If you are unable to edit or save files on your USB drive, it is likely that your device is locked in read only mode. This article will introduce you to a few ways that you can unlock write protection on your USB key so that you may edit your documents as needed.
How To Unlock a USB Drive
Many USB keys come with a switch that slides up and down to enable or disable the write protection lock. As a first step, we recommend that you verify whether your USB has this switch (normally labelled with a hold or locked option). If so, simply unlock the switch and attempt to write.
Another simple solution for disabling write protection is to simply ascertain whether or not your currently file is being viewed in Read Only format. If it is read protected, simple right click on the folder and uncheck the "Read Only" button.
There are many online recovery tools which are related to a specific brand of USB stick. For example, utilise the JetFlash Online Recovery tool to repair Transcend USB keys which gives the user the flexibility to either maintain stored information or the format key.
