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!).

Thanks.

I will check this out right now. But in any case, what might be going on with my thumb drive? I've never (before this!) heard of being able to write-protect a thumb drive.

When I tried to install the file you suggested, I got a warning from my firewall (Comodo) about an unsigned certificate or something like that, so instead I downloaded and installed the HP utility that formats a thumb drive. When I tried to run it, it (the HP software) wouldn't proceed, saying the thumb drive was write-protected.

Any suggestions?

The flash drive might be shut. Try another link as the previous may be flagged. http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/
