It may already have happened to you, especially on older USB drives, to try to copy a file on it and get an error message regarding the only possibility to read data (and not to copy it over).\u00a0Not only that: sometimes the error also concerns reading. Write Protection On USB Sticks: How To Eliminate The Problem Under these conditions, support is completely useless.\u00a0However, this does not mean that it is not possible to save the situation anyway.\u00a0The ways to follow are different and, it must be said, in some cases, they can cost all the data present on the support. some of which are easy and painless, others more definitive, which erase the contents of the memory, formatting the protected USB key. First, Check The Block Switch If you have problems with a card or USB stick, the first thing you need to do is to check that the\u00a0lock\u00a0switch\u00a0is in the correct position (some USB drives have the lock activated to protect the memory from the loss of important data).\u00a0If this is available on the media in question, it may have been moved only accidentally. Regedit In any version of Windows, from XP onwards, run\u00a0Regedit.\u00a0Click on Start, in the search box, type\u00a0regedit\u00a0and start the program.\u00a0The window that opens up in front of you will closely resemble a\u00a0File Explorer.\u00a0Then follow this path:\u00a0Computer \\ HKEY_LOCAL_MACHINE \\ SYSTEM \\ CurrentControlSet \\ Control \\ StorageDevicePolicies. Then click on the\u00a0WriteProtect\u00a0value\u00a0in the box on the right and edit the value data from 1 to 0. Then click\u00a0OK\u00a0to save the change.\u00a0Close Regedit and restart your computer before connecting the USB drive again: with a little luck it should go back to work. Now you can continue using the unit, but it\u2019s worth copying the files you want to keep and then formatting the media before using it again. StorageDevicePolicies Missing?\u00a0Here\u2019s What To Do If you can not find\u00a0Storage Device Policies, you can create the entry by right-clicking on the white space in the\u00a0Control\u00a0folder\u00a0and choosing\u00a0New\u00a0\u2013\u00a0Key\u00a0and enter the name StorageDevicePolicies. Now double-click on the new key (it will be displayed graphically as a folder) and right-click the white space again and choose\u00a0New\u00a0\u2013\u00a0DWORD.\u00a0Call WriteProtect and set the value to 0. Click\u00a0OK, exit Regedit and restart your computer. Diskpart The methods shown up to now have not led to results regarding the removal of the write protection on USB sticks?\u00a0There is still an attempt you can make before you notice the physical damage of the support.\u00a0With the USB drive or memory card connected to the computer, start the\u00a0command prompt\u00a0(from the Start menu, look for cmd.exe or command prompt). Note: it\u00a0may be necessary to run cmd.exe with administrator privileges if a message about access denied is displayed.\u00a0To do this, right-click Command Prompt in the Start menu and select\u00a0Run as Administrator\u00a0from the menu that appears. Now, at the prompt, type the following and press enter after each command executed: \tdiskpart \tlist disk \tselect disk x\u00a0(replace X with the letter assigned to USB support) \tattributes disk clear readonly \tclean \tcreate partition primary \tformat fs fat32\u00a0\u00a0 (you can exchange FAT32 for NTFS if you only use support on Windows devices) \texit In doing so, in addition to formatting the media, the USB stick should (or any other type of media) should be back in full form. Physical Damages? This is the worst hypothesis, but it should be taken into consideration.\u00a0In this case, there is very little to do, if not replace the damaged device.\u00a0If the problem is only writing, you should save the data present as soon as possible. If the problem is also reading, you can try some methods to save the file.
