SD card in read-only format - Android Q&A, Help & Troubleshooting

I'm currently using an LG P970 phone with an android ver 4.0.4.
The issue is that out of nowhere, my SD card (SanDisk 8GB) just went into a read-only format. I can't use my camera, apps stored on my SD are now pretty useless, and I can't edit/store/delete files from the SD (via phone or PC).
I think this isn't an isolated case and some people have experienced this with their devices but have found solutions. The problem is I have tried unmounting/mounting the card, error-checking on PC, and even resetting the phone back to factory settings, but nothing seems to work in my case(even the files are still intact, as if they're immortal:saint.
I'm not a "techie" person so hopefully there's a simple solution to this.

(Q) help with sd card problem please!

it says my sd card is blank and it doesnt seem like its mounting.... i took it out and formatted it to fat32 and its still saying blank sd card i did this a bunch of times..
If you formatted it, it is blank. What's the problem?
What does it say in settings/SD & phone storage? Have you tried formatting it there?
tried both put it in comp formatted it put it in phone formatted in there too says mount sd card like its not reading it
and it also said the blank thing when i had stuff on my sd card
so i guess im effed cuase i cant put anything on my sd card phone wont read it so i cant get back to stock...
Try formatting it on your computer or phone, put it back into your comp and put some files on it

i did and i even tried a diff sd card wont read that either
I'm new to this so someone please correct me if I'm wrong but you can download the stock Rom from your phone and use Rom manager to go to stock,there is 2.5g of space on phone
my problem and worry is i wanna get unrooted so i can call and this will prob be covered under warranty and i wont have to pay the rediculous deductable on insurance if i have to go another root...
and also you cant use rom manager unless sd card is mounted i tried and mine doesnt mount
So you have tried multiple SD cards in your phone and none of them work?
yes i have tried a couple and the thing pops up in notification bar blank sd card and in sd and phone storage it says mount it but doesnt work
Well if you have tried more than one, formatted and all, and it still doesn't work I would say that your card slot has obviously stopped working. There is no way to unroot without access to the SD card AFAIK.
well that just sucks guess im gonna have to break this thing to make an insurance claim there goes 90 bucks downt he effn drain
Before you take your phone back to Verizon, try connecting to the phone with adb. If you can cd to the sd card and ls the contents, you can push the RUU to the card and return to stock. I am currently trying to resolve the same problem where the SD card fails to mount on PC and suspect it might be related to root. I might end up returning it to stock to test my hypothesis if I can't find a solution in a few minutes; I'll post back with my results.
Okay, this may or may not be relevant to the original poster, but after more investigation, it appears that this issue might be related to some corruption of system files related to handshaking with Windows in Drive mode that occurred since rooting the device. Restoring the rooted system image resolved the problem. The issue was unrelated to kernels, though, since flashing the default kernel did not improve anything.
If you can access the SD card with ADB, your best bet is to restore your rooted stock backup or re-flash the stock image to see if that corrects your issues prior to returning your phone.

If the phone can't read the SD card it doesn't matter what he can get on it, the phone has to be able to read the sd card to flash anything.
If you have the proper images, they can be flashed using fastboot, which doesn't require an SD card.

Help! Damaged (internal?) SD card

I installed MIUI on my girlfriend's fascinate last night and this morning she's just told me her phone has a notification for a damaged SD card... I told her to try unmounting/removing it and the problem persists making me believe it's the internal card.
Can anyone point me in the correct direction to fix this? I'd like to recover as many of the files from the phone before wiping it if possible.
Thanks!
First thing you should do to confirm whether it's internal or not is to just try swapping the MicroSD with another. I really don't know for sure, but I don't think it would tell you that you have a damaged SD card if it's talking about the internal storage.
Do you have a card reader for your PC? Plug it into that and see if it works. If it detects it, try running a chkdsk on it. If something got corrupted on it somehow, that should take care of it. You shouldn't have to format it.
She's currently at her family's house (we're in college... don't live on our own ) but I'll try that later. She tried putting her microSD in her brother's phone and both phones displayed a damaged memory card notification, which makes me think it may be both.
Also, she's got cwm red, not orange. Could that be the issue? If so, how do I switch to orange?

If the same MicroSD gave a damaged message in another phone, it's almost certainly the MicroSD.
I know there's some issue with Gingerbread ROMs corrupting SD cards. I thought it didn't apply to CM7 or MIUI, but I'm not totally sure. CWM shouldn't have anything to do with it, though. It's odd that she has red CWM, though. How does she enter recovery?
I'd expect chkdsk to handle it. Once you've got access to it and a PC, open the command prompt, and try "chkdsk x: /f /x", where x is the drive letter for the card.
I would think you could just look at the SD card & phone storage section in Settings. Damaged memory card usually appears as not present.
The SD doesn't show up in the mounts and storage, yes. Any idea how to recover those files?
Does the internal memory show up?
From my experience, once it's corrupted it can't be used again. There are several programs that may help you recover files on the card but you probably will not be able to use the card again unless you can get it formatted on something else, ie camera.

If you have a card reader on a PC there's a program called Recuva that may be able to recover pics, video, etc.
try formatting it

[Q] Media Scanner causing phone to continually reboot?

