I cannot access files on the SD card. Says the card is read-only. Root access says it's read only. This is through Root Explorer.
When hooked to the computer, computer does not recognize it. Nothing happens.
I tried to unmount then mount through the phone settings but nothing happens. I noticed that in the settings, under "SD and phone storage" the Available Space says "23.15GB (Read-only)."
Everything was working fine up til today.
I don't think I hit anything by accident. What can I do to access the files?
In root explorer up at the top there is a little box that has RO/RW on it, did you hit that by mistake?
edit...re-read post, PC doesnt recognize either? Do you have a adapter, remove card from phone and use adapter to put into PC. Card could be toasted
ON Windows7 it asks to repair cards when mounting them, that may help too.
don't know if you tried this already, it might help: when you go to root explorer on top of the screen you should see r/o or something like that tap it and it should change to r/w that will give you read and write right.
didnt see cordell12 answer, beat me to it +1
What is the specific card in question?
i think its a 32 gig cause he said 22 free but if the button doesnt work take out the card and try it again but the button is a dray bubble at the top
I'm having the same thing going on with my stock evo card. Don't believe I did anything by accident either, just randomly happened

Hey everyone first time poster here. I have been researching the question I have in the forums and have not found an answer to my question yet so I figured I would just ask it. I just recently bought my htc evo and tried transferring a SNES rom over to my evo from my PC. At first my computer would not recognize that I was trying to have my evo seen as a disk drive (yes I did have it set to disk drive and not to charge only or another option). eventually it worked (I dont even know what I did, if I did anything at all). After I put this ROM onto my phone my sd card is mounted as read only (cant get it back to write), and no matter what I do I cant get my computer to read my phone as a disk drive. I tried changing the disk drive to another letter which didnt work, under device manager my computer recognizes I have an android phone plugged into my computer, but it still will not show anything in the "my computer" folder, it sees I have a device in, but I click on it and it says "please insert a disk into removable disk F". If anyone can help with this I would greatly appreciate it and thank you for taking the time to read all of this.
Well the first thing to make sure of is that after plugging in the device you go to the notification bar and press on the USB Mass Storage notification, then select "Turn on USB storage". If you've done that simple step and it still doesn't see the SD card, then very simply try a different USB port on your computer.
Even if your card is in read only mode, you should still be able to read it
I don't know why it would be in read only unless you forgot to mount it with read/write after an advanced command.
interesting, I have never seen the option of "turn on mass USB storage" when I've gone to the notification bar? In my notification bar I have a picture of the sd card with a question mark over it. When I drop down the notification bar the notification pertaining to the sd card says "mounted readonly" and the explaination says "The SD card has an unexpected problem. Tapping...." I have no idea what it says after that as it wont allow me to view the rest of the explanation.
As for the problem that this is causing is that it seems I cannot save anything to the sd card. The camera stops working to where I cant take pictures, or download music, and I'm assuming that its because these functions need somewhere to save the files and since the card is on read only nothing will be allowed to save on it?

theres probably an error on the sd card, may need to reformat if its from a different phone too. Try to reformat, probably the only thing possible right now. But before you do that, go to your settings and enable usb debugging and see if that works first to allow your sd card to mount to the pc. Then it should be read as a drive. if not, your gonna have to reformat. so try this, if not, I can try to trouble shoot you more......
thanks for your reply. And yes I shouldve said before that I tried the USB debugging feature as well and that didn't do the job either. I saw reformatting as a suggestion in another thread but didnt see information on how to do it and that is out of my realm of knowledge. If you could explain to me how to do it I would greatly appreciate it.

yea, no problem man, just go to settings>sdcard/sd>unmount the volume>reformat!
let me know if that works for you if not, something else is wrong.
well I go into settings> SD phone & storage> Unmount SD card, is something supposed to happen or am I supposed to do something else? After I tap that nothing happens and the "format SD card" option isnt highlighted meaning its not even an option to choose.
Hmmm. Unmount then remount then umonint again turn the phone off and on see if the uloption highligjts

oh wow that worked man!! Thank you so much for your help, you just saved me a bunch of frustration, now it shows up as a disk drive on my computer and the sd card is read/write compatible. Can't thank you enough man, do you happen to know of a reason as to why this would happen? I mustve set it to be like that somehow I just can't imagine how I did that. Also is there an app or way to back up all your files and apps on your phone and sd card and transfer them to your computer just in case something like this happens again at least I'll have backups so I wont loose everything.
Glad i could hel you. Ita no problem that you cant thank me enough, just as long as we solvee tue prob. You Could have dropped your phone and it knocked the SD card around or it just didn't read it correctly on boot. As far as I know, I don't know of any apps to backup SD card contents and phone data. I would just make a nandroid backup and store on PC. So if you make any vital errors, u can restore using your recovery agent.

