A week or so ago, I flashed this ROM onto my phone. ([ROM] (v1.2.6_r2) Nexus AOSP Gingerbread 2.3.4 - Faux123 [Jun-26-2011] - http://forum.xda-developers.com/showthread.php?t=1068367&page=189)
I had to end up switching back to stock ROM. Ever since the flash back to stock, my memory card has been "locked"
In the process of flashing my phone back to stock, my external Micro SD card became locked to "Read Only". I cannot format or erase any of the content that was stored on my card during the flashings. It literally seems to be "LOCKED" onto the card.
I've tried the windows format option in the Device Manager. I've also tried the Windows Command prompts. NOTHING has worked. Formatting the card in my phone does nothing. No data gets erased.
With the card in my phone, I can access all my files (movies, music, pics, etc). But I cannot modify, delete, or add any new content! (Example, I cannot select my External SD as a valid storage location for new pics in the camera.)
Does anyone have any ideas on how to reformat this card to get it working for me again. It is a 16gig card. I hate to throw it out.
Thanks.
I would recommend trying Panasonic's sdcard formatter. It seems to be pretty good at formatting sdcards that other programs have trouble with.

Another thing you could try, you can format your sdcard inside clockwork recovery mod. (Under the mounts and storage section if my memory serves)

Thank you for the suggestions
That did not work. I ran the SD formatter and the windows formatter and my content is STILL on the card.
CWM won't format the card either.
Any other ideas?
Did you try partitioning the card? Just one 16GiB FAT32 partition?

Joe -
That is officially over my head.
How would I go about doing that?
Can you get the card replaced under warranty?
Since you tried formatting the sd card, I am assuming you have backed up everything on it.
As easy way is in Clockwork recovery mod choose -> advanced; then choose -> partition;
when prompted for a partition size for the ext partition choose the smallest, also the smallest for swap (I think you can choose 0 for this one) continue to follow prompts and the card will be partitioned.
One more thing to try if that doesn't work:
http://gparted.sourceforge.net/livecd.php
Go to this site, download the cd or usb disk version and boot off it. Now, plug your card into your computer (NOT through the phone, use a usb reader. If you don't have one, you can probably pick up a cheap one for around 10 bucks.), you may need to rescan the disks after you plug the card in, to make sure gparted sees it. Now, delete the entire partition, so there is no partition at all on the card.
Boot back into windows, plug the card in, try to format it again. I've seen this happen when you have a damaged mbr on the sdcard. Also, when you format in windows, (if your system will allow it), id try to format it to a 64k cluster size instead of 32k. (on a 16gb card 32k is the default cluster size.) It'll speed it up a bit. (not really needed, but a nice boost.)
The last thing you can try, if all else fails, boot into clockwork recovery (assuming you have it installed) and format the sdcard through there.
If all that fails, I'd say you have a bad card. But try those steps first, hate to see you throw the card away if it's still good. )

Hi
Just wondered how i completely wipe all my data from this disk?
I can boot into clockworkmod restore factory defaults and clear cache. I just need to know how to wipe the SD card.
Trying to revert the phone to the beginning.

Settings/ sd card/ unmount sd/ format sd card!...
Sent from my HTC Vision
This worked to some degree.
Once I unmounted it and erased the SD card I couldn't mount or format the card again :/. Nothing I did worked.
I tried formatting my SD card when connecting the phone to my windows laptop but couldn't do it either.
I have clockworkmod installed on my phone and think I have found a solution.
Keep your phone connected to your laptop. If you reboot into recovery on your phone and go to "mounts and storage menu", then "mount USB storage". On your windows platform it should popup something like "need to format this drive before you can access it". so I formatted the drive, fat32, allocated unit size 32kb, check "quick format". Start.
once it's done in windows, select in clockworkmod "format /sdcard" and then "mount /sdcard" and reboot.
It should work.
In case this helps you along the way - this program seems to come recommended for formatting SD cards.

I tried that a couple of days ago. Formatted my new 32GB microsdhc card fine. But XP Pro (with SP3) couldn't see it on my desktop so couldn't drop all my data onto it. In the end I formatted the card with my Nokia E71, mounted it as a 'disk' on the PC and all was fine.
(Didn't do it on the DHD 'cos I didn't want to tie it up for 7 hours copying all my music across)!

