Problems about write protection in Win7 system

This is probably the case:

One day, the hand is cheap, in win7 the process of opening the Disk Manager, the original is to see their own mobile hard disk mount to the system did not, but suddenly do not want to see, forced to unplug the hard drive. The result of the tragedy happened, his mobile hard disk again plugged into the computer, can not copy file in, also can not delete the file, but this hard disk on someone else's computer can be deleted operation. (This, of course, does not necessarily happen.) It's just that I've been through this kind of situation. This is the so-called write protection (System permissions) problem.

The workaround is as follows:

Look up the information on the Internet to find a way to solve the problem.

First of all, I saw some posts on the Internet that are to change the registration form, 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 needs another solution.

is to use the DiskPart command.

In the cmd (Administrator Morse) command line, enter:

C:diskpart

Rom list all the hard drives, in order to view we're going to remove the write protection disk is that

Diskpart>list disk

Select the disk you want to manipulate, 1 represents my mobile hard drive

Diskpart>select Disk 1

Remove write protection

Diskpart>att Disk Clear ReadOnly

End exit

Diskpart>exit

Here also to illustrate a point, I am now to remove write protection, if you want to write protection to the hard disk? Just use clear, switch to set. But here to add write protection to the system is only effective, hard drive put on someone else's computer is not write protection, to think of your mobile hard disk in other people's computer function, it is necessary to write protection on the volume (just to disk settings).

DiskPart

List Vol.

Select Vol J

ATT vol. set readonly

Well, this is a bit of a harvest today.
