i have the same problem of (the disk is write protected, ...) with Kingston data traveller II Plus 1GB, the same like you, can NOT move or delete or edit or create new files on the drive although it has sufficient space.
i have tried even formating under Win XP Professional with service pack 2, and Win 2000 Service Pack 4, and even under DOS and using Partition Magic, but always recieve the same message of WRITE PROTECTION - i looked for any option to remove a write protection in the settings and properties in Device Manager, but NOTHING
and no solution also on kingston FAQ we page - nor in Win XP help
i've just sent e-mail to Kingston technical assitant
PLEASE if any one can provide help .....
Hey,
I had got a Meritline RIST watch sometime around march'05 with 256MB of data storage on its inbuilt USB drive. I've formatted it with a secure (password-protected) partition and a non-password-protected partition. It had been working fine since yesterday. I was transferring some files from the watch to my PC, deleting those files from the watch, adding files to the secure partition...Suddenly, when I tried to delete or copy anything on the watch, it showed the message that "The disk is write-protected. Remove the write protection or use another disk." I can still copy data from the watch to my PC, but cannot modify the contents on the watch. For the reason of being write-protected, I'm not even able to format the USB drive. Please Help!!!
