Hello!
I have this problem since a week now :
I've tried reusing 3 different SD cards from 3 different brands, yet putting them into my SD Card reader puts me in read only mode (and no, the physical lock isn't activated). My computer is still on the Windows 8.1 it was pre installed with, no hardware modifications. This is what I get in DiskPart :
It's the same for all 3 cards, even after clearing the readonly attributes. chkdsk gives me no errors on any of the cards.
I tried updating the drivers from the official HP Support page and from Realtek's website. Did nothing, still stuck.
I tried using a friend's laptop to see where was the problem : the cards were all working correctly, and not stuck in readonly. I then checked the hardware side of my card reader and it do was solidly attached to the motherboard.
I guess it's a driver problem then.
Any other drivers I could try?
Solved! Go to Solution.

For now, try these steps:
Please perform a hard reset on the computer first by following instructions from this link: https://hp.care/2nwQ054
- Then update the bios and card reader drivers if available from this link: https://hp.care/2syreDe and follow the on-screen instructions.
- Shut down the computer. Then the moment you turn it back on, keep tapping the ESC key gently several times.
- IT takes you to the startup menu.
- Here press the F10 key to go to the bios.
- Then push the F9 key to load setup defaults
- Later press F10 to save changed and exit.
- Once you are booted back to windows please try the card reader with multiple memory cards and check if they work correctly.
- Also, check if these cards work correctly on a different device like your smartphone or iPad or another computer.
If they work correctly then perform all the prescribed steps from this link: https://hp.care/2DAWTXX (HP Notebook PCs - Using and Troubleshooting Memory Card Readers (Windows 8)

Good Day. A warm welcome to the HP community.
I reviewed the case regarding issues with the computer crashes randomly. I will be delighted to assist you here.
Superb description, brilliant troubleshooting and terrific observations made before posting. Kudos to you for that. 😉
Please try these steps:
To remove the write protection, simply open your Start menu, and click on Run. Type in regedit and press Enter. This will open the registry editor.
The next step is to navigate to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
Double-click the WriteProtect key located in the right side pane and set the value to 0. Go to the Data Value box and press OK.
This should do the trick for you.Please perform all these steps patiently as it is critical to resolving the issue.
The trick is to remain patient, Going by your technical expertise and competence I am sure you will be able to perform these steps without breaking a sweat. 🙂
Hope this helps. Let me know how it goes. 😉

Hello there @Barachiel !
Thanks a lot for taking a look at my case.
I forgot to mention it, but I already tried a similar trick. I did it again just to be sure, and still nothing.
Though something very weird is there in my registry ; instead of "WriteProtect" key I had a "write Protection" key. Weird capitalizations, and I don't have anything similar in other Windows 8.1 VMs (though the W8.1 I have in my VMs are not OEM HP versions, I guess here's the difference).
I both changed them to 0 and restarted Windows, yet no changes. Am I wrong on key type? I used D-WORD 32 bit value, maybe I should try with something else?
Also, same results for DiskPart and checkdisk. After and before cleaning readonly attributes again.
I'm going to try to create that key for each ControlSet, even though I don't think it'll do much more differences. Editing this post after I see what happens.
EDIT : Creating the key on the second ControlSet (HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002) did nothing, still the same results from DiskPart and checkdisk, Write Protection is still enabled (the CurrentControlSet was modifying ControlSet001). Also, from what i've found on google, WriteProtect do is a DWORD 32 bit key, so I guess I shouldn't try anything else, correct me if i'm wrong.
Again, thanks for taking a look at my problem.

Hello there Barachiel!
Seems like the BIOS was the problem, after a configuration reset the card reader stopped working, then it suddenly worked again after a reboot and driver uninstall/reinstall. (I tried these first instead of hard reseting Windows first since I had no time and had to use the machine for work later)
Thanks a lot for the help!
