[Q] SD Card damaged

Hi guys need a little help here..
So my phone froze up earlier today and seemed that it shutdown, so no problem right, battery pull then reboot... Unfortunately, after rebooting after the "preparing sd card" prompt it said "Damaged SD Card" sd card damaged you.may have to reformat it.
Any ideas..??? I'm quite confused too as my sd-ext is mounting fine and I can go ahead and open it via root explorer, and I'm sure it's fine coz I'm able to open apps that I know are on SD.. but what's up with th fat32..? Sadly I don't have any backups.. any workarounds I can try before reformatting everything..? (Not even sure if reformat will do any good, as it is possible that the card itself got corrupt, though hopefully not)
Suggestions are much appreciated. Thanks!!

Alright so HM you are spot on my friend, tried reading it on the PC and loaded just fine, so I ran chkdsk and selected both options, slapped it back on my phone et voila! Good as new! Thanks for the help, I panicked a little and posted this straight away via mobile app, as it got "damaged" while I was in the office and had no means of checking my SD card via PC.. Again many thanks!
Although 1 question comes in mind, what could've caused this? As of course I would definitely want to prevent this from happening in the future.

if you could not reformat it through usual way, try low level format. work on me all the time when my sd card corrupted. but you have u back up first while u still can cuz when its done, kinda hard to get back up the data.

I would also check for a corrupted file somewhere on your SD card. It will be the one that you were working on before the freeze. If you go and try to delete it, surpirise, it won't delete. I had this same problem and ended up just renaming the folder "bug". Tried to move it over to PC and use Unlocker or File Assassin and no luck. Finally ended up pulling everything off the card and reformating completely.
Check you media and any icons that are grey with an ! in there. Easy fix for that is to go into DCIM/ Thunbnails and delete the top two items that aren't actaully thumbnails. Then go to settings and unmount->remount sdcard to initiate the media scanner. This way you don't have to delete the grey! picture to bring it back into good standing and the picture won't be lost.
Chances are that it happened b/c something interupted whatever you were doing and fritzed out the SD card. Maybe run a sd card and sd-ext check in AOR or MZor too.

internal sd card wont mount

I was going to post this in the AOKP rom page but i figured it'd get seen more here and maybe its not even a problem related to the rom. I recently installed the AOKP rom located here http://forum.xda-developers.com/showthread.php?t=1831858. everything was great the first day then i started getting random reboots and losing my data. So I flashed a back up and still got the same problems. I lost my data yesterday, fixed that by manually changing the APN settings and everything was fine other than still getting random reboots. today I went to take a picture and it says "no external storage". I opened root explorer and I can access my EXTERNAL SD card but not the INTERNAL. I tried to mount in via the setting, storage menu and it wont mount. Also tried mounting in CWM recovery, no dice.
Is this a hardware problem or something software related? Anyway to get my stuff back or is it gone? I thought about trying to format it through recovery but how can I do that if it wont mount? Any help would be greatly appreciated.
I'm about to go through and install a "clean" copy of this ROM hopefully. Or I might try another ROM I know works like it should.

Installed a new Rom. Everything works perfect so far but still can't access my internal sd card. Any tricks how to get this back or do I need to just turn it in for warranty?

Warranty may be your best solution, you'll have to revert to stock using kies/odin which may on it's own fix your issue.

Are you also receiving the "Blank USB storage or has unsupported file system" error?
I have been battling this issue for a friend of mine (I own only the I9300) and I believe I have somewhat of a fix. It will allow you to use an external SD card.
If you can use / access the external SD card on your phone then disregard this message.
If you can't access any of the storage, including the external SD card try following this short tutorial I made:

Im still able to use my external sd card. I can read and write to it from both phone and pc.

The internal SD card is essentially part of the motherboard. If it's corrupted, you have no choice but to warranty the phone out. Kishke's right in that restoring to stock might be your last, best chance.

Very Very Very Strange SD Card Problem

My SD card is in one or another way corrupt, I think. The system apps won't read the SD card. It's very strange, because I can browse the whole card on my computer and in ES File Explorer too. The Camera app can store images captured with the device, but not view them ...
I've tried to fix it with flashing ViperS 1.3.5 over my ROM again without wiping to see if there were any corrupted systemfiles, but no. That didn't work. So I mounted the SD card to my PC and backed it up, re-partitionated it and copied the backup back to the SD card. Still, the same problem is there. So I rebooted my phone into Recovery (4ext), tried to fix the permissions from there, and nothing worked. I checked the partition aligment and it showed me that the Fat32 partition was not perfectly aligned. So I deleted all partitions from the SD card using recovery (Fat32 and Ext4) and re-partitionated it from there, both Fat32 and Ext4.
Then, I tested the partition aligment and it showed me that both partitions was perfectly aligned. I rebooted and hoped it should work now, but no.
So this is pretty frustrating. Is the WHOLE SD card corrupt or something? My phone manages to load all my apps from the Ext4 partition, so I don't think that's the problem.
PLEASE!!! HELP!!!!!

The problem seem to have fixed itself ...! It's very strange, because almost every time I'm starting new [Q] Threads, the phone fixes itself... Strange -.- But, can someone tell me what caused the problem if it appears again?

