[Q] SD Card Mounted Readonly Problem

Hi,
I keep getting this error - Mounted Readonly.... the sd card has an unexpected problem.
I installed the NextSense 3.0 Rom earlier, it worked fine for a while until i installed some apps to the sd card and then this error kept appearing.
I searched for solutions and every one involved removing apps, especially task killer. I have removed everything and the problem persists. Does anyone know what the problem is?
Failing that i'm going to wipe everything and start again, can anyone tell me how to correctly wipe and repartition everything? The instructions I found to partition are:
"Partition SD" SWAP=0, EXT2=512, FAT32=<remaining>
then "SD:ext2 to ext3"
any advice would be great, thanks!

Not sure it's all that helpful, but I had the same problem with ieftm's Official 2.2 ROM. The problem seemed to go away after I connected via USB to my pc and selected the 'Disk Drive' option on selection type on my Desire. After I disconnected, all was good.

I had this problem also. So i just popped the card in my computer and reformatted it with Gparted (in linux). If you don't use linux, i'm sure you could still format it in windows to fat32, but then you'll need to create an ext partition via the phone.

thanks for the reply, thats what happened when the problem first occured. I had it connected as a disk drive to copy some apps to the sd card and after disconnecting it the error started.
i tried it all again nothing helps

grrr i hate taking it out of the silicon case, incase it goes all saggy.
thanks, i'll give that a try

I also had the problem when I tested ieftm 2.2 rom, I changed to another, using recovery to format and partition the SD card, and everything went back to normal.

Any suggestions... Tried adb shell mount /sdcard and everthing else I've found...

Like i suggesetd before. Take the card out of the phone and plug it into an sdcard reader and format it that way.

I had that issue with some of the OTA ROMs apart from Pinky.
Just connect it to pc in disk drive mode and then remove safely in windows and then select charge only and remove cable. should be fine.

I had the same problem and I repaired it with Windows Vista Tools. Right click in the drive letter, Properties, Tools and Check Disk.
It solved some problems and it worked fine in the phone.
Regards

I had to format my whole card, the Win7 repair function doesn't work for me...

based on my experience, this issue occurs if you don't do reboot after the first boot. so after you install the rom, when it asks you to set the language, reboot your phone again. after that then complete the setup process.

not true
This happened also to me with ieft ROM. I did a few reboots before this happens to me. I tried some workarounds that people say in this thread with no luck. When connecting the phone to the PC, phone did not give me the option to mount the sdcard like disk drive. In the end, I'm formatted sdcard, deleting ext3 partition.
I'm using ap2sd of Froyo with "Mod Install Location" app from market. And this works fine. I have no problems with space in internal memory.

the quickest way i solved this problem was to unmount the micro sd card under the SD & phone storage options then remount it again. thats how i solved it, hope it helps.

Sry, but this function is freezed, it doesn't work. At the moment only repartitioning is working for me. It seems that problem is because of Froyo implementation. Shame

oh well

better make a list of all possible ways to fix this prob i suppose, starting from easiest to hardest.

I have fixed this issue with the wipe of the dalvik cache! Try this!

I had the same issue. Copied everything across from the SD Card to a temp folder on my PC (Win 7 x64) then it came up with a copy error from one android.temp file, I skipped it, copied everything, formatted to FAT32 then copied everything back across and the issue was fixed.
Maybe something had locked that file and corrupted it perhaps?

When it happened to me it was a corrupted app. I had downloaded an app from a site and put it on my card. I don't think it downloaded all the way, and messed it up. But the way I fixed it was moving apps and formatting the card.

SD-Card not Found??

Please help, I tried searching the forums and couldn't find a solution.
I formatted my SD-Card (1GB) on WinMo using the dedicated app, however when I go to boot Android but now it no longer reads my card and am unable to use SD-card dependant apps such as Spotify or Gallery.
What should I do?
I deleted the image file to see if that would work but still the same problem.

Yes, and preferably don't use the built-in Windows way either. There's the HP format tool, and a lot of people have had success using gparted...

i thought that must be the way to be?
since u booted android from microsd. so android thinks that the whole microsd is the system boot. hence its not detected as SD to android.
to fix, nid to create 2 partition on the microsd itself. 1 is ext2 and another is fat32. in this, android should be able to detect the fat32 as SD mount.

sd card not detected on phone or pc

Hey guys,
A friend of mine gave me his desire to root and flash a rom, while I was partitioning the SD card - everything went well (I used a windows app to create the partitions while the desire was plugged in in USB mode.
All went well until I disconnected it after the process was complete - now the phone nor PC detects the card.
What are my options?
Cheers

You're using a usb card reader on your pc or whilst in your phone (plugged in via cable)?

