Hi people!
I have seen many people have a problem with the above mentioned error in CWM. Although there are any threads on the topic, none of them are really clear (and often speculate) the method to fix it. And there is a lot of confusion regarding the "sdcard" in the i9003. This is my attempt to clarify and provide a reasonable fix (which worked for my Class 10, 16GB Micro SD (SDHC)).
It goes like this:
-> Boot into CWM recovery
-> Choose any options pertaining to the external sd card (such as backup, restore or install file from .zip)
-> The command returns with an error about how it can't mount "sdcard".
Now, there are a few thing that you have to be mindful of:
1) The "sdcard" mentioned in CWM for the i9003 is actually the external sd card.
- It is done this way so that everything works with the external sd and not with the internal 2GB sd that is present on our phone.
2) The internal sd is referred to as "sd-ext".
3) This pertains to the CWM of our phone. After booting into Android, it is back to "normal".
I tried to do a format in Windows 7's default formatting tool with FAT32, exFAT and NTFS (just eliminate the possibilities) with "default allocation size". It didn't work. Even choosing a larger allocation size did not work.
The Fix:
-> The optimal recommended filesystem for an android SD Card is FAT32.
-> Using the "SD Formatter" (version 3.1 as of this writing) from the SD Association ended up solving my problems.
-> The download link, for Windows (A MAC version is also available), from their site is here. You have to click "I Accept" and accept the terms of the EULA (but who really reads those things anyway ) ?
-> Use a card reader (using your phone is not recommended), make sure you have selected the right card and that you have backed-up all the data on your card (incase you didn't know - formatting erases all your data!).
-> I chose "Quick format" under options and made sure "Format Size Adjustment" was off (These are available under "options").
-> It's done in a few minutes, and it works GREAT! :-D
Cheers people! Hope this clears up some stuff!
This thread deserves to be made a sticky thread...
Moderators please make sure to consider this
Btw - nice job dude you explained it all very well!
Tapashocked via my gt-I9003 with a random keyboard of my choice !
Finally solution came..it works like a charm...thank you so much Bro..
I was bugged by the same problem a few moths ago....
I solved it by Going to Settings > SD card ad phone storage >SD CARD> Umount sd card > Format SD card....
@Lord: thanks mate!
@Symdroid: your welcome! Glad to have helped!
@Neojith: Yeah that usually works, but for some odd reason it didn't work for me last time.
Also, this works without fail even if your SD card is unrecognizable (or comes up as corrupt/damaged) in Android but is detected on the computer.

Man i dont hav any card reader....why cant i do this while it's inside the phone? :-(
Give it a shot... It may work (but be sure you're formatting the right card)!
I recommended a card reader as it is faster, and in most cases the card wasn't detectable by Android but was detectable using a card reader.

Got cranium ROM 3.1 and its not working on my phone. It shows the drive in the PC but i cannot access it. But the phone still reads whats on the SD card. It works well before with kPE...
kudos Erahgon, it worked!
FYI I didnt even use a card reader, used the phone itself (too lazy to search for a reader at home)
Srry guys, was outta town for a few days!
@vadexlux: Good to hear that it works from your phone as well!
@lbraddx : If it's not accessible even in Windows, your card is probably corrupted. Do a quick format in Windows, then use a data recovery software to recover your files. After that, format using the method in the first post, and remember to back-up your files.

cannot access from the phone. but when i flash with odin there is part saying 'error can't mount sdcard-skipped wipe data' but when i check the sd card from my pc its empty and i lost all my file in sd.
here another weird thing, you said the 'sdcard' in CWM is the external sd. I can't mount 'sdcard' but I can mount 'sd-ext'; when i took out my sdcard then I can't mount 'sd-ext'. so I think in my case 'sd-ext' is my sdcard. thanks for replying though. can you figure out my problem?

Flashing with ODIN? What were you flashing with ODIN? When you flash with ODIN it doesn't do anything to the external-sd card.
Have you done an internal-external sd swap? If so, and you want to flash a new firmware using ODIN, you must re-partition (i.e. Use the latona pit file) and then proceed with the flash. After the flash, you may once again swap the external and internal sd cards. I haven't tried this, so this is just my best guess. If this doesn't work, try using your old vold.fstab file (read this thread for more details).

still no luck
Fascinate owner here. Had the same issue with CWM red (3.x) and Green (4.x).
All I did was reformat the card in Android. You have to unmount it in Settings > SD Card. Then simply Format. All your data will be erased but CWM will be able to read your card again.
WOW... I have THAT trouble too (on a I9100!), read this (googled) post and think.. "hmmm.... all other works fine with the ext. SD-Card... that can't be the fix..."
BUT i test the fix and OMG!... Now all CWM troubles gone! PERFECT!
Thank you very very much! I love the XDA community! *smak* ;-)
Is there any way to do the same for the internal sdcard coz my external sdcard reads fine but internal phone memory as well as internal sdcard are corrupted!
WOW
hi dude..its works like..hapi man!!!Thanks alot!

