[Q] how do i fix an unreadable sd card

i recently flashed thors 1.7 touch recovery and when i rebooted my sd card wouldnt mount so i tried inserting it into my computer and my computer would not recognize my sd card either does anyone know how i can fix this its a 16gb sd card and I'm not trying to spend another 40$ for another one but I am thinking this one is toast.....any help would be greatly appreciated!!!!!!!!

As far as I know, there is no way to recover them. Once they are dead, they are gone. You can find the 16gb ones now for under $20 though.

yea i thought so thanks man

You could try reformatting it. If that doesn't work, it's most likely dead.

if its a cheap card you might be lost.. i buy pny cards they have a lifetime warranty.. I Think the reason they do this is because i have NEVER EVER had a bad one from them. They are a cheaper memory provider that is often over looked for there superior quality.. Of course some other brands are backed just as well..
If your tab phone or computer will not read it . well i do not think anyone can help you.

Try Reformatting it through CWM recovery, then see if it mounts.

I don't know if that will work cause when I have it in my tablet and I go to install flash from zip there is nothing to choose from but I can give it a go but I doubt it will work I'll post back and let you know

Try this formatter with uSD to SD adapter.

I have been able to recover photos from a corrupted SD card using the free version of this tool from Zero Assumption Recovery. Worth a try before you reformat.

My SD card was corrupted recently after my phone rebooted. All my photos and important data were recovered successfully after using TestDisk (developed by Christophe Grenier).
After recovering my files onto my laptop, I reformatted the SD card. I did it because the recovery process undeleted useless files.
Just do a Wiki search for TestDisk.
Note: As I am a newbie I'm not permitted to post the link.

I've never ever had such a bad experience but I really don't think that the card is dead unless you pushed it hard and crack the chip.If you use a windows PC ,once you plug the card (make sure it is properly placed into the micro sd adapter) then nothing happens ,as you say (it could be auto mount turned off ) press the windows key + R and type diskmgmt.msc.
This will open the disk manager of windows OS and you will be able to see all attached devices e,g HDD partitions ,USB thumb drives ,sd card and so on.If it s still not visible try to plug the card reader into another USB port.As a rule windows always informs you once you plug any USB device.If the device is not responding it gives an error
good luck.

Not always true... I had an sd card that just died... Neither Android, linux or windows pc recognised it... Windows recognised the sd card reader was attached but "was empty, attach an sd card"... 16Gb card to be tossed...

If the card is truly unmountable/unreadable and you really need to get data off of it, you could also try the service at recoverfab.com . They start where most free data rescue and formatting software can no longer help.

You may recover data from corrupted SD card with special recovery tool, see this useful guide: corrupted sd card data recovery
hope this helps.

recoverfab.com
Hi,
I tried using all kinds of different zero assumption recovery software and sd card repair software but with no look. I thought I wouldn't be able to retrieve any of the pictures I had on my sd card. That is until I found a company called recoverfab.com, they've been able to restore the majority of the files I thought I'd lost forever. I would certainly recommend them to anyone who desperately needs files recovering from an sd card.

My SD Card had the same problem and this, all of a sudden it was unreadable! I tried every method under the sun including trying to access it through an arduino and using SPI which is the alternative way of communicating with the device. I found a company called RecoverFab who said they could read the data from the memory chip even if the erst of the card was dead! So in a last ditch attempt I sent it over to them and the day after they received it I got an email and they had recovered 100% of everything on the SD card! I have never been so happy as it was all the photos from my girlfriends 21st! Superb communication and service!

[Q] Phone Storage not mounted? SD Card not reading?

Hi i would like to ask to fellow seniors and developers of xda,
Why does my phone says phone storage is not mounted? I tried everything from factory data reset to the PHV ( Power + Home + Volume Up ) buttons. And it seems nothing is working. I have been looking for answers for days. And i dont think anyone has this problem than me. Im the only one with the problem. SD Card is not reading as well. I tried my SD Card on my wife's SM-N900 ( same as mine ) and it work well. Nothing happened. Is there any solution to this? Please help me solve this issue. Thank you for your time. /;

It might be a hardware problem specific to your phone - a bad contact or something similar. Test with 2-3 different micro-SD cards that all are (recently) tested and working fine in other phones.

Yes it worked well on other phone's via alcatel. So it means that there's something wrong with my hardware right ? How do i change the firmware? Maybe something went wrong with its firmware? It has never fell before since its brand new..

My note 3 was doing fine and for past few days suddenly the sd card is not getting recognised and am not able to find which application got updated latest to cause this problem. Please suggest me the solution to this.
I did the card formatting as well factory reset the phone. Still the phone gives message as Blank SD card.

Hi suddenly the SD card starts functioning and today it goes on and off means, sometimes it reads by itself and other time it gives blank sd card.
My note 3 is not rooted and Samsung guys informed that warranty ceases with rooting.
Can I have other workaround without rooting.
Thanks a lot for the support.

Apps disappear after reboot?

