How to write protection for USB stick

Recently, a lot of users asked why the U disk will be written to protect the U disk write protection to do, how should it be lifted? U disk write protection, the files on the U disk can only be read can not be deleted, can be modified but not saved, although the virus is very effective, but also to the user has brought trouble. How to solve the write protection of U disk? So today's small series on this phenomenon to introduce three quick solutions, for reference only.

The first method:

1. Download USB Cleaner (online search can be downloaded), then open run;

2, then choose USB cleaner– "Monitoring Program –" other functions;

3. There is a – "Remove the Write-protected option, then select Browse Letter, then click Remove Write Protection

Finally OK, try to see if there is a lift.

Note: Confirm that there is no write protection switch of the U disk, there is a switch directly open write protection can, without repair,

The second method:

One, My computer (computer) Right click on the mouse-management-Disk Management-Select the USB stick right-click to delete after formatting.

Second, modify the registry (because modifying the registry is the last thing I do, do not know whether the "other methods" in the two steps to its role, please do the registry modification method after the invalid conversion format and modify the policy operation)

1. Open the registry Win+r (that is, start-run) type Regedit.exe

2. Enter the following directory Hkey_local_machinesystemcurrentcontrolsetcontrolstoragedevicepolicies

If there are no storagedevicepolicies entries, this is established

3. Establish a DWORD value named Writeprotect and make it a value of 0

4. Restart

The above is the general operation, but in the actual operation, such as the above operation can sometimes solve the problem of write protection, for this problem the author has done the following actions

5, restart with a U disk restart, when the system restarts to the flash drive, unplug the USB flash drive

6, the system restarts after the insertion of a U disk, u disk operation returned to normal

Hkey_local_machinesystemcontrolset002controlstoragedevicepolicies; Hkey_local_machinesystem

The Writeprotect value in Controlset001controlstoragedevicepolicies is also changed to 0;

The third method:

FAT32 to NTFS

1, Win+r input cmd.exe (that is, start dos,windows inside) can also be attached to the command prompt;

PS: In addition to modifying the registry method can only be used to solve the write protection of the U disk, please choose carefully, it is best not to convert the format operation, if the format conversion, FAT32 to NTFS data will not be lost, to restore normal after the USB stick can be formatted to FAT32, FAT32 to NTFS conversion simple, But the reverse is troublesome, and the data is easily lost after the transfer.
