Good afternoon Everyone,

 

I had a write protected USB drive that i would like to remove the read only attribute.  One problem i have is the original PC that this was put on was stolen.  So i didnt know if there were any software programs that could remove the read only attribute forcefully or could break the read only.

 

Here is what i have tried:

 

1. Plugged USB drive into my new PC.  Ran Diskpart (in admin of course) Diskpart says it successfully removed the read only attribute. But when you run the "detail disk" it shows it has not been removed.  Tried formatting anyways, failed.

 

2. Tried Rufus.  It fails as well. 

 

3.  I have Googled and tried a few other programs that say they can do it, but they fail as well. 

 

 

Don't really care about the data on the drive, i can recreate it no problem.  If the answer is to throw away the drive then that's the answer.  Just wanted to give it one last shot before I shoot it.

 

Thanks for your time, thoughts and input.

I doubt it will work but see if doing a low level format on the drive using the below tool works. Make sure you are selecting the correct device. After the wipe you will need to partition and format the USB flash drive.

Some USB flash drives like Sandisk put themselves in read only mode if they detect a write fault. There is nothing that can be done once a flash drive becomes read only if diskpart cannot remove the attribute outside of there being some mechanical switch on the flash drive itself. Sometimes a firmware flash will bring the drive back but that depends on if firmware is available for the drive or not.

Thank you for your reply.  I tried but did not work.  I guess i will just trash this drive.  Thanks for your help.

 

 

Have a great day!

I have to agree with John on this one.

 

I've had a number of SanDisk Cruzer 'Blades' over the past few years; they're pretty cheap for what they are. The 32 GB and 8 GB models have never been known to suffer from this problem.....it always seems to be the 16 GB models that will flip into 'read-only' mode at the slightest provocation.

 

It was eventually discovered that it all stemmed from a batch of faulty firmware chips that SanDisk had sourced from Hynix. Hynix were aware of the problem, but refused point-blank to do anything about it, citing various legal 'cover-my-ass' type reasons that they claimed tied their hands from doing anything to resolve matters.

 

The eventual advice from SanDisk, following a huge user campaign (and a very long-running thread on the SanDisk forums), was that if you had this problem, then you should return it to them and they would replace it, no questions asked. What the outcome of all this was I don't know.....but it can't have done their reputation any good.

This particular thread was running for nearly 6 years..! The whole sorry business seems to have eventually kind of 'fizzled out'.....

 

The moral of this tale would seem to be to spend a bit more on your drives in the first place.....and to give SanDisk a miss. Although, having said that, I use a number of their Ultra 'Fit' nano-sized USB 3.0 drives (including a pair of 128 GB models as permanent 'external storage' in my elderly Dell laptop).....and those have never given the slightest bit of trouble. Apart from running hot enough to fry an egg on.....but that's another story entirely!
