SD card read only, also known as SD card write-protected, refers to a memory card or micro SD card that you can read, however, cannot modify data on it.

SD Card Read Only Symptoms

Usually, a memory SD card or USB flash drive itself has been locked into «read only» mode; it’s because the card is getting old, damaged, corrupted, or infected by a virus. Sometimes, human error will also make SD card read only.

When your Android or camera external SD card mounted as read only, it will prevent you from writing, deleting, copying or moving data on it. Here we’ll teach you how to fix a read-only SD card to read-write by [1] checking the write protection tab, or using the [2] Windows command, [3] automatic write protection removal software & [4] a third-party FAT32 to NTFS converter. As long as you successfully remove read only from the SD card, you can go on formatting the SD card freely as you want.

Most memory cards for Android or Nintendo Switch use are usually with a physical write protection tab. If you find such a tab on your card,В then first you need to slide it to the unlocked position to remove the read only attribute.

Step 1:В Take out the memory card that is currently in a read only state from your device.В

Step 2: Check if there is a physical lock switch on it.В

Step 3:В Position the lock switch from ON to OFF and unlock the SD card.

Method 2. Remove Read Only from SD Card Using CMD

Step 1: Plug the read only micro SD card into Windows.

Step 2: Click «Start» > «Run» and enter cmd.

Step 4: Type list volume. Now you’ll see all your connected drives, see which one is the memory card drive.

How to FormatВ Read Only SD Card to Normal

Many people tend to format a memory card when mounted as read-only on their Android phones. However, you all end up with failure because of the error that Windows was unable to complete the format, just like how Windows Disk Management fails to format a write-protected SD card. Only when you removed the read-only attribution on the SD card, you can then format it and restore SD card full capacity.

It’s easy to format a read-only SD card by using EaseUS partition manager software again. Just plug in your SD card with theВ read-only problem that you have fixed and follow the simple steps to get a full fix.

Step 3. Click «OK» on the pop-up window to continue.

Step 4. Click the «Execute Operation» button on the toolbar, then click «Apply» to start formatting your SD card.

By formatting an SD card that was mounted as read-only can help restore its full capacity and make it work as a new storage card.

You can move partitions around, resize them, defragment, and more, along with the other tools you’d expect from a cloning tool.

android studio put itself into read only mode for all files #2994

Comments

james-lawrence commented Dec 23, 2018

Steps to Reproduce

standard development for flutter, somehow android studio decided every file was read only (which was not the case). seems clearing .idea directories fixed the issue. but this sort of behavior isn’t acceptable.

begging that flutter move away from android studio as the defacto development environment. its extremely fragile and brittle. to the point where everytime I’ve tried to use android studio I spend more time debugging the IDE than actually writing code.

Version info

The text was updated successfully, but these errors were encountered:

Sorry you had this experience. It would be great for us to track down what happened so please do share whatever context you can. Certainly if this recurs.

Again, this is really unfortunate. If you have any actionable feedback we can pass on to the Android Studio team we’d be happy to.

Thanks again for the report and do check back if you hit any other issues.

PS: we’ve had a few quick releases of the flutter plugin since 31.3.1 to address a number of issues. Worth an update for sure.

EDIT: Sorry, misread. You’re up to date.

james-lawrence commented Dec 25, 2018

problem is I’m not even sure how to debug these issues. android studio is extremely opaque regarding errors.

pq commented Dec 26, 2018

@alexander-doroshko : any suggestions that may help debug AS in general?

alexander-doroshko commented Dec 26, 2018

To narrow down the «read-only mode» problem I’d first ask what the problem looks like.
Was it a dialog saying ‘You are trying to edit non-project file. Are you sure?’? If so then it means that the project structure somehow got messed up and the files appeared to be outside of the configured content roots.
The root cause might be the same as in #2993. My guess is that it could be related to Gradle. I’m not an expert in Gradle, neither in its support in the IDE. Just a guess: on Gradle project reimport all the current IDE project configuration is wiped out and reconfigured from scratch based on gradle config file. So content roots might be changed as well as module dependencies, which means that knowledge that that was a Flutter project gets lost.
The cause might be different.

james-lawrence commented Dec 26, 2018

@alexander-doroshko the read only mode presented itself when editing the files themselves. AS would just ignore my input and display a little note saying read only. i ‘fixed’ the issue by deleting gradle and .idea caches. havent been able to reproduce it. #2993 still happens all the time though.

Not sure I understand. Should you see it again please paste a screenshot. Thanks!

Speaking of #2993, Gradle reimport is probably deleting knowledge about Flutter from the IDE project files. Gradle doesn’t know anything about Dart/Flutter, so maybe Flutter projects shouldn’t be backed by Gradle config. Sorry, not my area of expertise. Not sure I can help much with it. I think responsible developers might be interested in a sample project they could use to reproduce the issue.

Since no one ever provided you with a screen shot here it is. Every file in Android Studio is locked, I cannot edit anything. BTW I know that the res definitions as shown in this example are wrong, I was working on fixing the issue when I suddenly am no longer able to edit any file.

The little popup message happens on any edit action, such as hitting enter or any other character.

EHBradford commented Apr 8, 2019

I continue to have this issue. Have tracked it down in Android Studio 3.3.2 to when I go to Open Module Settings (F4) and I create the APK module, press Apply, and then Ok all of my files are now locked with Android Studio.

To restore my ability to edit the project I have to Re-import Gradle Project. But as soon as I do that I loose all of my «Modules» that I created using the Open Module Settings (F4) window.

[SOLVED] [ANDROID] What to do if sd card is mounted read-only/can’t write to the sd card

This info may help you if the following is true:
— up until now you�ve had no issues when using your sd card
— all of a sudden you can no longer write to the card, perhaps along with an error message being reported that indicates the sd card is mounted read-only

This is another one of those situations where it is not necessary to take extreme measures such as doing a complete reformat, or outright replacing the card�as suggested in the many threads on this subject.

Here are the facts. Your sd card�s file allocation table (FAT) has some kind of error. It�s an android-thing that crops up once in a while. Because of this FAT error, the card automatically gets mounted read-only, and no matter how many times you go into settings and try to unmount/remount the card, it is to no avail.

Fix the FAT
— connect device to your PC (USB connection) and make sure it�s set so that you can copy files to/from your computer (on my device in the notification panel there�s an option to do this under �USB connected�)
— on your pc, open windows explorer (or click on start->computer), then right click on the mapped drive to your sd card � you may have to wait a minute or two for the mapping to take effect
— select Properties
— select Tools
— select Check now� (for error checking) to automatically fix file system errors (no need to deal with bad sectors at this time)
— when completed (takes a minute or so), the FAT will be in working order once again. No files are deleted during the process, so no need to worry about that.
— safely disconnect the device from your pc, at which point the sd card will now be mounted read-write and you�re good to go

Omg thank you sooooo much i rlly appreciate this i had this prob for a while u fixed it thanks you.

what? your doing somthing wrong, what support center? you don’t have to open any support center?

If you have the FAT problem more than once, it could be an indication that the card is going bad. (The FAT is one of the most written-to areas on the card.) At that point, make sure that you have every single file that you may ever want backed up onto your computer. Then when the FAT finally goes bad (and if it’s a good manufacturer, they may even replace the card for free), you won’t lose your data.

Remember, even though SD cards have a huge number of write cycles, it IS a finite number, and every SD card will eventually go bad. You can replace the card, but you can never replace the picture of your granddaughter’s first step. Data you don’t have backed up to at least 2 independent places is data that you really don’t need.
