Problem with Micro sd card

I have AT&T Tilt with Sakajati's HyperDragon IV Windows Mobile 6.1 OS ROM, I also have this 8 GB micro SD card, which has around 3.5 GB of data, but for some reason I am not able to write on it any more. When ever I tried to format it I get this message which says " The card is write protected" I don't remember putting any password or anything. I can read data from that card on any computer or phone, but can write anymore data on the card. I can't delete anything from the card either.
Can someone suggest what could be wrong with the card and how can I unlock it?

I have tried low level format also, the format completes without any error, but when see in file explorer all the files are still there. If I try to format from SD formatter, I get error "The memory card is write protected", windows format doesn't give any error, just runs and in the end says "Windows can't comeplte the format". Card is working file and have no problem in reading the data it has, just can't write new one ot delete old one.
This is very weird problem... any help/comment is good.

Not sure if this will help....
I've had very similar issues over time...
Because of high TomTom & Music Use.
Both are loaded and work off my SD Card (6 GB worth)
What I finally found that worked for me, was to get a 2nd card and backing up my SD card to my Desktop PC, so later I could transfer to the 2nd SD Card when needed.
Then I do a Complete Format [Full FAT32 Format] of the old SD Card, via the Mini SD adapter on my Desktop PC.
I found that formating within the phone doesn't always work...
If this is not the case I can think of 2 other reasons for potential problems..
~Some ROM's require the removal of SIM & SD Cards when installing?
~If you were using an adapter formating the SD Card and it was not set to write mode?
Best of Luck!

JAC,
Thanks for your reply, but I have already tried FAT32 formatting using micro sd card, but as I said before, but it errored out.I even tried low level format, but didn't work. There is no locking swithc or anythign in micro SD card, not sure how the data can be locked. If it was ecrypted I was not able to read data on other devices. So what happened? Any help!!!

Like everything else, sometimes things just wear out, break or are just low quality to begin with. If you can read it on other devices, then transfer it and get a new card.

There is also a trick used by nefarious suppliers that takes a 4GB (or any size chip) and format it in a way that it appears as a larger chip. Then when you go to write to it the whole thing goes crazy.
This is why I recommend using reputable resellers and buying good quality Name Brand Chips, Like Sandisk or Kingston.

[Q] SOLVED: Connecting with USB shows only internal memorycard...

HI!
I have this problem that when I turn on the file sharing, the computer shows only internal memory card and not the external. Because the phone itself recognizes the external card I have tried to unmount and mount several times without any improvement. I am currently using the latest CM7 nightly, but the problem seemes to have started after I changed the card from 4gb to 16 gb. Any ideas?
EDIT: Erasing sd card from the phones menu helped to solve the problem.

Go Setting>Storage and remount your sd card and try???

I've done that several times....no help... android system accesses the card without problems...music, pics etc.

Did you physically remove your card and reinsert it, or just software remount?
Have you tried the card directly in your computer?
Have a look in windows device manager and see if it reports any problems. (right
click my computer and select manage)

I have tried it all and everything is ok with the sd card itself (I copied recent nightly from the computer on the sd card) also recovery recognizes is... there are also no problems in device manager...

Try to put on debugging mode. And try it with debugging mode on.
If the debugging mode is on try to take it off.

I tried that also and nothing changed.... I have a feeling that it is somehow attached to me using mybackup pro... I restored application apk and data from another phone to this one and It seems that usually the application data should go to internal memory card. In this case it is on external card... so i believe that somehow the programs are still using the card when connected and do not allow phone to share it out... It's just a guess though...
EDIT: so I think the solution is to wipe everything and start all over again

So I fresh installed Rom and wiped everything and the problem still exist... still can see files with file managers in phone and when connected to computer, autorun shows only internal card...
Edit: I tried now 2gb sized sdcard and it works perfectly... the problem is with 16gb card.

Weird. Did you try another USB-port?

I tried different USB-s now and still same I found out that when I connect the phone, under my computer appears two removable disks.... if I turn on the usb connection, only one transforms to usable removable disk (internal) and the other one asks to insert the removable disk. I used the same sd card on my HTC desire with CM nightlies and it worked perfectly... could it be CM-s bug?

