Read-only USB drive Solved

Question

Hello,

I have a problem with my USB drive. It tells me that the disk is read-only as soon as I try to put something on it. Yet I haven't locked it...

I can't format it or do anything at all.

Could a virus be the cause of this problem?

I tried it on other machines and the result is the same...

Can someone help me?

Hello,
I just spent 2 days trying to unlock my key, which had been blocked after being inserted into a machine that wasn't mine.
After attempting all the functions of "diskpart," "usb-protector," "RMPprepUSB," and more, I had to face the facts: the problem was deeper. It wasn't a blockage that could be removed by simply redefining the key's properties (partition, format, MBR sector, or otherwise). The blockage came from an instruction given by the machine that changed the firmware of the key. The only solution was to flash the key back to its factory version (as it was when purchased). My only advice, after over 10 hours on different devices, is this: type into Google (or another search engine) "flash USB key XXXXX ZZZZ from TTTT," where X is the brand, Z is the model, and T is the size. The manufacturer of the key provides a program that resets the key to its original state. 10 minutes later, the key was functional again. Simple, effective, and ultimately so logical.

Hi, I had the same issue and actually, you just need to remove the "HOLD" (button that is on the USB key).

The solution of the HOLD button made me laugh a lot. But that's because it's the right one ; )

Good evening,

your computer likely already recognizes another device on the same letter as your USB key.
So, in order for your computer to recognize your key, you need to change the letter assigned to it.

To do this, go to Control Panel => Administrative Tools => Computer Management => Storage => Disk Management. Find your USB key in the list, right click on it and then select "Change Drive Letter and Paths..." => Change => choose an unused letter and OK.

Normally, the problem should be resolved, your key will no longer be read-only.

I hope I was able to help you ;-)

And for those who have lost data, or have files with strange names instead of folders, I recommend using software like "Stellar Phoenix." It's paid, I don't know if there are any free alternatives, but for recovering data, it works well; I did it before doing anything else like defragmentation…

• Open the Registry Editor: Start, Run, type regedit
• Search for the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\StorageDevicePolicies
• Create a REG_DWORD value named WriteProtect and set it to 0.

I had the same problem. In Computer Management and Disk Management, there was no partition and it said 'unallocated', so I created a partition the maximum size of the USB drive, it formatted the drive and it was good!
But it depends, the same problem can have multiple causes, so different solutions to fix it.

Hello everyone, I have already tried to create WriteProtect in regedit but after that it doesn't work. Is there another solution? Thanks to all.