Every time I plug-in the phone to the PC, it deleting all the apps on the SD card, What should I do ?
Give it a few minutes after you unplug your phone, they should come back. They're not getting deleted. When you plug your phone into the computer, it unmounts your sd card. That means all of your apps that are on your sd card lose their link to the phone. Once the sd card remounts and is completely scanned, the apps are relinked.
I steal have the apps, i just cant enter them, i know what i am saying

This can usually be avoided by unmounting the phone on your pc FIRST (by right clicking the directory and choosing "eject", or by using the icon in the bottom right on the task bar, assuming you're using windows).
Then you should unmount from the phone by selecting "unmount usb storage" or something like that, from the phone itself.
Only when you've done both of these things should you disconnect the cable from the phone. I follow this process every time and I never get the temporary sluggish behaviour after unmounting.
I picked up my phone looking to download a new ROM to it but then found that my ES File Explorer (given root permissions) was not able to view my external SD card via the mnt folder. At the same time, I was trying to back up my apps and such via Titanium Backup but it said that it couldn't backup anything because my card was full (it's default save location is my external card). It just said "Empty". I went to check my Settings to see if my card was somehow unmounted, but nope, it said it was still there. Even said that I had 11.27 GBs left out of 29 GB or whatever and gave me the usual options to Unmount and such. I pulled off my battery cover and the card was still there, so I assumed that the Android system might just need to sit for a while and cool off while off. Then I turned it back on to find that ES was still not able to view the contents of externalSDcard. So I went to my Root Browser and it too said that no files were there. I then went into my Settings and now it just says "Insert SD card".
I've had this happen before on other Android phones so I did what I normally do and hook it to my PC and reformat it. Windows found the device when I attached it via a SD card reader (the big fat kind like in your standard camera), it didn't want to format it. Windows brought up the prompt and said that it only could format 1GB so I knew Windows wouldn't be able to recognize it. I even tried formatting it via Command Prompt and typing "Format G:" and it too said there was only 1024MB to be formatted then went through trying to format and then said it failed.
I then tried pulling up Ubuntu's Disk Utility to format it. At first, Ubuntu wouldn't even correctly identify the device! Then I got the Disk Utility to recognize it and it couldn't even recognize how many GB/MB were originally on the card! Trying to format just brought up a message telling me that it couldn't do anything.
I had this happen a few times with my HTC Evo 4G OG but was able to format the card and put it back into my phone and have it work. Of course, the last time with my old 16GB card ended with it being destroyed much like this.
Please tell me that I can do something to fix this. Anything?!?!
This card is a 32GB Class 10 Patriot. This has happened before in my old HTC Evo 4G OG with a 16GB Class 4 SanDisk card. That card became unusable after a few times of this happening except I was able to fix it those times using the methods I tried above and allowing my phone to recognize the card again.
Hello,
I have a problem with my SD card, my G3 doesn't recognize it anymore (I have it since about a month).
I did restart it a few times but nothing changes, when I go into recovery mode, everything is in place (I can access it and all my files are shown on the sd card) but nothing shows up when the phone is on (in my musics, photos, and I tried root explorer or ES explorer, it doesnt even show the card).
If I put it off the phone, it says that the card has been removed, and if I put it back on, it says that a card has been inserted, but without showing anything of it.
I'm rooted stock ROM by the way.
I think I did nothing really particular since yesterday, what may be the cause ?

Try this.............
I suggest everyone with SD card issues on their G3 follow these instructions!
I popped the card into my card reader and inserted into my PC. Right-click and select "Format". Set format type to "NTFS" and cluster size to "32kb". Uncheck "Quick Format"!<<<Important!
It took almost an hour to format my 128gb card, but gave me the "format successful" prompt when finished. When I popped it back into my phone, it immediately prompted me to format the card because NTFS is an unrecognizable format for the G3. This is kind of the point. It resets the card in a way that simply erasing it's contents from the storage menu wouldn't do.
I dit it and it works now perfectly fine; thank you !
Also it worked for me but with quick format. :good:
I have an extra SD card in my phone where i store my music.
Now since a few days i cant add OR delete anything there. If i select an mp3 and want to delete via Explorer on PC it says its write protected. On phone there isnt even an option to delete it. Wtf..
I also cant add any mp3s anymore. It starts to copy, but then just nothing happens. Any ideas? Im rooted, Android 7 stock
Same problem here. Did you find any solution?
You should mount your sd-card as read/write