I have a strange problem with my note3 n9005 that is running omega v.16
Lately when I install an app from play store it works great until I reboot the device.. After I reboot the app I just installed is gone and I have to install it again..
My old apps that I have installed before this problem started occurring are just fine, and does not disappear after a reboot.
Does anyone know why this is happening, and if there is a way to fix it?

I just checked, and you where right.. Some apps seems to automatically install on the external SD card, I moved it to device storage and it was still there after a reboot..
Many thanks my friend.
Now that leads me to my next question..
Sense many apps are installed to external SD and seems to work just fine even after a reboot, why doesn't any new apps stay there anymore?
I don't remember changing anything..
Is there a way to make it work again?
Thanks again

To be honest with you I'm not sure. I do know android has made some changes in KitKat in regards to the external SD card not being able to write/read for 3rd party apps. There was a fix for this somewhere on XDA. Now the question is, if this is related? Couldn't tell you. Only advice I can give is, leave your apps installed in your internal memory. Keep everything else for your external SD. Glad I could help!!

Yo. I may shed some light in this situation.
Get a new external SD card - 'tis what I did.
I had this 64GB SanDisk UHS-1 Class 10 - exactly what you have: http://www.sandisk.com/products/memory-cards/microsd/ultra-class10-for-android/
One day when I took out my MicroSD from my phone and put it back in. I thought everything was fine. During transfer it transferred things to my computer, but then it kept freezing up. My ROM file (250mb) was transferred somehow into my MicroSD along with the Google Apps zip. When I turned off my phone, preparing the ROM flash, I only saw my ROM file and not my Google Apps file. I thought "that was strange" and I did it again, by deleting both files just in case of MD5 mismatch. This time both files confirmed inside the MicroSD, I rebooted. No Gapps showed but my ROM showed, so I tried to install it (note I deleted this file already) and it said ERROR. I plugged it back into my computer, Google Apps was not there, but my other files like photos, music, app data still remained. One peculiar file popped up, was my ROM file. It was 20kb. I deleted it. Rebooted my phone, plugged it in. It appeared again.
Seems like my microSD entered a stage of read-only but it isn't actually read-only. Like it doesn't retain any information AT ALL. My MicroSD can't be touched, I tried deleting 13gb. Windows showed the data actually getting deleted with the bar (and it fluctuates in data I/O speeds!). Unplugged. Rebooted. Plugged back in. 13gb worth of files still there, in tact. Like a visual storage to fool people you can delete files but in fact you can't.
I tried it on my Note 1 (FAIL), Note 3 (FAIL). The only way I could read the extSD was to plug it in a microSD adapter and transfer files out of it. At least Sandisk thought of a failsafe read-only phase to back up files. Instead of breaking down completely.

You are absolutely right.. I checked the card buy putting it in my computer, and it was as you said in a read only state..
I was able to copy my things from the card, but I could not put anything on it.. I could not even delete anything or format it!
So I went to the store where I purchased it, and now I have a brand new Samsung UHS-I 64 GB.. Hopefully this one will last me longer.
Buy the way, it turned out that I purchased the card on July 17 last year, so had I been waiting for just 6 more days, I would not have been able to have it replaced.. So I owe you many thanks.

[Q] SD Card blank or has unsupported filesystem

Hello guys,
I have a Galaxy S5 G900T running the AllianceRom 3.1 made for G900F. I use an external SD Card SanDisk 16GB and since yesterday I never had a problem.
So, now I'm experiencing this error: "SD Card blank or has unsupported filesystem" on Notification Panel. When I click on it, android asks me if I want to format the card, I click OK, and at the end the same problem occurs.
Things I already tried to do:
1) I tested the SD Card into another Galaxy S5 and it's running OK without the problem;
2) I formatted the SD card (full format) on a windows computer. Windows recognizes it, and it's running OK;
3) I checked the file vold.fstab on /etc folder and it has the same content as another Galaxy S5 that is running OK the SD card;
4) I re-flashed the AllianceRom 3.1;
[EDIT 1]
5) Tried to wipe the SD Card using TWRP Recovery (as image 1 attached)
6) Tried to partitioning using TWRP Recovery (as image 2 attached)
[EDIT 2]
7) I bought another SD Card, a Samsung 64GB and when I insert it on device I don't get this error, but also not able to mount, it doesn't even recognizes the SD card.
p.s. I searched a lot on XDA, even on Google, and those was the possible solutions I've found, but didn't work for me.
Does someone experienced this problem and was able to fix?
Does anyone knows another alternative that could work?
Thanks in advance

Copy the content of the sdcard to the pc and format the card on the phone itself, that should fix the issue.

