SD Card constantly remounts as being "read-only"

It's has really been the pain in the arse. Really.
I use Lord's Ice Cold Sandwich. This happens occasionally, when I tried to download SD data for a game, the SD card remounts as being read-only.
I tried full-wipe flash, format SD card with Disk Utility of Ubuntu, then reflash it with Android's utility. I tried unmounting sdcard in CWM. I tried fix permission option in CWM. Nothing helps so far.
Thanks in advance!!! :angel:

There's an app on the Play Shop which claims to fix this, give it a try

I actually tried that. The other day I backed up stuff than formatted the thing with Disk Utility tool of Ubuntu. I then went extreme, formatted it again on Android.
I guess the app above might help. The thing is I'm still under 18 for a credit card, hence gotta wait another year to be eligible.... mannnnn
Apparently, the SD card is still in R/W mode, it isn't til I start download data for games, download music, use dolphin... that it becomes read only. The process usually goes for half the bar, than stop.

Should I repartition the SD card with swap storage and ext4 and stuff?

Just format the card with 4ext then reflash rom.

Are you able to flash your SD card? If you are having the same files after the formatting which you had then I don't think anything will work rather than replacing your SD card

[GUIDE] How to format 64 GB microSD to FAT32 WITHOUT sd card reader.

I've recently figured out how to do this and it's pretty simple, but since there isn't a thread like this one yet, I might as well post a tutorial on how to do it and be of assistance to those of you who haven't figured it out yet.
1. Download and install the latest version of the app 'SGS3 Easy UMS'.
http://forum.xda-developers.com/showthread.php?t=1711009
2. Download and install the free 'EaseUS Partition Master 9.1.1 Home Edition'.
http://download.cnet.com/EaseUS-Partition-Master-Home-Edition/3000-2248_4-10863346.html
3. Plug your phone into your computer with the SD card inside. Make sure the computer can recognize the phone is in MTP mode.
4. Open SGS3 Easy UMS and press 'UMS mode'. Your external SD card will now be recognized as a removable disk.
5. Open EaseUS Partition Master, select the removable disk and press 'Format'. Choose FAT32 as file system. Finally, press 'Apply'. Your SD has now been formatted to FAT32.
6. Go back to SGS3 Easy UMS and select 'Mount card'. Unplug the phone.
7. Restart your phone.
8. Enjoy!
PS: To be sure of your succes, you must use EaseUS Partition Master and nothing else. I tried Minitool Partition Wizard at first and it did not work.

I knew this already,
Btw sd card reader is very cheap, everyone has it.
Laptops have it inbuilt

Thanks. Good guide. Sometimes I just cannot find a card reader when I need it. This should solved my problem

Hey thanks. I'm going to give this a try as I have tried and failed formatting my card as a FAT32 that is workable with UMS mode it would work but never ever mount with the mass storage app. You're sure it mounts in mass storage mode right?

Nice guide, but only necessary if you're one of the ones having trouble with your card on exFAT formatting.

I spent hours doing searches on XDA trying to find an app or other method since my sd card reader didn't want to work and then I came across this guide.
Absolutely amazing.
Thanks.

welll my microsd fried randomly today too (Lexar 32gb class 10) ... tried to do this method because I dont have a microsd reader... well didnt work out too well because it keeps saying "could not find location" to sd 1

I have Sandisk Ultra 64 GB microSDXC Class 10 UHS-1 which is exFAT formatted. The only problem I have is that Clockwork Mod will not mount it in recovery. My work around is to remove and replace the card with my old 32GB one which is FAT32 formatted.
* * * * * Will this procedure allow that (use with in recovery)?
Anyway there is an Amazon Black Friday weekend special for these for $35 delivered (with prime).
there is a warning / cautionary note which reads:
"Reformat into file system other than exFAT may cause instability"

[Q] hudge problem with sd card

Hello. I have a hudge problem with my phone. Somehow it automatically unmounts and remounts my sd card for no reason no matter what rom I use. Sometimes it unmounts my sd card and don't mount for a month. Sometimes it gives damaged sd card error and asks to format it but when I insert my card to tablet and it detects no errors. What could be the problem? Can anyone help me fix this?

Repartition your SD card in recovery

You must clearing ext partition in recovery and format sdcard. + set min cpu fraquancy on 245Mhz.

If it does happen with all roms you've tested, including stock 2.1 then your SD card is propably faulty. You formatted it under Windows?

I can't try stock rom because it says that my recovery is to new. SD card can't be faulty because it is new. I had other sd card earlier but my phone didn't recognized it so I bought new. And i have formatted under Windows.

Which ROM are you using?

Sent from my Acme TB02 using xda app-developers app

Then you have to check different roms and kernels to see under which your SD card works properly. I suggest trying newest AOSP / SDSL or CM 7.2 by Tejas build three.

Maybe is the slot of your SD Card, Why?:
Using every ROM, same device and same problem = device
Used other device and everything ok = the "other" device
So, definitely your slot on your device is bad. Good Luck!

Just delete all partitions and make new (FAT32) with some Live CD if U don't have Linux on PC (for best get gParted Live).
Next put it in Your phone and partition again with CWM 6.0, or just use fat32.
Some customized roms mess up sd card if it has /swap.
Noticed this in some 2.3 custom rom, but don't remember name of it.

SD card won't format

Sup guys. I don't know if this is the right place to post this. But here I go. My 32gb San Disk micro SD card was working fine on my gs3 until I got my s4 and now it seems to be write protected. I can't delete or add anything onto the card. It worked fine on the s3 though. So I Googled a little about this and came across a piece of software, which I downloaded and made use of. But the tool I used to supposedly fix the card actually made it worse. Now the phone can't read it, nor can the PC explore its files (but can detect the device), its like a non allocated partition that just needs formatting. But I have tried windows format utility, SD card formatter, HD low level formatter, and HP USB disk utility software and all of them without success. Please help me as I don't know what else to do.

use cwm recovery to format sdcard. u may need to root ur ph for dat

Yes the galaxy s4 does seam to have issues with sdcards, I myself had corrupt sdcard twice for no apparent reason. Your sdcard will now be in RAW file system and from experience very hard to recover, I've tried dozens of recovery windows apps to fix the partition without success (maybe just didn't try the right app) you can however recover SOME datas on the sdcard but there is no guarrentee how much or what you can successfully recover.
The moral of this story is to ALWAYS backup your data.

Why not just get a card reader and use a PC and partition minitools?
To get your SD card back You may even need to do a LOW LEVEL format. This is very different from a standard format.
Use Google and get a freeware version of a low level format software then repartition USB/flash drive then normal fat32 format.

Sent from my SM-N900 using xda premium

I've never had an issue with class 10 Sandisk 32 and 64GB cards, not in the S3, S4, Note3 or TF700t.... (except once, it got corrupted, I had to format it because I was too lazy to unmount it before ejecting every time... Learned my lesson!)
As for the heating, sounds like media server getting stuck on a corrupt file or a huge folder.
-Hook the card up to a pc, let windows explorer do a search for 0kb files. Under search settings>size, or type 'size:empty' (without the quotes) in the search bar. Delete any 0kb media files. (leave the nomedia, playlists and appfiles alone). Repeat process for the phone storage.
-Put a .nomedia file in every folder not containing music, video or pictures you need. You can copy an existing one from another folder.
-If you have a folder with over 1000 files, split them up or if it's not media, hide it with a nomedia file. (I have one folder with over 18.000 files, Mediaserver turned my phone into a grill trying to process it...)
