Sd card not detected

Hi everyone
I have a problem with my Sd card not properly being seen by any Rom at the moment. I noticed it when I flashed the new virtuous sense 4 Rom, as I couldn't view any of my pictures in the gallery and also no music can be found in any music app.
I decided to return to my backed up Rom which was runny suprise and the same problem occurred even though I had no issues before back up. I also tried a couple of others too.
I always full wipe between roms and just wondered why this has happened, have I pressed something in recovery or is my Sd card faulty? I can view my old photos by using my file explorer and selecting view with gallery and also listen to music this way also by using the native music player.
Any advice would be handy before I buy a new Sd card and start all over again.
In settings/storage it still tells me how much space I have on the Sd card so I'm not sure what's happend.
Hope someone can help. Thanks in advance.

I posted a solution for this in another thread, it seems that this is a repeated question.
For those of you that encounter problems of having trouble finding your gallery and music, but yet those files are still in you SD card
Follow instructions below:
1. Plug your phone to your PC
2. Use the search function on your PC and search your SD card for ".nomedia"
3. Delete all
4. Reboot your phone
TADA!!!

Hi
Thanks for the info but didn't help. I searched and deleted all .nomedia files then reboot but no luck

Heck, I don't know. Did you make a backup of your whole sd card, format it, then transfer everything back?
Are there any .nomedia files in the sd card?

SanDisk 16GB microSDHC Memory Card Ultra Class 10 UHS-I with microSD Adapter
Hello mates, greetings from Turkey.
i bought the following sd card and start using it in my i8150. However phone freezes / thinks a lot almost everytime when it starts using this SD i.e. during startup, previewing gallery, etc.
is this a known issue or something fixable?
here is the link of my new SD.

for an exact solution, i formatted everything (phone, internal sd, external sd by following the "go pristine" procedure).
then put the new update zip files to re-install the rom, open the phone in CWM mod.
CWM saw the contents of the ext.sd and i started installing zip file.
CWM was saying that it is installing the zip, however it was doing nothing as there were no further progress of installation.
at that point i figured out that my phone and my new sdhc class 10 ext.sd card are not able to communicate in a healthy way.
card is working in laptop, but has trouble working in the phone. most probably card was corrupted at the first stage while i am buying iti from store.
so i am giving up this.
just fyi.

Hi,
here is what i did last hour.
formatted again in "default" format and tried to re-install rom from ext.sd.
During first attempt, attached screen does not changed for 30 minutes, so i gave up again and force to shut down the phone by pressing down power button for 8 seconds.
I thought the phone will shut down only, but it restared in CWM mode. Then i gave another try and this time phone processed the zip file.
so far no new problems but let you know in case of one.

use that Rom RemICS 1.7
and here it's the Link: http://d-h.st/xwI

How was this solved?

something similar happened to me with mine. I had to reformat it and I lost everything that was on it but it works now.

Same Issue
I has been dealing with this issue ...now with two SanDisk Micro sd cards XC I, I did tried to format in almost all the know ways...tried Linux, Windows, command line, Different adapters, Different computers, tried with the Storage feature from the Android OS,
Now I have two beatiful 64G micro sd cards....READ ONLY. Also if you browse the content in the file explorer from the computer the Delete option is not listed in the explorer.
Is there any magic tool that can remove this read only feature from the cards????????

Same issue here: did you update ROM to 4.3 version? I read that it could contain a setting within the platform.xml file that you find into system/etc/permission folder. See this
I tried it but with no success.
I hope you're luckier

Btw i sent it back to Amazon asking for refund (and they agreed). Bye

I warn you trying this setting. I tried this >>> Editing .XML file. I started getting severe force closes especially Google Frame Work Services. Even reverting did not help. Had to use my Nandroid Backup to go back.
4.3 is sucking so far for 64 GB External SD Card write support. Titanium Backup & Helium both apps can not do automatic scheduled Backups on External SD Card since 99% of the time they do not get Write Access. Only way to do an external SD Card backup is manually after rebooting the phone, even that is hit n miss.

I agree with you. 4.3 is still far from 64Gb SD Card support, and I know that editing this file can be dangerous, but I read that someone was able to restore his card and due to its cost was worth a try. During my tentative, this update didn't have effect (but at least I didn't get more troubles).

Same issue.
64GB SanDisk card from my Note 3 (search brought me here) became read only after 5 months.
I've ended up sending it under warranty back to SanDisk.
I'm glad I didn't loose anything as I've backed it up but still don't like the idea of returning something with a lot of my data and photos I can't delete.

may have found solution

I was having the very same problem. I finally went into the computer management, and was about to throw phone across room....when I tried to format one last time. This time I unchecked the quick format. It is taking longer, but seems to be working...I am keeping fingers crossed.
Full Format has finished and card is saved! Hope this helps anyone in the future.

[Q] Running out of Space, Symlinks and Installing Apps to SDcard

Due to size limitations (GPads only coming in 16gb varieties) I am beginning to run low on space on my Gpad (v500 running cm11). However I have a 64gb microSD card and I would like to use this as much as I can to conserve space on the internal memory.
There are a few ways to solve this but I not fully know how to do this.
Firstly, is it possible install apps to microSD card? If so, how? I know some devices support this and some do not. My phone for example does not but I have heard that some people have had success with this.
Next, there are some rather large folders on my internal storage that I would like move to my sdcard however the apps that use those folder can only read them where they are currently located (cmupdates, ebooks, etc).
I read about symlinks and managed to make a few but the only place I was able to make a symlink was to /data/media/0. But the changes to that do not show up the apps which I believe read either /sdcard or /storage/emulated/0. And for my SDcard I can get to it either in /mnt/media/sdcard1 or through /storage/sdcard1.
I tried and succeeded in making a link between /mnt/media/sdcard1/eBooks and /data/media/0/eBooks however the link does not show up in /sdcard or /storage/emulated/0 and it does not show up in the apps, leading me to believe that is where the apps read the sdcard from.
If anyone can answer the above two questions or give any other suggestions for maximizing available space on my internal card please let me know.
Thank you!