Have you tried another SD card in your phone? EDIT: Nevermind this bit
When you plug the SD card into your handset (do it while it's off) Does the SD Storage show anything?
You could try formatting it in another handset if you have the chance then try plugging it in.
Are you using stock Sammy firmware? Or have you installed a custom kernel? Could be one of those playing havoc with your device if so, back up and revert to stock if you can, retest the SD in there.
Test to see if you can retrieve data from the SD card, i've found that although SD cards show up in windows, when I attempt to copy data to the PC it fails, when I say fail I mean it stops progressing and doesn't copy, particular files appear corrupt.
You could also do a chkdsk /f /r via windows on the SD card, or even a general error check.
chances are one of these things will be the culprit, if none and it's still working in another phone and other cards are working in your device then i'm stumped.
Good luck

I would try philz recovery, i had all kinds of problems with twrp on my note 3 and s5 until switching. Not knocking twrp this is just my experience

I formatted my device right now and installed Samsung stock firmware with stock kernel. I also tried to get back to stock recovery, then installed CWM and TWRP, but the same problem
I'm starting to think this is a hardware problem, because I tried everything and nothing happened.

Quite an odd one that, i'm a little stumped.
did you try error checking on windows? OR even a format in a different handset? OR a different card in your phone to see if to see if it reads?
On the other hand if the phone isn't that old, return it, 28 day swap should be good if you're in time, otherwise it's back to sammy.
sorry I can't be of more help m8.

Same problem with GalaxyS5 and 64 GB card
I am having the same issue with a 64GB memory card in the Galazy S5. Blank or unsupported file system.... doesn't format in phone. works great on PC and even on old Motorola Razr phone, format exFAT and FAT32 tried but the phone doesn't care.

Same problem with GalaxyS5 and 64 GB card
Have you found a solution to the OP?
I have an S5 too and it's doing exactly the same. I tried a 64GB Sandisk and Samsung cards, both work flawlessly in PC, MAC and even a different phone. WTH???? My 32GB Sandisk works well in the GAlaxy S5 too, I am about to see if it blends....

Hello guys,
I have a Galaxy S5 G900T running the AllianceRom 3.1 made for G900F. I use an external SD Card SanDisk 16GB and since yesterday I never had a problem.
So, now I'm experiencing this error: "SD Card blank or has unsupported filesystem" on Notification Panel. When I click on it, android asks me if I want to format the card, I click OK, and at the end the same problem occurs.
Things I already tried to do:
1) I tested the SD Card into another Galaxy S5 and it's running OK without the problem;
2) I formatted the SD card (full format) on a windows computer. Windows recognizes it, and it's running OK;
3) I checked the file vold.fstab on /etc folder and it has the same content as another Galaxy S5 that is running OK the SD card;
4) I re-flashed the AllianceRom 3.1;
[EDIT 1]
5) Tried to wipe the SD Card using TWRP Recovery (as image 1 attached)
6) Tried to partitioning using TWRP Recovery (as image 2 attached)
[EDIT 2]
7) I bought another SD Card, a Samsung 64GB and when I insert it on device I don't get this error, but also not able to mount, it doesn't even recognizes the SD card.
p.s. I searched a lot on XDA, even on Google, and those was the possible solutions I've found, but didn't work for me.
Does someone experienced this problem and was able to fix?
Does anyone knows another alternative that could work?
Thanks in advance

Same here. My phone already went in for repair for this and the front camera ring falling issue. Mine was preordered and shipped at launch. It worked a few weeks and now has stopped again. Simply won't recognize any SD cards. I tried an old 2GB, a Kingston 16GB, a Lexar 32GB from my GoPro, and a Sandisk 64GB. All cards work elsewhere, but my S5 never indicates anything is inserted. This is my first Samsung, and it might be my last. I never experienced issues like this on an HTC.

Any progress here? I just got a sweet 64g card Samsung because my others have worked well BUT...
S5 Blank SD card of death. ....

[Q] Micro Sd Issues.

So i recently Updated to NK2 and everything was just normal, until lately i kept on trying to save a pic or an Mp3 on my sd card with no success, so i decided to format itto see if the issue would go away.
To my surprise i tried to format it and it wont let me, i tried on my phone , on my Pc, on a ubuntu Pc and it would say "format successfu!" yet I would insert the sd card on my phone and everything was still there!.
i dont know what else to try!.
it wont let me save, erase or ,format the Micro sd!.
Any help is greatly appreciated!
Thanks.
P.s.: It's a "SanDisk Ultra 64 GB microSDXC Class 10 UHS-1"

Have you tried formatting as root? There could bave been some weird permissions fluke that happened. Is your device rooted? You need root to enable being able to write to the sd card yourself from the phone, otherwise only apps can if i understand it correctly.

yeah I'm rooted and all.
The case is that my Micro sd card happens to be a bad batch of cards which I recently found.
I was researching on it and this card happens to lock itself, apparently there is no way to unlock it, according to Sandisk.
so I contacted Sandisk and see if I can excange it (Hopefully, I am Still under warranty) otherwise I'm stock with a card full of music and pictures I no Longer want, and that it wont save any other files , until i buy myself a new one.
thanks thought!

Sandisk cards have lifetime warranties as long as you have proof of purchase your good to go. I exchanged mine with no issues but I ended up getting a 64gig Samsung card.
