The sd-ext in CWM actually isn't what you're thinking it is. In CWM, SD-EXT is referring to one specific folder on the external SD card, not the whole card, and if that file isn't there, it throws up that error.
If you can see your external card by putting it in an adapter and hooking it up to your computer, I'd suggest moving everything off the card and onto your computer, formatting the card (FAT32, I believe), and then putting it back into your phone.
See if that helps.

Hey man.
It did not work!
The ext-sd didn't apears, even, at the configuration menu.
When i connect the celphone to the computers, appears only theo original sd.
I'tryed a friends sd, but it don't read to.
I thinking that is a hardware issue.
What could i do?

I'm not sure how drastic you want to get, but if it's not reading any external microSD cards, you could back up everything on your phone, then flash back to stock and do a master clear. That might set right whatever is messing up. If that doesn't fix it, you might have a hardware issue on your hands.

Thanks for the help!
I'll try this as soon as i can, and post the results in here!

I think I have the same issue. Sometimes it randomly pops up saying "blank SD card" or "damaged SD card" message. And I have to reboot to get the card to work again. And it may fail randomly later. :/

What size/class sd cards are you guys trying to use?

8 GB class 4 San disk

Kingston 16 gb class 4
My external_sd isn't working, neither randomly...

Do you have an adapter for the MicroSD that you could use to put it into your computer (outside of the phone) to test and make sure it's good?

I experienced the same erratic behavior with a new 16gig class 4 SanDisk. But, my 8gig class 4 SanDisk works perfectly. I'm running MIUI,btw. When I flash back to stock kf1, they both work perfectly.

32gb sd card

Hi guys im having an issue with a 32gb Kingston sd card, whats happening is that everytime i add files to my sd card from my computer it will show them to me that they are there. But once i put the sd card in my phone the new files i transfer wont appear :/. Ive formatted my sd card already like couple times and still does the same. Never did that to my 8gb card, and top of that when i transfer all my data from the 8gb to the 32 only half transferd and when back n fourth doing it folder per folder and just wouldnt show anything on the phone. Any suggestions, thank you

Going to take a guess and say you're on CM? If so I had problems with my 32GB too but on stock roms it works. I had to get a 16GB to use under CM. I'm not sure of the problem but there was my fix

Are you rebooting the phone after putting back the microsd? Sometimes that works.

As matter fact havent tried on Cm, im on MIUI right now. But im giving it one more try with the formatting see what happens if not will go to Eagle Blood see how that goes.

Yeah im since i noticed my sd card wouldnt show up unless would have to reboot. some files have been transfering but like awhile ago i d-loaded the files that needed for the game Modern combat 2 and after finished i rebooted or just quit playing and tried playing again and have to be redowloading the files over and over again since nothing stays on my sd card :/

That sucks, sounds like a bad sdcard. You still got the receipt?
I got my 32gb lexar class 10 with USB SD reader for just under 50 and its been issue free. Never liked Kingston products.

Tried formatting it using the phone itself? Miui is based off cm7 so that could be the issue as well.

Won't let me format it from phone since as soon as I put it in tells me "safely to remove card now" so kinda like automatically ejectects itself when I put it in. N got another problem :/ I bitlocked the sd card in my windows 7 laptop and as I was transferring files my wire was loose and we'll lost the connection and of course gave me files transfer error. But the problem now is that since I bitlocked the sd card won't let me get in it anymore, even though i put my password I put for the sd card. Just says something error with files and blah blah ;/. Can't even format or or anything anymore ;/

Found the solution for this problem with the bit locker > I mounted my sd card on my xp SP3 and formatted it and gave me the ize of 514mb i was like what. But i still did it and when i mounted it on my windows 7 i formatted again and this time showed me the 32gb size . So now its working properly.yeah buddy.

Moving from Weapon X to Miui rom my sdcard was detected fine but then after a couple of days of using Miui I wasn't able to open up sdcard when connected to my pc. It shown that usb is detected on my phone.
It only work when I restore back to WeaponX. I tried flashing different Miui roms, EagleBlood and PhoenixBlood. None detect my sdcard on pc except for WeaponX. I also tried to format my sdcard. Didn't work.
Anyone got any suggestion??

Try reinstalling ure usb drivers or not just restart the computer that would help with me. Or have you tried it with a card adapter?
Sent from my LG-P999 using xda premium

If you've tried it both with the USB cord and with an sd card reader, it might just be a bad sd card. This happened to me with a Samsung 16gb. I couldnt add or delete anything on it. Simply had to get a new sd card. Try out Lexar or PNY if you want a good one.

Question about Boot Manager

OK, so people talk about boot manager a lot, and something just came to mind... what would happen to the phone it you were booted into an SD card ROM, and the card was unmounted by accident? This could be a problem!
Sent from my Sensation using XDA

my guess is the phone will probably freeze or reboot, possible into recovery, if the sd was taken out. i dont think it would continue from the cache. if that happens you would need to go into recovery and apply the Rom Manager created update.zip found at /sdcard/BootManager/phoneRom once that finishes the phone will boot into the rom it has installed on the phone itself. i see using Rom Manager as a way to test potential roms anyway not to continue using from the card. especially if the card is class 4 or below. anyway, just dont remove the card and no worries

Thanks, that makes sense! But my issue is that infrequently, but it does happen, the memory card will RANDOMLY unmount... and then I have to remove it and plug it back in...

