I have the same problem,I did a scan using my anti virus(symantic) and then did a format of the disk. It accepted to format, then every things started working.

Not all cards have a write protect switch.

I had this issue and found that it was multiple cards all of which didn't have the switch, I quickly realized that the issue was my PC not the card since the cards did work in another PC.

Here's how I fixed it:
open Regedit and navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\StroageDevicePolicies
If there is a WriteProtect key (REG_DWORD) then
1 = Write Protect On
0 = Write Protect Off

Set to 0 and try (may have to reboot in some cases)

i wan to say thanks to you,becoz i'm using the notebook for model acer aspire 4720,what usb thing i also cant copy or send it,when i follow ur step,i slove the problem it.^_^thanks you very much

Thank you . I actually broke off the wee slidey protect bit and a corner of the card, but half in done it for me. I now have a lovely 4GB SanDisk to fill with junk again. I wonder if that`ll work with the wife.....have a good one,mate.

I had the same 'disk is write protected' problem with a Raven MP3 player (USB drive).

Here's how I fixed it (for XP):

1. Go to the disk properties page.
2. Select the 'Hardware' tab.
3. In the 'All disk drives' list, select the name of the external device.
4. Click the 'Properties' button.
5. Select the 'Policies' tab.
6. Under 'Write caching and Safe Removal', select 'Optimize for performance'.

Few days back I had faced this issue and I too was frustrated by the large number of solutions offered on the internet that do not work. However finally I came across a blog post that has some less technical solutions to this problem. The virus removal trick in this article finally solved my problem.

I wish I had seen this thread on tomshardware forum before. It would have saved a lot of effort. I think someone of us must summarize this thread for lesser technical people like me.

"There is a tiny piece located on the side of the SD card, sometimes it gets pushed back and that write protects it. Just push the tiny piece forward and it will remove the write protection. I figured it out on my own. Nothing to do with software, etc.

I have here an sd card and it has slide lock on it. Whatever slides i make it, it still have write-protection.

I am using windows vista on my laptop. My laptop has a built-in card reader. Theres nothing i can use on that part.

I had also tried ozzyjazz's steps but i cant see any "eject" button.

I also tried the REGEDIT system but i cant also find the "storagedevicepolicy" folder neither word.

Help Me!!!!!! Plzzzz!!!! I tired on this WRITE-PROTECTION problem!!

 

[Guest]

WHAT DO YOU MEAN BY STEP 4 I DONT GET IT?? PLEASE HELP I HAVE TO UNLOCK THE CARD!!

 

[Guest]

I have read dozens of useless remedies for this problem with SD card readers. I have found a solution. It is not pretty but it works.

1) In My Computer, right click on the drive letter of your SD card and
2) Eject it.
3) Then pull the card out and stick it back in.
4) Try to write to the card. If it works, GREAT! Proceed with your copying.
5) If it DIDN'T work, repeat steps 1 through 4.

I have found that I sometimes have to try the process SEVERAL (6-8) times before I can write to the card.

I have found several references on the web to things called WRITE_PROT that lead me to believe that there is a software toggle inside the chip. Here are some lines from one .PDF file I found:

CMD28 SET_WRITE_PROT Optional
CMD29 CLR_WRITE_PROT Optional
CMD30 SEND_WRITE_PROT Optional

Those CMDs (I assume CMD stands for "Command") are listed in several .PDFs that are too technical for me to fully comprehend. Although I do not have the technical experience to prove it, I believe that this bit or setting is somehow being toggled by some kind of glitch. All I know is that I have been able to repeat my success on getting back write capabilities to my 1GB PNY SD card.

i dont get step 4????

 

[Guest]

I don't have my SD card handly but doesn't it have a write protect switch on the side of them? I'm almost certain my ScanDisk has one. Sorry other then that I have no soultions .... I've never had that problem and I put everything on my SD and take it home.

Found the switch on the side and my husband will not die tonight thank you very much!!!

 

[Guest]

Thank you so much. I've tried everything else that has been suggested online and nothing worked. I done what you said three times and it worked. Thanks again.
