Is it the same on other computers? If not format it on there.

Always pop back and let us know the outcome - thanks

The obvious question is this. Is there a mechanical lock on the drive?

I am guessing you want to preserve the existing files and add more? First let me say that flash media is the least reliable of any storage methods. That said, you should always maintain at least 2 copies of all files you value.

Try viewing the pen drive in Windows Disk Management. Post all the information listed there for the pen drive.

The link below states that series was discontinued in 2013. So the drive is at least 4 years old. That would indicate many read/write cycles. Flash media has a finite number of cycles before failure.

When in Disk Management you MAY have the option of Deleting the partition/s and formatting the pen drive. That of course will make the files inaccessible.

Have you tried copying the data to a folder on your computer? Write protect should allow that if the file system isn't corrupted.

And if all the above doesn't work, it's possible the drive has given up the ghost, IE. It died.

To preserve existing data many flash drives will enable a special read only mode when specific types of errors are detected. This is typically not reversible. In some cases this can be reversed but you would have an unreliable drive.

If I had a drive that could not be brought to normal operation by normal methods I would replace it.

As mentioned flash drives are the least reliable of modern storage media. For them to fail is not unusual.
