Remove Jet Flash Write Protection

Insert the mini CD that came with the USB Flash disk. Start JF Utility.exe in the JF Utility directory. If it complains that the disk is write protected, choose "Continue" Choose "Partition" Answer "Yes" to losing all your data (Since this becomes a problem usually after formating the disk in WinXP or Win9x, you will most probably not have any data on there in any case) Choose "Public Area Only (Single Partition)", Then "OK", Then "OK" again. Unplug the device, reinsert device, and voilà!- no more dark secret areas or write protection on your disk!

Transcend makes several... which do you have? They even make some that have fingerprint scanners in them and if your not the original owner, you can't unlock it.
