SD card not detected in HP dc5750m

The multi card reader on my HP DC5750M can not read SD cards larger than 1GB. I checked the web site for an update I could not find any. Do you know how I can solve this problem please?

Here it is, simple steps, 3 in total, less than 5 minutes to fix!

1. Download this file which is the hotfix from Microsoft and which you MUST install: http://support.microsoft.com/kb/923293

 

Do not reboot the computer at this time. You have two more steps.

 

2. Download this file which is the latest driver of WinXP/Vista:
http://tinyurl.com/2ucfxe - (version 2.0.0.7 for ALL vendors, not just HP). Install it and complete the remaining step before rebooting.

 

3. FINAL AND MOST IMPORTANT STEP! You simply need to edit the registry in order to have Windows properly recognize the card reader:

~ Run regedit.
~ Key you want to edit is located in:
~ HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\tifm21\Parameters
~ Original Key Value: SDParam = 16 (Decimal)
~ New Key Value: SDParam = 1
~ Reboot for new setting to take effect.

That's it and you're done. When you restart the computer and put your multimedia card in, you will see something you've never seen before... the little light on the side of your computer reading the card you've inserted!

Re: SD card not detected in HP dc5750m

Thank you for the respond. I have installed the Hotfix and the HP driver, when I went to my registry I could not see way tifm21 folder, I did searched for SDParam as well, nothing came up. I should say that this is a Multicard reader bay on my DC5750M and it working for cards less than 1GB, So I am not sure why there should not be any parameter in the registry.

If you have SP3 it will not work. That download is installed when you install SP3. My suggestion would be to buy a new usb card reader that will accept media larger than 1GIG.

 

Have you chatted with HP about this issue?

No I have not talked to them yet, I thought this is a simple issue and some one here might be able to help. Do you think the HP guys read the forum?
