I have an edge Cruzer 4GB USB flash drive, used only for a few days and all of a sudden it keeps telling me what is write protected. knowing what does not key to the locked
what is there anyone who had the same problem Is there a good solution or is the key and burned
help me
thank you
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.
- In My Computer, right click on the drive letter of your SD card and
- Eject it.
- Then pull the card out and stick it back in.
- Try to write to the card. If it works, GREAT! Proceed with your copying.
- 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.