Using a card reader with the microsd adapter

Use gparted in the reader to see what you can see.

Yup. Try that

OK this is unusual, I managed to boot into recovery and mount the SD and sd-ext without any issue - I even booted into a custom rom I flashed from SD, but I still can't get the phone to detect it when booted.

Corrupted fat-32
Sent from my HTC Desire using XDA App

Like rootSU said, try it with GParted in your pc and see if it can find it. If so, format it all and re-partition it.

OK I managed to get it fixed - seemed like an issue with the partition - I used recovery to mount USB storage (it worked) and I re partitioned it and it is now functioning correctly.
Cheers guys and thanks a lot everyone for their inputs !

I used MiniTool Partition Wizard Home Edition ! very nifty app !

You're very lucky, its an awful app. I feel so strongly about it, I even put it in my signature (incase you missed it).
I bet its because you used minitool that it broke in the first place.

wow, that is rather fine print haha, I hadn't seen that there - I too have a feeling it broke cause of the app, but it did manage to fix it - hopefully I won't have to go through this again - if I have to I'll use gparted - Lesson Learnt !

I'll make it bigger

I tried mounting it through the rom -- settings > storage -- there the mount sd card button has no effect and says insert memory card -- then i went into cwm and did unmount /sdcard -- then mount /sdcard -- still it wouldn't show up..

When creating a partition use CWM or put the card in a reader, trying while the card is in the Phone and connected to the PC will give issues.

I tried using the mount and storage > format /sdcard option from CWM as well -- it completed successfully -- but did not work
the sdcard is detected by CWM as I installed the rom and mods through that -- only that once the rom and everything is installed and when I boot into it -- I don't see the sdcard -- says Mount SDcard under -- settings > storage -- and the button is greyed out !!
will deleting all partitions and creating new ones have any effect on it using disk manager in windows ?
ohh and another thing -- when the SDcard is replaced with another one it works on the fone !!

Deleting the partitions is worth a try, I resolved my issue before without a card reader but can't recall exactly what I did, and I got the issue by trying to create one with the Phone connected so just keep trying.

Remove the card and plug it into the converter and plug that into your computer or card
reader then re-format using FAT32 ONLY then put it back in your phone and then your 64gb

Use the Windows drive manager to delete the partition on the MicroSD, do not reformat it with windows, plug it into the phone, and attempt to mount, it should do so but with 0 space now. Format it with the phone. Or look for the tool "fat32format" on the internet (Google is your friend) in order to force a format in FAT32.

Then try exFAT but if you have a windows computer, the default is FAT32.
If that don't work you will need to find a friend or relative who has
a windows computer which you can use to format the card using FAT32.

nope, you cannot install apps on external sd on the s4 yet.
even the apps2sd is not compatible with the S4.

You can have all your mp3's, videos, movies, pictures and documents plus backups of the rom and new roms or other
stuff but you just cannot use it to install apps until one of the devs finds a way to create a compatible app which will allow
for app installation on external sd.
Something similar to the apps2sd app which is not compatible with the S4.
Perhaps the developer of that app will upgrade it making it compatible with our phones.

Google it and look it up,
Ever since windows xp fat32 was always the default when formatting usb flash drives(memory sticks) and sdcards.
Right now I am running windows 8 but I ran all the other prior versions of windows including windows xp.
When formatting hard drives, even external usb hard drives then windows (all versions) default to NTFS.
I never seen any versions of windows operating systems defaulting to exFAT.

Your right actually I got confused its actually partition space anything over 32Gb is out of a normal fat range for windows.

1) Make a LiveUSB stick of Ubuntu.
2) Boot into the USB stick.
3) Use GParted to format to Fat32.

Or you could search for 1 of the thousand formatting utilities that will do it and not have to download a 2gb file.

Do you know if due to the size of the memory card the phone takes a lot more time to load stuff??? I do not want to buy a 64gb if it will slow my phone a lot. If that's the case i may have to buy a 32gb card. Please tell me your input on this.

Well not in that sense but let's say if you would like to play a video or a song you have saved in your 64GB card. Does it still play it right away or have you experienced any slow downs? Someone who i know that works closely with phones informed me that it slows down the phone when loading files such as mp3 files or video files. Thanks dude.