A weird issue manifested on my phone today ... the phone started, upon boot up, to spontaneously reboot. It would boot up within 30s, at which point I unlock it an pulldown the notifications screen (to see what was going on).
I saw several instances of "media scanner running" occurring - over the course of various trials I would see the following messages alternate on the top status bar.
Media scanner running... (system storage)
Media scanner running... (SD card)
Media scanner running.... (USB storage)
Media scanning completed​
...while below in the notification areas I'd see the "Media scanning", "Media scanning...USB storage" etc messages periodically appear.
The phone would first lockup, then reboot perhaps 3 out of every 4 startups. Several of those times the last message I saw prior to the lockup was Media scanner running.... (USB storage).
I pulled out the 32FB Sandisk SD card, then tried booting the phone several times, and this time no issue - booted up fine, no lockups nor auto-reboots. Note though that I've had the SD card installed for over a week, and the problem only cropped up today.
There were two SD card-related changes I'd made last night: 1) used ES File Explorer to cut/paste ~400MB of video from the onboard camera storage to the SD card and 2) copied 1.75GB of MP3 files to the SD card.
The MP3s I had copied to /media/music (direct from laptop to SD, using a microSD-to-USB adapter), while the videos (MP4s, created by GS2 camera app) were moved by ES File Explorer to /DCIM/Camera.
So at the moment my phone is working fine (4 clean boots), though sans SD card - any ideas why "media scanner" may be choking upon scanning the SD card? Should I move the SD content to a different directory, or just kill media scanner?
I've seen issues like that but usually with no name low quality SD cards, with them either bad or modified to register as larger.
I'd backup what you have on the card and format it using the phone. If it's still giving you issues try it on a computer and download a program to check the memory sectors to make sure there are no read write errors.
A good free one is ariolic diskscanner. Can't remember if it can scan SD cards though, though I'd be a little surprised if it couldn't.
You don't want to disable media scanner, not even sure if that's possible. Many things require it to be working.
Sent from my SAMSUNG-SGH-I777 using XDA App
thanks for the tip - I mounted the SD on my PC and backed everything up, then tried deleting the ~2GB Media directory ... no dice, still locked/booted on the first boot up. Going to next clear the other large diretory (DCIM) and see what happends, and then finally reformat the card entirely. Will report back...
so i wiped and formatted the card in the phone ... rebooted several times with the newly empty card, and so far the lock/boot issue hasn't recurred.
Copying all files save the media stuff onto the card, will repeat the test; and then finally will put the media back and see how things go; will report back.
Good deal. Hope that's the last time it gives you trouble.

This is so weird. I've had this problem as of yesterday.
I'm having the exact same issue... but with a Galaxy S 4G.
I tried re-flashing my phone but I realized it was the SD card causing the problem because the internal phone storage scans just fine.
I've tried 2 different SD cards (one Samsung, one Kingston) - backed up my files on my Mac and tried formatting both cards, putting the files back on the SD cards and booted the phone.
Same problem was happening.
The phone boots up fine without the SD card but I am at loss what to do considering most of the apps I use need the SD card to run.
Try formatting them using the phone.
Could be a corrupted file on your SD card. If after the format the phone works fine, put the files back on one at a time and see if that's what's messing it up.
Try also changing the format type. Seems androids like fat32 a little better.

so far so good ... went a day w/o any spontaneous reboots, thought I do want to do a few more startup trials, but fwiw, formatting the SD card (in the phone) seems to have done the trick.
I do realize now that when I first inserted the card in the phone, I just started using it, I didn't bother formatting it - doh!

I have this same issue -- when my MiscroSD card is in, and it goes to media scan, the phone just keeps resetting... SO annoying
question: how do I format the external SD ?

Same problem on Samsung Galaxy Ace
I'm experiencing the exactly same problem on my rooted Samsung Galaxy Ace (Gingerbread 2.3.6).
Reboots with SD card mounted and working fine with SD card unmounted.
I'm using Link2SD with a 2nd ext2 partition, and when SD card is unmounted, all Linked apps work perfectly fine.
I've tried removing and re-inserting SD card and also recreating mount scripts to no use.
What might be the possible causes of this problem???:crying:
Please help :fingers-crossed:

External SD Card No Longer Recognized

So basically what happened is I rebooted my phone, and then opened up my music app, and it said that my external SD card folder (where I keep all my music) was missing or unreadable. I checked my file explorer to see what was going on, and I opened up the external SD folder to find that it was empty. I know for a fact that all my files are there, since everything was working fine until I rebooted my phone. This happened once before, and I solved it by plugging the card into my computer and formatting it from there. I could do that again but is there a way to fix the problem altogether? It's annoying to have to format the card every time I reboot my phone.
My phone's not rooted or anything. 100% stock.
Thanks
Use RECUVA to recover any files back up data and factory reset format phone FAT 32 in Windows .
jje
Okay, I'll try that. Thanks
I factory reset my phone this afternoon and for some reason it's still not detecting my card. I tried the card with my brother's S3 and it worked perfectly fine. Is there anyway else that I might be able to fix it??
EDIT: Never mind, I somehow managed to fix it

[Q] help with vold.fstab restoration

so im currently using a samsung i5510m on android 2.2.2. recently i rooted my phone so i could switch my external SD card as internal since the phone only carries around 150mb of data. so, after rooting the device i edited my vold.fstab file the way i saw on one of the posts on xda. all was well until i rebooted my device, after which it refused to recognize SD card. just to be sure that the card didn't get corrupted i used a card reader and plugged it into my PC, it loaded up with the files. i thought it could be fixed if i formatted the card and so i did.however it didn't fix the problem and neither did factory reseting the device. Ive tried adb commands but its all been useless since the it cannot access the card and neither the phone itself. Ive tried using my other SD cards too but the result is the same.
any help guys? how can i restore the vold.fstab to the way it was since i think thats the problem here?
thanks in advance
