SD card not Mounting Cyanogenmod

Ever since flashing cyanogenmod 6 I have been having several probelms
1. My SD card is not mounted and not recognized by anything. This is stopping me from accessing rom manager or making any changes.
I have tried several things including reformating my sd card and removing files just in case it was to full. I have not been able to figure out how to partition it to part fat32, part ext yet. I am running out of ideas and getting very frustrated with my phone. I have three sd cards to work with and none of them are recognized.
2. This would not be a problem if I could just go to stock. Unfortunately I can not get my pc to get me into recovery so I can preforma NAND backup or flash a different rom that is closer to stock. I think this may have something to do with my sd card not being recognized. I have also tried the workaround involving no pc but still am getting nothing,
3. I am also having issues with usb connectivity.
I think if i can either get my sd card mounted or my phone to enter recovery mode so I can flash another rom, add the google add on, or do a NANdroid backup it would take care of my problems. If any one has a great idea as to how to get my sd card to be recognized I feel that would solve most of my problems.
Thanks Brad

Hey I have the same problem!
Could you solved this sd card issue?
Thanks

[Q] CyanogenMod 7 is ruining my SD cards

Now I'm not moaning about CyanogenMod here, I'm just trying to understand how I can fix the issue.
Basically, I had CyanogenMod 7 RC2 on my Desire Z. That was it.
Eventually I saw through ROM Manager that the full release of 7 was out so I downloaded, took a backup, wiped everything and did a fresh install of the new ROM.
It installed fine, but none of my apps that needed root access were getting it.
So I booted into recovery, restored my backup, root was back.
I then installed 7.0 over my RC2. That worked fine, but again root was gone.
At this point, my phone started damaging SD cards.
It suddenly started saying that my 8GB card that came with the phone was damaged. I tried to fix it on the phone, but it just said 'Checking card' and then giving up.
Putting it in an old MP3 player, it is not detected at all.
Putting it in a card reader, the card is unreadable and when I try to format it Windows says the card is 'read only' (this is not due to the reader).
I put a functional 2gb card I had lying around into my Desire Z and it broke it in the exact same way.
My question to you guys is - what could be causing this and how do I fix it because I have a 16gb card coming and I'm obviously cautious of putting it in the phone.
Also, how would I go about flashing the new Cyanogenmod 7.02 ROM if my phone keeps breaking SD cards I put into it?

This error can be because when ever you install a CyanogenMod ROM over another, It leaves files your new ROM think is useful such as data that the new ROM doesn't support. It is damaging your SD Card because it keeps attempting to fix the error but is making it worst by trying to remove system files. Your best bet is to try another ROM and see if it does the same thing and report it to CyanogenMod Developer Team if it only does this to CyanogenMod ROMs otherwise it would be just a virus on your SD Card feeding off of personal data. If it is only CyanogenMod ROMs, we will adress this issue ASAP. Hope I helped

Thank you VS4, you are indeed helpful
I've since heard some people have managed to fix their SD cards by formatting them in ClockworkMod but I can't even mount it first in order to do this! Is my card truly dead?
Also, do you think the reason that CM7.0 had no root (even when it was a clean install) was due to me not 'fixing permissions'?
Thanks

Just a note to say that I've managed to fix it!
Despite being unable to 'mount sdcard' in clockworkmod, I found I was able to activate USB Storage and through this I was able to format the card (Windows 7 was previously saying that the same card was 'read only' in a multitude of card readers).
I hope this helps any poor chap with the same problem.

I had this exact same problem, munched 2 of my 8GB cards, and had a 16 on the way. I somehow fixed it before the 16 came and I've never had the issue since, glad to see an explanation of it.

Thanks, nofixio!
I had the same problem on my Samsung Fascinate with CM7. It ate my 16GB SD card to the point where the phone wouldn't recognize it, CWM wouldn't mount it, and it wouldn't show up on my computer in multiple SD readers.
I wasn't quite clear what you were suggesting when you said you were able to "activate USB Storage." I thought maybe you meant within CWM. That didn't work for me, but I was able to boot the phone up with the problem SD card in it and turn on USB storage as normal. Suddenly my computer could not only see the SD card, it could see all the files that were on it before it died! I backed everything up, formatted the card in Windows, and everything's good now. Thanks for the tip!

I'm not sure why you would ask this in such an old thread but... Try just plugging it in to your computer maybe? What ROM are you on?

im running cm7 ... it wont read from computer. i tried several micro sd card readers. it just tells me it cant format. its just like what was mentioned before.

Weird, I've never had any problems with Cyanogen 7 roms. I've flashed one over another and had no issues at all, Mayb because I use SuperWipe before hand? Or maybe its a certain sd card issue???

Running Desire Z and Andromadus Beta 11 I had similar problem after I had applied remote wipe from Exchange (wanted to see if it works). Remote wipe worked: it destroyed contents of SD card and erased phone back to factory settings. After wipe mounting SD card failed and Andromadus seemed to be unable to format the card.
Solution: Booted phone to Clockwork recovery and applied advanced -> Partition SD Card.
Posted this on this thread since it came first when searching solution.

Go into Recovery (Clockwork), go to mounts and storage, then scroll down and it should say mount USB storage.

