SanDisk CruizerBlade 64g

Looks like a familliar story.

Write Protected. no longer usable. 

Is there any answer to this seemingly common problem. Looks like a MBR issue.

Tried the usual DOS diskpart gets to ‘Clean’ and no further. Tried regedit wrote new Key, With Dword 0, rebooted here and there.

Had good help in my Football forum but no answer to fix the WP .

Have replaced with another make, but, as it was only usd so little I just wondered what is going on.
