A practical way to solve the write protection of Windows 7 system

One day, handcuffs, in the process of opening the disk manager under Win7, originally wanted to see your mobile hard disk mounted on the system, but suddenly Did not want to read, forced to unplug the hard drive. As a result, the tragedy happened. After the mobile hard disk was plugged into the computer again, it was impossible to copy the file and delete the file, but the hard disk could be deleted on someone else's computer. (Of course, this situation does not necessarily happen. It is only my situation that I experienced). This is the so-called write protection (system permissions) issue.

The solution is as follows:

Check the information on the Internet to find a way to solve the problem.

First of all, I saw some posts on the Internet saying that I am going to change the registry, which is only suitable for the early windwos operating system. After vista (vista this is my guess, based on Win7 is Vista upgrade) including Win7 requires an additional solution.

is to use the diskpart command.

In the cmd (admin Morse) command line, type:

c:diskpart

List all the hard disks, in order to view the disk we want to remove the write protection Is the

diskpart>list disk

Select the disk to operate, 1 represents my mobile hard disk

diskpart>select disk 1

Remove write protection

diskpart>att disk clear readonly

Ending exit

diskpart>exit

Here is a point, I am removing write protection now, if Add write protection to the hard disk? Just use clear, change to set. However, the operation of adding write protection here is only valid for this system. The hard disk is not write-protected on other people's computers. If your mobile hard disk works on someone else's computer, you must write protection on the volume (just right) Disk setting).

diskpart

list vol

select vol J

att vol set readonly

Well, this is a bit of today's gain.