I think most of your issues could be resolved with Link2SD (under 10 posts, can't post a link to Google Play).

You can also use an app called Foldermount. It's only $.99 ( if I recall correctly) for the unlocked version. This allows you to move any folder to SD card. I like it as it guides you thru the way and will move the data for you as well. Latest version has been updated to allow apps from play store to install properly. Well worth the $1 price.

Thanks guys! Looks like using these two combined I can get exactly what I wanted. I'll use link2SD to put apps on the SD card and Foldermount to move the other folders I want moved.
Thanks again!

Can you let me know if this works for you? I can't get mine to read or write my SD card at all! I can't even move a picture from my Box cloud account to the SD card. Are you experiencing this? Or did I get a bad unit?

These solutions did work for me, I am still tweaking to get it the way I like it especially since every time I update my Rom Link2SD has to generate new scripts.

I've tried 2 different SD cards both of which I can move files to and from on my computer. So I know it's not the card. I'm thinking maybe I should exchange it out for another day one...

Probably... That sounds like a device issue not card.

How are the cards formatted?
The ROM you are using may not support the format.

Well, if you did it from your PC, it may be formatted NTFS, and you need them formatted FAT 32. Get it here; http://www.partitionwizard.com/free-partition-manager.html Not only allows formatting almost any format xFAT, Fat32, NTFS, etc.. and you can partition them also which is not supported by Windows, but IS supported by most Android ROMs. I doubt there is anything wrong with your device.

I have been trying to fix the issue with Rom updates and link2sd. You have to provide the Rom (in my case cyanogenmod) a backup script so it can back up the files. I am planning on figuring it out at some point but if you get it before I do would you mind posting your script? Thanks!

So a follow up with this, I was able to get a script working. I don't know if this feature is unique to cyanogenmod or not but any script in /system/addon.d will execute itself during a rom install and be restored automatically if it was wiped. So using 50-cm.sh as an example I made a script called 11-link2sd.sh to perform the backup of the mount script for link2sd which is located in /system/etc/init.d/11link2sd.
I then had insert this script and my mount script into a cyanogenmod update and flash it in. But after that I tried flashing an update of cm11 to test it and it worked! Attached is my script which should also work for anyone who is able to flash it into their /system/addon.d folder.

[Q] External SD Card Read-Only Problem

I tried researching this but wasn't successful finding same exact problem or solution. I'm on 4.4.2 Baseband N900TUVUCNB4 rooted with stock rom and ext sd fix. Everything was working fine until recently. My external SD card has inexplicably become read-only, both on the phone and on my desktop. I first noticed this last week when the phone camera began having problems writing to external SD card, and now I can't sync music to card. I've tried formatting on the phone and desktop, both quick and full but no dice. On the phone, I am able to delete individual files or folders but they reappear. On the PC, I can view but get write protect message when trying to format. Anyone else come across this or have suggestions?

Happened with me once with a different phone/OS. Weird thing is that it was only for a particular SD card. I put a different card and it worked.
It turned out to be a problem with the card (dunno how thats possible though).

What's the brand of your SD card?

I have the exact same problem with my SGNote 2 and SanDisk 64gb micro SD card. First I lost some pics I have taken that day. I searched through with a file rescue tool but they were nowhere to be found. Deleted files reappear, and the ones I copied from internal SD dissappear.

It's a SanDisk 64gb class 10.

Glad to hear I'm not the only one. Maybe we can share the solution when we find one. I'm using internal memory in the meantime for new media files, but frustrated that I am not able to use the rest of the memory available on my card.

SanDisk works fine for me, maybe your sd card is a faulty one, let's wait for a while here and maybe someone could answer your question and hopefully solve your problem

Thanks, Lorettaa. It seems like that's the only option right now, since I can't find any other info about it on XDA. I know Kit Kat has that design "flaw" where apps can't write to an SD card, but I can't even write to it, modify it or reformat it on a PC. I have full read access to every file, just can't do anything else

I have the exact same problem, i tried many options , used some softwares in windows to format , wipe, fix, modify. nothing works.
One possible reason for this problem is file system errors , which can be rectified using the 'error checking' option in windows and 'fixing the file system errors'
But that doesnt solve my problem, even after formatting using advanced softwares, the sd card is the same - no files deleted, no files added...
The fat as well as ext4 parition is not formattable now in anyway.so the possible conclusion is 'sd card is going to fail'.. Take a backup before you loose the read capability.

Recuva is a good, free tool (from the people that make CCleaner) to deleted recover photos.

And one possible reason for a false error condition is a corrupt system. This is normally an unlikely possibility but it is very likely on devices that have had partition images written to (i.e. a flashed ROM). If you have done all you can to the SD card and if the errors are not only on one SD card then wipe everything and load a backup. If you still get errors then wipe everything and revert to stock to see if they still occur.
