I posted around November last year about how my Kingston DT Mini Fun 2gb flash disk suddenly went wonky and deleted all my files telling me I had to reformat it but its write protected. I was just checking something a while ago when I saw a comment to that entry by someone named, arthur iakab. This is what he said:
I found this on another site and it realy worked. It erases everything from it but make it work after that But pay big attention DO NOT have any other device conected to USB port as it is going to erase all from it:
My kingston flash drive had the following symptoms:
- Could read data
- Couldn’t write/format (”write-protection error”)
- Every file had the “archive” flag set. (attrib command in dos prompt)
It was fixed running the low-level formatting utility from Apacer website.http://www.apacer.com/en/support/downloads/Repair_v2.9.1.1.zip
(named “HT203 Handy Steno 2.0 Repair Tool” – or XXXX Repair Tool, for the software is model/manufacturer independent.)
Be careful to have only the flash drive you need to repair connected to your computer, as the software is quite ‘interfaceless’, and doesn’t even allow you to choose which drive you want to format – seems to me it assumes the first removable drive available.
Wish you guys the best of luck.
I tried it just now and it works! *SQUEALS* At least the flash disk can still be used now, I an go give it to my sister. She needs it more than I do now. 
So in case you get that nasty write protect error even if we all know there isn’t a write protect hinge in that little flash disk, try the repair software above from Apacer and make sure to follow what Mr. Arthur Iakab said in his comment above. =^.^=
So to Mr. Arthur Iakab, THANK YOU, THANK YOU, THANK YOU! -huggles-