I also have issued with my new 32gb class 6, what I find is there will be corrupt file on SD card just few but make the phone always unmount. To solve the issues I have try format with various software and method. Even try using SDFormat tool but it will have same problem. After a lot of try I think I have a solution.
Format the microsd card on Storage Setting [ Settings > Storage > SD card > Unmount > Format ]. I also find the micro sd card can't be defrag or alter with computer.
I usually defrag with Defraggler, and it's always unmount. I think the phone can't really handle sdcard with class 6 and above because don't have issued with my other's class 4 card.
The Stock ROM I find always have issued than Custom ROM
Please backup or copy your file first to computer or other storage then copy back.
Just my 2 cent, do at your own risk.

I am running Stock TMOUS Stock Rom and like 2 days ago. My 16GB microSD Card randomly from working to "Blank SD Card' and when I try to format it on the phone, it says 'External Media in Unknown State' when I connect it to my card readers, and into the computer, it doesn't even find it inserted but the card readers work with other Micro SD cards. Can someone help me? Other microSD cards work in my phone, but not my usual 16GB one...help?

It looks like your sd card is corrupted. I would suggest using SD Formatter : it is a good tool for fixing corrupted sd cards and gives you lots of options.

It wont work on the sensation but it worked for me on an old phone about 5 years old minimum. Its worked for my friends as well..... otherwise if you couldn't do it this way or via computer then it wont be able to format, must be something else wrong with it, a good excuse to order a larger one as I see it

No, you can just use an old phone that can handle a microsd and it can do it for you. My friend did it through his five year old phone.

connect your phone to computer, Toggle USB mode in 4EXT Recovery, and your phone will act as a microSD card reader. You can do anything you want from there. =)

If the card cannot be mounted, both of these won't work.
Your best bet is to use a card reader & try different methods of connecting.
First put the SD Card in & then connect card reader, first connect card reader then put SD Card in, etc.
Usually, even a corrupted SD Card shows up on a PC.
If it does, use the format option. If "Windows was unable to format the drive", then go to Disk Management & format it from there.
If the PC is unable to detect it, then it's some kind of hardware fault & to the best of my knowledge, nothing will be able to fix that. All you can do is try wiping the contacts if they are dirty, but I doubt that would cause such a problem.

it will still work even if SD card cannot be mount.
Juopunutbear's S-OFF method sort of corrupted my SD card and i used Toggle USB mode method to format my SD card

A corrupted SD Card can still be mounted.
If the SD Card cannot be mounted in recovery, there is no question of trying to Toggle USB Storage or formatting it.
His case seems different.

wow i recover my files
hi guys, i had same problem, but then i set this sandisk ultra to my nokia xpress music and there was everything,,, my arc s cant open it anymore but nokia opens... try to reset your sd s to others phone...

I use 4EXT for my loader. If you have another loader you can try on that as well, boot into Recovery Mode and try to format the SD Card for there. 4EXT formatted my SD Card even though it couldn't mount it. Then it worked just fine.

Odd Issue With a Micro Sd

Hey guys this is my last place to turn before I just go buy a new one but I want to see if anyone at all can help me.
I have a Sandisk 32 GB Class 4 Micro Sd. I bought it off a guy on the xda marketplace and it was in the factory packaging and took me a half hour to get out so I doubt it was fake unless people forge the packaging.
Well the other day I went to copy a file onto the card by mounting it to the computer. It copied just fine but when I unmounted the card and went onto the phone the file was no where to be found. This was off to me so I mounted the card again and it opened fine but there was no file. I then copied it again and it said it worked like it normally does. i unmounted then mounted right away and guess what the file didn't exist.
This is where it gets interesting.
I then mount the card again and select everything and delete it all. It says it works fine. I then disconnect the card then mount it again and guess what all the files are back. Like nothing happened. I then proceed to format in windows by right clicking and hitting format. It didnt do anything. I then go into recovery on the phone and try and format it. Nothing happens. I then connect the card directly to the computer with a micro to sd card adapter that is made by sandisk. It mounts to the computer fine. I then go into Easeus Partition Manager and click format. It finishes and comes up with an error saying There are some error occurred while writing partition chains on disk.
If anyone has any idea please help.
UPDATE: I have contacted Sandisk and they are going to send me a brand new card.

Is the card detected by the mobile?
If yes, try to format it in the mobile itself with the format option.
Also check how much space it shows , before & after formatting.

Try low level format

Could be a duff card but sometimes I have had this if the card has not been fully un mounted try waiting a couple more minutes before removing the card to give the system time to fully un mount it
Or it will not be written to.