I have been seaching for this problem, and I was lucky enough to come across your post. After formating my SD card within android, the problem is solved, and now I can backup to and restore from my external SD card. I am using Galaxy Tab 2.
Thank you!!
Was wondering if anyone had any ideas on what I can possibly do??
The card came as EXFAT, but most roms only support FAT32.
I formatted the card to FAT32 which was fine .. but after copying a few files the card now refuses to write or delete files. I can still open and view media that's on it but that's about it. I can't even re-format it, it will say the disk can not be formated or write error. The card isn't corrupt though, I copied around 30gbs of video on it when it was in EXFAT partition before. J
I'm using an SD adaptor into my card reader, but yes I have ensured the lock switch is off.
edit - oh also, when you place the card into the phone it'll say that the card is damaged/blank.
Any help would be appreciated
Cheers,

Make sure you format it in the phone
Every time I place the card in, it will say the card is damaged or blank
Then it tries to format it but then goes through the same loop of saying it's damaged/blank

i had experienced the same problem i tried my best using several fomat tools. think almost all the tools in the world....failed and bought a new one.....think its better go for new card
Did you try to format it on Linux? I've experienced some problems with SD cards formated on Windows (assuming that you run Windows )

pretty much - there's nothing you can do. I decided to email Sandisk and here's their response:
I understand that the error that appear after format is “write protected”. First we would like to apologize for the inconvenience.
I understand that you are getting write protection error while accessing the flash drive. The flash drive has detected a potential fault and become “write protected” to prevent data loss. There is no method to fix this. You will need to back-up your data and replace the flash drive.
So you have to RMA it. I'm abit confused because others on XDA have successfully covnerted their 64gb cards to FAT32 without any issues.
Could it be a faulty batch of sd cards?.
hi guy's!
i have a Galaxy Ace GT-S5730i
and i was having some problems with the internal storage
so i saw this thread by jocala
http://forum.xda-developers.com/showthread.php?t=1757767
that i can use the external sd card as an internal storage
any how .. it didn't work!
but what happened now is that my phone can't read the sd card at all
and saying things like "no such as directory" or something like that
and i can't download the swapsd.apk again cause it needs an sd card to be downloaded to first!
if only i can download the apk from any where directly to the internal phone storage
i can get the swap back to default again!
any help please?!
and yes i am a noob!
Take out the SD card and put it into an SD card reader and put that into your computer and use a free partition program to basically repartition the entire card or delete and format a new partition.
didn't work

hey, thanks for helping
but it didn't work
did what you asked me to do, but nothing really changed!
thanks again
any other ideas?
Strange, formatting the sd card usually fixes these kind of problems :/
Have you tried it a couple times? Formatting does fail on occasions. Also make sure you do a full format, not a quick one

well, the sd card is working probably on the pc with the card reader!
so i guess - just guessing - that the problem is in the device it self!
i formatted the phone it self but it didn't work, and i'm going to go with what you are saying
and i will do a full format
thanks a lot
didn't work, does the FAT,FAT32 and the rest of those stuff matter?!

when ever i open "My Files" it says "Your phone does not have SD card inserted" although it is!
take a cloth and clean your SD card area in your phone, also use that canned air stuff and do a quick spray.

So I understand you want you files and the card to work on the phone?
The phone supports FAT32 file system, if i'm not mistaken so you should format it to that.
Does a pc read the files on the card? Cause if so, then first copy them to you pc and after formatting back on the card.

Does the pc see the card and tell you it needs to be formatted or doesn't it even show on your pc?
If it doesn't even show up, you could be talking about a broken reader of your computer or a broken card.
If it shows up but you can''t acces, than it might be recoverable.

If your laptop's card reader is ok then check it form the device manager. Do you remember about setting any password to your MMC??
I've seen most of the PC doesn't show a password protected MMC.

Try testdisk (cgsecurity.org/wiki/TestDisk), maybe it can recover your partition table.
Good Luck!
Hello Guys,
After installing several of customized ROM's Ive noticed that I can not remove anything from my sd card. Mover, I cant even format it. I tried everything including to put a sd card into adapter and tried to format it under windows. Still, nothing heave helped.
I've used every toutorial from the web without success. Im asking you kindly for an advice.
Use a low level formatting tool.
The only card I -had- use that on to make it functional again failed. It never ran right; never lost data but the phone randomly couldn't detect it forcing me to reboot.
If it won't format on the phone the safest course of action is to deep six it and get a new card.
The risk of losing a data drive unexpectedly outweighs the cost of the card! Use only name brand cards purchased from trusted sources. Use V30 or higher rated cards. The Sandisk Extreme is a good V30 rated card. I have the .5 and a 1tb ones. Slam it in, format, good to go. Zero issues.
Once formatted on the device, leave it there. Don't swap it around unless you format it with the new device first otherwise corruption is possible. Do uploads/downloads through the device to the card. Always format the card on the device before use. If it has a dismount option always dismount the card before pulling it.

If you can't do a low level format the card is unrecoverable; trash. Sorry.
These cards can be damaged by ESD so keep the static down when handling them. If you can feel, hear or see static electricity there's more than enough to destroy the card. High G loading like a 3 foot drop onto concrete can cause internal damage as well.

Hi,
Heres the output:
If SD-card isn't write-protected
then you may dismount the drive ( from Settings->Storage ) and re-mount the SD-card what may fix the problem: Verify it by moving a file from internal storage to SD-card.
I can copy a file without any problem, but after restart, everything goes back to the beginning.
So if I copy file A, and delete file B (same folder - dload), after restarting the phone file B is back agaian in the folder, but there is no file A anymore in the folder. File A is gone.