If your PC environment is Windows based, you may want to think about using SyncBack Freeware. It will ensure that every file has been moved. I've been using this to move large folders/directories for many years.
to lee droid hello.
i am a "silent admirer". i have a rooted desire and i use only leedroid roms for more then a year. as always i never had any problems with any of the roms and install them all without wipe at all.
about a month ago i installes v. 2.3.
today i saw the thread about the new version 3.0 gb and downloaded the following files: 1. 3.0 gb leedroid rom.
2. the new radio ...56....
3. the ext3 file.
after downloading i checked the md5 of the first two files and found it OK.
i backed up my 16 gb sd and tried to install the 3.0 tom via rom manager.
the thing is that i believe that the rom was install OK but the rom did not go up and my desire got stuck with the dumb green "htc".
thereafter i restored the system which went well and tried again - this time with file and cach wipe.
again - all seems to go well but did not load.
tried to install the ext3 file - went ok but did not load.
from that moment i got really worried but nothing i tried (deleating the sd card and copying from backup) or thought i know didnt work and now i am the proud owner of stupid green "htc" screen.
please help
erezinna
p.s. i couldt read all the 53 pages of your thread so if anybody already got an answer - please send me there.
I had this same issue.
It seems that although I originally partitioned my SD card as ext3 at some point without me knowing the partition got changed to ext4 I really can't explain how as I never messed with partitions after I initially set them up.
if the EXT3 fix is not working for you try booting into gparted and checking the partition there. as soon as I did that and realized it had been changed to ext4 I deleted the partition and made a new ext3 patition and it worked flawlessly after that.
"try booting into gparted and checking the partition there"
where? when? who?
can you you be more gentle? i booted milion times and never heard of "gpart" (it is a secret socaity)?
it's a live cd that you boot into on your PC to partition the SD card with a ext3 partition.
just google gparted live cd
You need to verify that the second partition on your sd card is in fact ext3 or leedriod will not load
i have to burn it or ghost-burn it or just download it and transfer to my desire?
like i said in my previous post you need to boot into on your PC.
I have to ask how did you originaly partition your SD card?
dear larkspeed:
i did all you have suggested but the gparted (or the regular win 7) was unable to recognize the sd card at all.
i did recognize all the other harddisks on my computer. it is probably because of the ext4 and now i cannot delete it. (also i hardly can operate the phone - only basic functions).
what sould i do now?
Windows will not see ext4 at all but it will see the partition itself so you can delete and remake it.
Gparted should have seen it just fine and let you reformat it to ext3
However if neither windows or gparted can see the partitions on the card then it's very possible the card itself has a fault.
Stupid question but when you loaded gparted you did use the drop down in the upper right corner of the window to actually select your sd card right?
if not then you were looking at primary hard drive only
yes i did several times. you have to move with "tab" and keboard because the mouse does not work there.
if the sd card have a fault, should i format it or erase it totally or something?
if you are totaly sure you have a ext partition on that card you will need to delete that partition either with windows **** manager or gparted
if you just format the card it will only format the partition it can see which will be the fat32 partition.
Now I assume you are putting the micro sd into some kind of adapter to plug it into the PC.
Now I have 2 options for this a USB stick that the micro sd plugs into or a micro sd to sd adapter plugged into an internal card reader which plugs into a USB header on my motherboard.
both of these systems work fine for me.
if gparted is not seeing the card at all then I would think whatever system you are using to plug the card into your PC is not supported.
I have to ask when you plug the card in when in windows what size does it say the "removable drive" is?
1. i gparted the sd card into main fat 32 partition about 12 gb and 1.6 gb ext3 partition
2. i cloesd the program after compleating that and the device informed me that the sd card is damaged and needs formating
3. i formated it and moved the leedroid 3.0.
4. it refused to go into recovery because lacking .update.zip file so i copied that too.
5. i installed the 3.0 but i won't go.
6. what to do? give it up?
all I can suggest is to try a different SD card and see if it works then.
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...

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).

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!

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!!
My SD was acting a fool (after deleting many ROMs, it still said I had 73MB free). Nothing I did would change it so I decided to format the card. I used Disk Utility (on Mac) and formatted for FAT32. After I did that, my phone said it was in a format it couldn't recognize, so I formatted it from the phone itself. Now, when I enter recovery and attempt to install zip from sdcard, then choose zip from sdcard, it says "E:Can't mount /sdcard". I don't really know what to do, as I formatted it from my phone. I figured that was sure fire but I guess not so much. I tried to find what format I need the SD card in to work properly but I couldn't find anything.
Can someone help me out?
Fat32 is correct for the phone. Do you have a usb reader for the sdhc microsdcard or one of those sdcards that let the microsd card fit in to read it from the pc?