[Q] SD Card not being read, can't go into clockwork

Hi all,
So I woke up this morning with my phone displaying a notification that my sd card is blank. I've had data2ext installed for about a month now on every other cm7 nightly, the latest being #108. I tried to mount the sd card, only to see the same notification. I've tried rebooting, battery pull, booting without the sd card then inserting it and nothing has changed. I went as far as trying to install the htc 2.2 update... and it failed since I'm not on an htc rom. The weird thing is my "about phone" section still shows 244 mb available of 418 mb total, although this might just be the ram/rom, not data partition... So what can I do? I also tried rebooting into recovery through cm7's power off menu AND rom manager, only to be shown a phone with a red QUESTION mark instead of the triangle and exclamation point. When I tried formatting my sd card, i get a pop-up notice saying "SD card is currently being checked". Help me, xda community. You're my only hope.

I tend to be the guy who asks the more obvious or I guess overlooked stuff... So I will!
Now to me(and I'm no expert here...) but it doesn't sound like a problem with the SD card(or maybe it is!). Have you tried a different SD card? Or using the SD card in a different device?

I didn't have a micro sd card adapter or any other micro sd to try at the time I wrote the OP so I didn't include that in there. I have an adapter now and the computer recognizes a drive there but it only shows the swap volume, I believe (it says I need to format the card, and when I try to it only shows it as being 30.6mb). When I try to format I get a "Windows was unable to complete the format" notification. So yeah, that's where I'm at.

try paragon partition manager, it usually gets the job done for me.

I'm trying to use partition manager, but I still only see 30 mb on the sd card. I'm not exactly sure how to just clear the whole thing of the ext partition and swap volume, though.

can your partition manager delete the swap partition?

Have you tried gparted? that's the only way I could really customize my sd card with the different kinds of partitions.

Partition manager hung while trying to delete the partition.
Gparted failed, I don't remember the exact message on that one.
I tried a different microsd card and it was recognized by the phone, so something weird must've happened to my original one. I guess a year's worth of use is all I can ask for with tech nowadays. Thanks for the help, guys.

Did you use gparted from a live cd, or on a computer actually running linux? I have had gparted live cd's fail me, and then turned right around and had success with gparted installed to ubuntu running on a win xp machine through wubi. Might be worth a shot for you, just make sure to unmount the card in gparted, and to actually make the changes before exiting, as that's an easy mistake to make

I used both, now. I had run redo backup software with gparted off my usb drive and then I installed xubuntu to dual boot my machine, and both only recognize 30 mb of the sd card's 8 gb, so it's only the swap space that was formatted for my data2ext. Thanks guys.

SD card not recognized by ROMs?

Strange problem with this desire, I can access the SD card from recovery with stuff like USB-MS and flashing from SD but with stock it says the SD card isn't recognized (the options in Settings are all grayed out). With a rom that has Apps2SD like InsertCoin where some of the main apps are installed to the card it just leaves me with a blank screen on boot with the background/top bar still there.
Pretty strange desire really, when I first looked at it the problem I mentioned above was happening (it was originally on InsertCoin, worked for around 4 months before this started) so I reflashed it to stock and then had it returned to me with the owner saying that their SD was broken.
If anyone knows how to fix this it would be much appreciated as I'm as stuck as a brick wall right now :/

Explain your problem in no more than 2 sentences that actually make sense and I may be able to help you out.
Add on information such as
ROM you are/were using
Can you boot
Does PC recognise phone
Hboot (S-ON/ S-OFF)

Have you tried with another SD ? Maybe it is the SD thats broken ?

Sorry, let me dumb it down a bit:
In Amon Ra recovery it sees the SD card fine and lets me use it over USB fine too but when I boot up into a ROM it doesn't seem to find it.
Using InsertCoin/stock ROM and neither recognize it, it boots up fine and the PC can see the phone too, but since it can't mount the SD card I can't use disk drive mode :/ It's using S-OFF hboot too.

The SD is fine, it works in recovery and in my own desire but I've tried another SD card to be sure and still nothing

hmm ok try to reformat the SD card using recovery and tell me if it works

I've had/got a similar problem. I believe it's a problem with the contacts between the sd card and the 'holder' for the sd card.
Try removing the back of your phone, removing the sd card, pushing down on the metal 'holder', replacing the sd card, and rebooting.
This works for me for anything between 1 minute and a couple of days before the problem starts again.
I have no idea why the card is still accessible in recovery. If the above had no effect then please ignore!
The only solution, and it's really not useful, is to remove the sd card. I've returned my phone for repair and nothing got replaced (my guess is because the sd card is still accessible on recovery)
EDIT: No longer convinced it's the contacts as whenever my phone 'freezes' if I reboot into recovery the sd card is always accessible.
Now think it's to do with the file system/structure on the sd card becoming corrupt.
If I format the sd card as one single fat32 and keep ALL apps on the phone then I have no problems.

[Q] SD card unexpectedly removed / Damaged SD card

Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.

Maybe its a bug in the rom?

Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?
Sent from my One V using xda app-developers app

OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!

Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?

Just enter recovery and use adb sideload to flash a ROM.

But I need an SD card in order to use ADB sideload!
It fails every time because
Code:
E:Unable to mount /sdcard
Is there ANY way to do this without an SD card?

OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\

Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.

Have you tried formatting the SD card with your computer?

Yes, tried formatting SD Card using computer. Works fine when connected using adapter. Not detected when phone is connected to computer.
