I have a perfectly good 4 gig USB stick that has suddenly become read-only, and it will not format on Windows 7 machine or on my Dell XP-SP3 Pro.
Somehow this stick has been marked READ-ONLY, and that has nothing to do with any registry setting. I found no entries in the Registry that said "Writeprotect" or that had any values for ...policies. I can read files on it, but I cannot write to it, and it will not format. If I plug in a different USB stick, I have no problem.
This device is connected via a USB extender. I believe it became "read only" one day when the extender accidentally disconnected, and I plugged it back in.
Anyone have any suggestions for how to un-protect ir, or reformat it (it cannot be reformatted because it is write-protected!).