Reboot in recovery, if it says it can't mount it... pop out the sd from your phone and pop it right back in and see if it works. No need to mess with mount points for it either.
Also, did you check if your lost.dir folder is taking up space? Sometimes that thing can get big.
Could have been a bad flash, try to flash it again. I know I had a problem when I bought a new sd card. You can also try to flash it from a different phone. Otherwise, if you have access to a pc, I can tell you how to format it from the command line, which is, in my opinion, better to do if you're having a problem with the quick format that the phone does.

Sounds like what i did one day when i wanted to wipe everything so i did including formatting my SD card through recovery. so it left me with nothing on my phone including a bootable rom! lol. if this is the case with you. Here is what i had to do. Download a new rom to my PC then plug my phone into my PC via USB/ Boot into recovery/ Mount storage/ Mount SD card/ Copy the Rom to SD card then Flash the Rom. Not too sure if this helps, I hope it does, again it sounds like the same problem i had.
Sometimes SD cards break...for some reason they will just stop working, probably due to manufacturing techniques. My old 256mb card went bad, I just tossed it yesterday as a matter of fact. it had no name brand. I still have a 4gb pny that works perfectly and a SanDisk 32gb which also works great. If you do have to get a new SD card, I would recommend getting the highest class you can afford highest out the right now I believe is C10. That will increase your transfer speeds....both of my current cards are class4 and it can take a little bit of time to transfer gigs of data between the phone and computer. If you have any other device that can accept the "card" put it in there and check if it can send and receive data/ format to proper disk size, if not then your card is broken.
Once you go class 10 you don't look back lol

So I had this 8gb micro Sdcard that came with my phone and for Christmas I got a 16gb one. I had a lot of precious stuff on the older 8gb, so I put it into an adapter and connected it to my PC, planning to backup the contents and then put it on the 16gb. But when i connected it in, it said "This card needs to be formated before using". I first i thought the adapter was broken, so I put the micro sdcard back into my android phone so I could connect my phone to the computer and do it that way but when it turned on it said "Sdcard ready to remove". The phone wouldn't recognise it either!
I have already put other micro sdcards in the adapter and they work perfectly.
I have a lot of precious stuff on the micro sdcard so if there is a way to fix it without wiping everything, I'd be really happy to hear it.

Maybe try disk manager on your PC and see what format is says the card is..
otherwise try the phone again and again hopefully it will work. Ive had that before and a combination of playing with disk manager and the phone I managed to get the stuff off my card

i would try inserting it into your phone several times to try to get it to catch..also reboot phone while card is inserted..if you have to format the card you can still get everything off of it by using a program like "recuva" .. ive used it many times and it works like a charm..nothing is ever erased on a sd card..its only overwritten..so as long as you havent overwritten anything on the card you can easily get it back..formatting will not overwrite anything
Connect your card to pc, open mini partition tool wizard. Click on your memory in program and next open.
I tried putting the sdcard back into my phone several times and always didn't work . I went onto diskmanager and see screenshot below for info (it's g/ drive). I then tried formatting with various settings and always got a failure see second screenshot.

Hey. Thanks for the reply, I installed that program but it confuses me. How do i access my sdcard with it?
My sdcard is not partitioned or used for swap or anything.
Oh and I've tried formatting with exfat, fat, fat32 and NFTS and always fails
Do you see your sd card in this program? If yes try wipe volume
I checked your screens and your card is RAW- file system is broken or is unknown to the windows , try this:
1
close ALL your programs, insert your sd card to your computer and ONLY WAIT,(15 min.) do nothing, dont touch mouse (weird? yes but your computer will try to repair file system, fot 2gb is less 5-10 minutes, but your is 8 gb class???, that wait more)
2 (optional, but you should try 3 point)
Format your sd with windows installerr (format it during window installation using windows setup disc) you can cancell instalation after format without probles
3
If still nothing (after 25 minutes) try this program http://panasonic.jp/support/global/cs/sd/download/index.html - IT IS LAST OPTION WITHOUT SPEND MONEY
