My solution for the case of "SD Card blank or has unsupported filesystem"

Hi guys. I got a problem with my SD card after I recorded a video on my Nexus One (rom from Paul for very first Froyo over my rooted Nexus). I tried to to mount the SD card to my computer, but after clicking on the mounting button, the card appeared to have something wrong and displayed the warning message "SD Card blank or has unsupported filesystem". I could not access to the data on the card. I cared about my data so I tried to get the card out and used a card reader to read the content of the card from my Windows machine, but it seemed that Windows could not recognized the card. I thought the card was spoiled. I tried to save the card anyhow by trying to format it since I had the backup data on my computer already. Because I could not see the card on my Windows, I could not format it. I tried to format it on my N1, but after clicking on the format button, nothing happened. It seemed that my SD card was really spoiled.
But actually, I found a way that could help to save the SD card for my case. My solution is to try to partition the SD card using the ultility from my Recover section (I am using RA for nexus 1.7.0). The card after partitioning seems to work ok again. So I think the problem for my case is that the recording application already overwrote some data to the partition table on the card and that made my card inaccessible. Partioning the card again will help in this case but about the existing data on the card, I am not quite sure if it is still there. For my case, it's all gone.
Just a little experience to share ...

Hope this solution helps! Am doing the recovery thing now...

You can try to partition your card on an Android phone with RA 1.7.0 (or newer) installed. You can have a look at following page which is about RA for nexus v1.9.0 alpha:

whoa whoa if you have a galaxy s, do NOT flash the one he linked to. that is for the nexus one only. if you need to partition in windows, try plugging in the card to a reader and opening disk management (type "disk management" w/o quotes after pressing the windows key)
right click the card and hit format

Check your data before formatting it may not be corrupt
I had the same problem, rather than format the card straight away, I mounted it in ra recovery so that it was accessible over usb, then copied off all my data before formatting the card.

[Q] SD Card Help!

Hey guys. I'm currently running this ROM, I've been using it for a few days and have had no problems but today, when I turned the phone off and turned it back on, it took ages to turn back on. Then when it did it all looked them same but was kept freezing etc., then up in the notification bar it said "SD Card Removed Unexpectedly" then my phone went crazy with FC's.
So I took out the battery and restarted the phone. Then, it would turn on and go to the lock screen but then it would reboot and be at a continuius* boot loop of the HTC 'Quietly Brilliant' screen.
So then I took out the battery again, this time I took out the SD card too and booted up and my phone was normal again. Obviously with no phone storage though as there was SD card in. Then after I just skipped the setup I put my SD card back in to my phone and went to the music player and all my saved songs on my SD card played. But no internal storage (I have the SD card partitioned with a 1GB Ext3 partition). Then with the SD card in knowing it still works I rebooted again, only to come back to the HTC screen again.
So basically, how can I fix this?
If I'm going to need to format my SD card is there a way I can backup what's in the Ext3 partition?
Thanks,
L.

Bump. Need to be able to use my phone properly again urgently. Thanks.

It sounds like something is really funky (faulty hardware?) with either your SD card or your phone. You could try reformatting it with that Panasonic tool...
You can backup your SD-EXT partition with CWM/CWR. You can boot CWM from MAGLDR without flashing anything. Just put zImage and initrd.gz from the CWM download on the root of your SD card and boot "AD SD" from MAGLDR.

Thanks for the reply. It's not the phone as I have a 2GB SD card in it right now but that's not big enough.
Yeah I have a problem with CWM, when I click AD SD it says some Kernel error thing.
Is there any other way to find the files in my Ext partition using my computer?

Unfortunately not that I am aware of. Where are the CWM files located on your SD card? Are they on the root or in a subfolder? Did you modify the path MAGLDR looks for the "AD SD" path? Are you using the latest CWM release?

Yep they're on the root of it. I think it's 1.12 I have ATM. How do I modify the path? :S

Nevermind. I tried re-installing and it worked on my 2GB SD. But the thing is, the files I want are on my 16GB that won't read lol. I'll try flash it on that now.

Tried to flash my 16GB. Says SD Kernel Open Failed in red letters? Works with my other SD card though? :S
Now I just tried with my 2GB and it's saying the same thing again.

Cyanogen NAND on HD2 SD card trouble.

Hi, I recently flashed my 1st ROM, an Android rom to my HD2. I followed a guide in a recent edition of Micro Mart magazine. Everything went great & the rom is up & running, the only problem i'm having is with the SD card. I just get a notification saying 'SD card damaged'.
I've looked around on the forums & i've read numerous threads on SD card problems but I don't know which is relevant to my problem. The SD card works fine in other devices, just not on the Android rom. Im using the Cyanogen 'gpc_hd2_gingerbread_v1.7' NAND rom. Do i have to create an ext3 partition to get my SD card recognised?
Sorry for another SD card thread but this is my 1st time flash & Android rom so I really dont know about these ext partitions and how they are supposed to work!
Thanks for any advice in advance,
Tom

You might want to reformat your SD card. Get your SD card out and format it to fat32(important) using a card reader. Also make sure to backup your SD.
Try that.

