attempted to run it, but I keep getting that the patch “is not a valid Win32 application.” What am I missing here?

    Thank you so much for posting WindowsXP-KB934428-v2-x86-ENU.zip (512kb) on your website. The Microsoft site has WindowsXP-KB934428-v3-x86-ENU.exe (96kb) on their website, and the file did not install. Yours installed, and now my laptop (Dell Inspiron 6000) reads the card perfectly.

    I have the same as Bob Marshall…the fix reports that the SP3 release on my machine is newer than the fix and the fix refuses to apply itself. Still can’t see a 4GB SDHC card.

    I’ve got the same thing going as Kevin and Bob - running the hotfix replies that my latest service pack is newer than the fix and therefore will not run it - but my system still will not recognize my 8gb SDHC card. Thanks for any help anyone can give. Joel

    Dang it! The Vista x64 patch installer wont run on Server 2008 x64. Anyone running Server 08 manage to get this thing installed?

    Sane problem as Joel. Because of SP3, the patch can’t be installed. Anyone with a solution for the patch in SP3?

    When I take a look at the files mentioned in the patch I see:
    sdbus.sys version:6.0.4069.5512

    So this is newer than the patch.

    hey!!! good lookin out for the public!!! works great on my dell inspiron 6000 xpsp2! also works on inspiron 1520..same OS.
    and you even had a link outside of MS so that theres no validation…! hahahahaaaaaa

    seriously though…thanks alot.

    used 8gig micro sdhc. put that in the sd to micro sd adaptor with the new hotfix and bingo~

    regards

    p.s. i never really post on forums but I had to show my gratitude. keep up the good work

    Thanks for the info. My Father bought a Sandisk Micro 4gb HC card for his HTC 8525 and it did not see it. Neither my generic clone (winXPpro) or his Compaq (WinXPhome) would see the 4gb HC micro card.

    I will try out the hot fix and see if I can get it up to snuff. I had read on xda-developers a number of WM6.1 kitchen roms for the now outdated 8125 and similar 8525 successfull useage of 4-8Gb SDHC storage media.

    I suppose they (manufacturers) make the SDHC information scarce to increase the aftermarket hardware sales. Unethical? A point for debate. Damned rude? Without a doubt!

    Thanks for putting up a candle in the window.

    For the SP3 people, the KB934428 hotfix was released prior to (and is included in) your service pack.
    (http://support.microsoft.com/kb/946480)

    If you still aren’t seeing SDHC, I’m afraid you may be limited by your card reader’s hardware afterall. You may luck out & find a firmware upgrade, but few manufacturers seemed to have released them. ($$?)

    I have sp3 with the same problem .I couldn’t find a fix or a driver any where to solve this problem.But I found a trick to make it work . Install the driver for vista that your laptop manufacturer provides. make sure you install the driver that supports 4gb and more ,as for example HP have 2 drivers for vista . before the installation make sure you completely uninstall the xp driver in add/remove software and in device manager.SDHC cards with 4 gb and more will work fine. The only problem your old cards 2 gb and less won’t work .but ofcourse you can always go back to your old driver…so as you see it’s definately a driver issue . and microsoft are aware of that but they want to push people to but newer products…hope this helps,,

    I have 2 toshiba laptops a tercra A7 and Tecra A9 both have the exact same flash media device. Same hardware id’s and EVERYTHING matches in device manager. My A7 will not read my 8gb or 16gb cards but my A9 will just fine so there must be a firmware difference anyone know if there is a way to update the firmware on it?

    I used this fix when I had SP2 and when SP3 was installed it still worked. However, I recently upgraded the laptop’s HDD and reloaded WinXP and now I can’t get the internal card reader to recognize anything bigger than a 2gig card.

    I’m really surprised the people over at HP (I have an HP ZV6000) haven’t put out an update for this since it seems to be a common problem over there on their support forums.

    BRILLIANT! JUST RUN THIS ON AN ACER 7520 WHICH I HAVE PREVIOUSLY UNINSTALLED VISTA AND PUT XP ON. SO I CAN NOW READ AN 8GB SDHC CARD IN AN ‘SD’ CARD READER.

    NICE

    My dell inspiron would only read up to 2gb cards and I haven’t installed and special fix,but it now reads sdhc so I am assuming sp3 came with a patch for it to work.

    What we really need is a tool or method to determine if a card reader supports high-capacity SD. Does anyone know if something like PC Wizard or SiSoft Sandra tells you is your reader is up to snuff?

    Thanks
