USB被Write protected了，求助..

[玫瑰花]

UBS一直用的好好的，突然插进电脑后，就说WRITE PROTECTED了，文件不能修改了，也不能格式化了，只能把原文件复制走了...
有高手可以帮助么？谢谢啦

简单，把那个高出来的小东东按下去，走到解锁的位置就行了。

There are 3 methods to solve the problem:

1. Maybe there is a switch on the USB. Locate a small switch at some place on the USB drive, and switch off it to remove USB write protect.

If there is no protect switch.

2. -- Open Registry Editor by typing regedit in Run dialog.
-- Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\.
-- Find a sub key inside it named “StorageDevicePolicies”. If it does not exist there then you need to make it. Right click on “Control” key -> New -> Key. Name it “StorageDevicePolicies” without quotes.
-- Now right click on this newly created key and then click New -> DWORD value and name it as “WriteProtect”.
-- Modify this key and give it a value 1.
-- Click OK, and remember to restart the PC.

3. Download tools http://www.softpedia.com/get/System/Hard-Disk-Utils/HDD-Low-Level-Format-Tool.shtml, or http://www.box.net/shared/9hgp81ndgs to format USB driver.

After the low level format, you may need to “Partition the drive“. Partitioning a drive means allocating it its File System and Cluster Size that was lost after the Low Level Format.

For that:

1. Run diskmgmt.msc in Run.
2. In the disk management window, select the pen drive, right click on it and click on Format.
3. Now choose the File System and Allocation Unit Size and do not check the boxes below.

Click OK and the drive will be reusable after this.
