One SanDisk Ultra USB 3.0 32GB drive decided it was time to be write protected. Diskpart showed that the disk was currently in a read-only state.

After a number of attempts suggested by Internet I decided that it was time to give up and give in to the dark side.
This was a FAQ entry at EMTEC:
My flash drive doesn't work / My flash drive is write protected HOME › FREQUENTLY ASKED QUESTIONS › USB FLASH DRIVES
The download link is also dead but I found a program that fit the description. Ignoring the "certify" part and following the instructions I now have a working SanDisk USB drive. An empty one but at least I can use it to unimportant file transfers.
This is a copy of the program. Use at your own risk...
I will never buy a SanDisk USB drive again.

You are aware that this could happen to any flash drive regardless of manufacturer, right?

I have had the same issue and sent it off for a replacement.
Why are SanDisk USB drives setup with this unremovable write protection? not very user friendly is it.