Very strange I'm not sure what the issue was. I know with my SD card it showed corrupt or damaged SD but yet ran perfectly on my card reader.I formatted on my computer but still said damaged card. so I figured I needed to format through recovery yet when I tried to go to recovery it would say SD card needed. So I ended up pulling battery And getting into recovery that way then I was able to format. After I formatted from recovery the card was once more able to be detected and the error message stopped. It is a 64 gig. Maybe somehow your card wasn't formatting correctly. But how it fixed itself is very strange. I know in my case I thought I had a bad or damaged card because it kept saying damaged and was not able to be recognized because it needed to be correctly formatted even though I'd formatted it on the computer before hand. Maybe in your case it was an issue like that? Not sure but glad you got your issue fixed. SD cards can be touchy sometimes. In my case I had to format twice before it was recognised.

Dude, I'm going to get you to post threads about my problems too and see if they miraculously cure!
Maybe you should make a thread about a problem with you bank account because it doesn't have $10,000,000 in it! See if that's suddenly fixed. hahaha
As for the SD Card, did it suddenly work right after a reboot? Anyway I agree with Realsis. You can probably cure this problem for good by formatting the SD card, even if it's working now. Just save the contents to your computer first so you don't lose everything.

"SD Card safe to remove" "Preparing SD card" over and over again.

Hi fellows, sorry to bother you i always try to manage to solve all problems on my own (researching) but there no info on the subject.
A bit of history: im the happy owner of an MT7-L09 since last month. I bought it with a Sandisk Ultra 32gb micro sd class10. I've been using the phone without any problems. Didnt even tried to root it.
What i actually did was to set up the SD card as a the default memory location. I dont actually really know what this does apart from saving all media in the SD (mainly google play music, photos and videos i shoot with the camera, some big obb files, etc).
Last week i downloaded oficial Lollipop 5.1.1 release and did a manual update. All good, i kept on using it without any problems (aside from considerably lower battery life) for a couple of days.
Then i decided to gain root access. I followed this steps after googling for help.
I gained root access but after this, it keeps looping between "sd card safe to remove" and "preparing sd card" as long as my sd card is in its slot.
After that i:
Got SD card out, used a PC to backup contents (no damages), gave it a quick format in windows fat32, then format in android. PROBLEM WAS STILL THERE
Then i went back to the pc and gave the card a slow full fat32 format, then format again in andoird. PROBLEM STILL HERE
I also recently bought an action cam with the same SD model. Got that one out and placed it straight into the phone replacing the other. SAME TYPE of SD HERE, SAME MODEL. PROBLEM PERSISTS.
I think it might be related to flashing a recovery or something like that while i had my sd card as default memory location. I really dont know what to do to ger it read any of my SD cards again.
Shall i flash original kit kat firmware again? maybe 5.1.1 again and loose root access? I couldnt find any information regarding this issue rather than try another SD card which i already did (the problem surfaced after the process of gaining root access).
Any clues?
Thaks

I just started having this problem today. I have been on the official 5.1.1 since it launched and never came across any issue until this morning. I never ever rooted or flashed anything custom and the boot loader is still locked.
As of today I started having this issue, looping between "SD card safe to remove" and "Preparing SD card" however I am able to access the SD Card and intervals. The SD Card works perfectly fine on any other device.
One thing I changed recently (2 days ago) is the default memory location, I set it to SD Card, so I am going to revert that setting back to Internal Memory and see if it fixes the issue. Thanks for the tip
If anyone else has come across this issue and/or knows how to fix it please help
UPDATE: I tried reverting the default location setting back to "Internal storage" and found that the setting had already reverted back automatically, presumably because the SD Card is not always available So no luck with that. I am starting to suspect it's a hardware issue!
UPDATE 2: I left the SD Card in the device and connected it to the PC in order to take a backup using HiSuite. As soon as I plugged it in the error stopped cropping up. I finished the backup, unplugged the USB and so far the "SD card safe to remove" and "Preparing SD card" did not show up again. It's been over an hour now. Yesterday I plugged in the device to my PC in order to copy some pictures so something may have happened at that point I'm suspecting.

It's been over 12 hours now so I'm guessing all it needed was to connect it to the pc again [emoji2]

Now that you mention Hi Suite, i played arround a bit with it before the error appeared. im gonna give it a shot

I've done that the root and installed the recovery and microSD goes into loop does not know what to do help ..

Mine is still steady after a few days, hope you fix yours too [emoji6]

Solved. It must be some issue caused by HiSuite. I connected, made full backup, safely extracted SD from computer and problem seems to have ceased.
Thanks

I got this problem today after reflashing stock recovery.
It disappears after remove and reinsert sd card, but after a reboot problem was still there.
Now I solved checking debug usb setting, because after recovery flash it has been disabled itself.

I have this problem but with the USB storage device, I bought a new one which has two plugs, one is usb the other is micro, to transfer from laptop to phone without cables. It works on PC, it works on my husband's Huawei Mate 7, but just loops on mine. Other USB storage work fine on my phone with cable, but this new one just loops "preparing to connect" and " USB removed", even when trying to connect with cable.
All software is up to date, no modifications have been made.
Any simple ideas would be appreciated (I'm not into flashing/rooting etc!)

I need help my phone has gone to hell...

a couple days back I was copying all my songs from my phone's sd card to my pc. while copying something glitched out and my whole sd card and the folder i was copying to got corrupted so I had to say bye bye to all my data and start fresh (I tried using recuva, but the recovered files were still corrupted). I then was unable to do anything on my phone without it hanging for a few minutes so i decided to do a factory reset. now, my problem is that when I insert my sd card, and try to do something with my internal storage, it says internal memory not formatted, please try again, but when I remove my sd card, my internal memory works just fine. I have absolutely no Idea whats wrong. please help me fix this issue. also my phone was rooted before I did a factory reset.