Sorry I forgot to mention I tried it from a fresh format in windows, although I've read about the Panasonic formater so I could give that a go when I get home.

Yes you might want to reformat your SD card I suggest you use this software to format it. Also make sure you do a full wipe and format it using Fat 32.
One more thing is have you checked to see if your Android is mounting your SD card? When you boot your HD2 up and you see the Android lock screen appesr do you see it say preparing your SD card at the top of the screen?

Yes I remember seeing it saying preparing but then it just switches to the damaged notification. If I then select that, it brings up a box saying it may need to be formatted but selecting that doesn't seem to do anything, the damaged notification just stays there.

I've got it working. I followed the guide in this thread & it worked 1st time. Just follow it carefully and slowly

[Q] Can't format my sd card!

So about a week ago I downloaded new version of icecream tosti's ICS rom (v0.6) and booted into CWM to mount my sd card and move the zip file over. I noticed that it was taking longer time to move the file than it usually does but I let the process finish. I unmounted the card and went to install the zip from sd card but couldn't find it. I tried to move the file again and again but couldn't get it to copy the file onto the sd card. I tried moving files from the sd card onto the computer but that was not possible either. It wouldn't show me errors and complete the moving process but it actually didn't move anything. I thought there was something wrong with the sd card so I tried formatting it... no success!
I have used easues partition manager, mini tool partition manager, hp sd card utility, panasoic sd card formatter, tried formatting it through windows native options, used disk management, even tried formatting it through CWM but i kept on getting the same error, can't format. I was placing the micro sd card in a usb card reader and sd card reader in order to format it through computer. I have also tried using different computers but that didn't solve the issue. The problem is that every time I try to install a rom it reverts back to an older revision of the rom with old settings that I set before. It seems to me some how the sd card is locked in a previous state and it is write protected and won't let me format it.
Does anyone have any ideas on how I can solve my problem or does this mean the sd card is gone and I have to buy a new one?

I have exactly the same problem after using NexusHD2-ICS-4.0.3-CM9 V1.3. It seems this sd card was frozen, nothing on it can be changed. If I copy a file to it on computer, it shows copy successful, but that file cannot be read, and if refresh it shows nothing have changed in the SD card.
Anyone have any idea about this?
I have three broken micro sd cards now, two from WP7 and this one from ICS.

I waited a couple of weeks for someone to answer on this forum and tried all methods possible to format the sd card or revive it somehow but no luck so just recently purchased a new sandisk class 4 sd card hopefully this one doesn't go bad either. I just wish I knew why it was happening so I don't repeat the process again and end up damaging the card.

Have you tried to format with MAGLDR and after it on windows 7 pc ?

I did that, also followed this post:
http://forum.xda-developers.com/showthread.php?t=1283232
Contents on this sd card just refuse to change.

is there a solution to this coz im having the same problem and cant find a way to fix this

you can do it by this software's :
HDD Low Level Format Tool
MiniTool Partition Wizard
EASEUS Partition Master
Partition Wizard Home Edition
.
.
.
.
but i dont know how create swap and ext4 partitions on sd .

This happen because you formatted the card on the phone. I never recommend to format on the phone the cards but on PC. Try the application I posted on computer with FAT32 in 32768 unit size.

Can't Mount SD Card in CWM 5.x!

So i went to flash a ROM and now it says while flashing that the flash was aborted because the system can't mount the SD card. I'm using the newest CWM and have flashed stuff before. Not sure what to do, it wont let me make backups, restore, or flash anything.
I find it kinda strange, because once I reboot my tablet, everything's working fine, but it's not letting me install a custom rom
And yes, I have...
1. Unlocked by booloader.
2. Rooted my phone along with installing superuser.
3. Installed CWM recovery through fastboot (or whatever it's called, lol)
Has anyone gone through the same thing?

Bump....
Cm on guys I really need to get this rolling ...

What class SD Card are you using? I have issues with CWM on this Tablet reading anything above a class 6. I have a Class 10 SD Card that I have to swap Out and put in a different slower class card to flash roms and what not so I personally have had to deal with this because of the speed. Anyway hope that helps you out.

I'll try another sd card and see if it work out. Thanks for the advice!!

Bump. Using a different SD card didn't work, unfortunately

Back up all ur SD card files to PC
In CWM, you will find a Advance/ partition Sd card
Use this and make a 128 mb one, Reboot to CWM and CWM will recognize your card.

thank you very much....really helpful

Please help me i have a similar problem. I tried to partition it and it worked but it wouldnt recognize my sd card. Idk what happened maybe i formatted by mistake and now i dont have a system (or atleast it wouldnt boot up) and i have a cwm that doesnt mount recovery so i cant flash.
please someone help me! i need my phone

FIXED!
Nevermind. I did it wrong. U were supposed to partition sd card make it 128-128 and then while still in advanced setting restart launcher. Then you have to go to mount the card manually through mounts and storage.
if you just shut down the device it wouldnt work.
thank you for helping me fix this demonntl
