Xbox and Sony PlayStation in Belgorod

Yesterday, helping a friend remove superfluous information from a computer, it came to removable media, in particular memory cards and flash drives. And I came across a situation when, when I try to erase files from microSD for a smartphone, the microSD card is not formatted, an error is issued: “The disk is write-protected”. In the article I will describe the methods that I resorted to in order to fix the problem, maybe they will help some of you.

How I Unlocked a Memory Card

Drive management

Using the Win + R hotkeys, open “Run” and enter the diskmgmt.msc command. In the list of volumes, look for the connected external storage medium and click on it with RMB. And then, as shown in the screenshot below, and in the pop-up context menu, select “Format”.

Using diskpart to format an SD card

In the search for “Start” we write cmd.exe, this command will open a command prompt. We hammer in “diskpart” (without quotes). Using the keyboard, type in list disk.

In the table we find our SD, we recognize it by size.

Now use clean.

Within a short amount of time, the data will be deleted.

Next, be sure to create a partition, enter create partition primary, then select partition to select it and active, in the execution of activation. In conclusion, we use format fs = ntfs, full or format fs = NTFS QUICK, - quick formatting of microSD.

In turn, I want to note - the reception is the best!

Command line

In my case, the work was carried out in the safe mode of Windows 10, but I think that the option described below will be relevant for later versions.

Open the command line, it can be found by opening the “Start”, where we enter - format e:

Where “E”, respectively, is the letter of the volume.

What to do if MicroSD is write protected

Change disk properties

Go to “My Computer”, RMB click on the microSD card icon, which is not formatted, go to “Properties”. We are interested in the “Access” tab, where you need to go to the “Advanced Settings” section.

In the window that opens, check the box “Open sharing” and save the changes. Then, in a standard way, format.

You can remove protection in the Windows registry editor

Using the hot buttons Win + R, by the way, you yourself can create for yourself those that will be more convenient for you to work with, and enter regedit. In a branch

In WriteProtect, change the value from 1 to 0.

If there is none, then you need to create the DWORD (32-bit) parameter, if the OS is 32-bit or DWORD (64-bit) by clicking on an empty space on the right side of the screen.

Changing the file system

If you can’t copy files with MicroSD over 4 GB, then it may be in the limit of the file system - replace FAT 32 with NTFS.

After such manipulations, everything should work out.

Diskmgmt.msc utility

This action also applies to flash drives.

In the window we are looking, for example, our flash drive

Using the mouse we perform actions.

How to remove write protection through the policy editor

  1. In “Run” we use gpedit.msc
  2. Computer configuration - “Administrative templates” - “System” - “Access to removable storage devices”.
  3. And turn off “Removable Drives: Deny Read”.

What to do when none of the options fit

  • Apparently a breakdown in the memory itself.
  • Check your PC for viruses.
  • The problem often arises due to installed programs for creating virtual drives, such as Alcohol 120%, DAEMON Tools, Virtual CD, Virtual CloneDrive and their analogues.
  • It's about flash drive or SD firmware (use proprietary software, such as the Hp disk format tool or HDD low level format, which is often available on the media or can be downloaded from the official site).

Thanks for the tips, but I have the following similar problem. There is a 64 GB flash drive formatted in NTFS. I transfer the hoofing (films, music, photos, etc.) from one computer (with Win XP Pro OS) to another computer (with Win 7 OS) - and almost always the flash drive becomes unreadable, not copied - with a message - unprotect it. This can only be fixed by formatting the flash drive, but then all the information on the flash drive is lost. One computer from each other is more than 50 km, it is not possible to send information over the Internet. After a again formatted flash drive works fine. By the way, I noticed that this only leads when I transfer information from Win XP Pro to Win 7, but not the turnover.

Good evening! How everything looks like !! In linux, format the flash drive command: sudo mkfs.vfat -F32 -I -v / dev / sdb, and in FREEBSD a similar command: sudo newfs_msdos -F32 / dev / da0.

I have been dealing with such a problem for half a day and all these tips did not work. I started looking for a proprietary utility for controlling the memory and the memory itself and still found it and is now formatting it using it. To determine the data on the flash drive, I used the utility ChipGenius v4.00.0807 (it could only see, other similar utilities do not see the flash drive). It took 1 hour 15 minutes to recover. , you can wait, the flash drive is live completely.

That's what I like Transcend flash drives, because they are adequate prices and a program for “repairing" flash drives, which is downloaded to each medium. ChipGenius, a good program, also helped out more than once, but it does not contact all manufacturers.
I often use: JetFlash Recovery Tool, MPTool, USB Flash Drive Recovery.
And the best thing is to try to search, as you do right, on the product’s official sites.

ChipGenius is a program for determining the controller and the type of memory, and then you need to look for a proprietary utility for flashing the controller and formatting the memory. There may also be nuances, you need to try old and new versions of programs, for example, the old version of the program helped me, the new one did not want to work with a flash drive, although everything was determined and the memory was set up, but the START button was not available. In programs, you can change something, you can even sew your name, change the mode of operation of the LED indicator. Available languages ​​came across: Chinese and English. The description of the work is in PDF in Chinese, but can be found both in English and with Russian tips on what to do.

Today I tried ChipGenius. Live and learn! Great program. Thank you Vladimir!

Please Sergey! It never hurts to try something new.

In this regard, I am only “FOR”. Will be that interesting, toss. ,)