Sorry to ask (maby the obvious)
On Your phone.. using your filemanager (Root explorer astro or what-ever..)
Browse to sdcard
Do you have a folder called _externalSD?
On this phone, for some reason the external SD is not mounted under./ but as i said under ./sdcard/ (i.e its mounted under the internal SD card..)
Just a thought

Where the different cards are mounted doesn't make any difference. And as he said, it works with other cards (2GB and 4GB).
CyanogenMOD mounts internal card as /mnt/emmc, and external card as /mnt/sdcard by default.
When turning on USB storage, both cards should be unmounted and shared over USB.

Hi, I had the same problem with mine, and as you said in one of your previous posts, I had to do a format through the phone and as soon as I did that I was good to go.
I did use the same memory card in my old hero so this might have something to do with it... I'm not sure.

By formatting do you mean from the menu Erase SD card? On the desire I actually had the formatting request from the computer, but there was another problem (some of the rom's files were on the sdcards ext or something and I had no access to the card from the USB).... kind of a similar problem if I think back now but after changing to CM, the problem disappeared.

I forgot to mention I am running completely stock rom and unrooted (for the time being) and there is just an option under sd card & phone storage setting to format external sd card

After erasing the sd card from the phone, the computer recognized it i'm currently copying stuff back and i'm pretty sure it does not affect the recognition

I faced the same problem. I had Swapper2 on my NC, and after I uninstalled it (and cleared the data of Swapper2, just in case) everything went to normal back again.
^ a solution.

[Q][SOLVED] Internal SD not recognised

I'm a bit of noob to all this, so please bear with me.
I was previously running Modaco FR19, when yesterday I decided I'd finally jump to GB and installed CM7 nightly 204 using Paul's kitchen. Everything is working fine, except that my internal SD seemingly isn't being recognised. Any time I try to launch my Gallery or ES File Explorer, it gives me the message "SD Card unmounted or not present". When I go to settings/storage then it shows up normally as '/mnt/emmc' and will let me unmount or erase.
External SD card works normally when I put that in, but I'm used to leaving it out as I never use much storage space.
Another funny detail: when I connect the phone to Windows via USB then I'm not given the option to turn on USB storage, however that option appears if I do it while the external SD card is inserted. In that case, the internal appears as drive H: and the external appears as drive G:.
Can anyone tell me how to fix this? I didn't look into if CM7 and FR19 have different file systems so I don't know if its to do with that. Or would a wipe help? Would appreciate any help.
Cheers.
edit: With ES File Explorer, I can still browse to the internal memory and it will display all the files as it normally would. Do I need to change a pointer to the default storage location somewhere? As my gallery still won't find my photos.
edit 2: I changed an internal storage setting in CM, and then later moved some of my photos to a different folder, and everything seems to be working ok for the moment. If nothing else is screwed up, then I'm good.

Hello!
You could also try using "stock mount fix" for CM7...

I would prefer to install a external SD-card since they aren't really expensive any more...

Thats pretty neat, I didn't know about that, thanks. I'll give it a miss for now, as I don't want to risk screwing up my phone even more.
The only reason I haven't been keen on using an external SD card is because mine is only 2gb, compared to the 5gb+ that comes with the phone internally. But looking at prices, I might just go ahead and buy a bigger card to use.

[Q] Lexar 32Gb micro SD Card HC Class 10

I have the above memory card for my N7000 (Rocket Rom v3) and am having problems verifying its capacity.
H2testw (Windows utility) verified it as having no errors and as 32Gb
ES File Explorer's SD card analyst displays capacity as 11.06Gb
SD Tools displays capacity as 11.6Gb
I have tried copying music (21Gb) to the sdcard using two methods. Firstly connecting the phone as a media device which was very slow and started to throw up errors after a while. Then secondly by removing the SD card from the phone and plugging it into my laptop (Win7) which was far quicker. This second method didn't throw up any errors BUT when I put the card back into my phone no files were found!
I am beginning to think I have a fake SD card which when plugged straight into my laptop is telling it 'Yes I'm a 32GB card' but for some strange reason allows it to copy too many files to the card without complaint. I am going to do some tests to check this out.
In the meantime is there an alternative utility which is guaranteed to verify what my card is either on Android or MS?
Thanks

Please try to do a SD card format on your laptop before putting it in your phone
It might be an issue with its storage that is preventing android from detecting the full size
If that didn't work, try to format the memory card over the phone (using settings)
Best of luck

Okay there were 2 problems, the first one was getting the memory card to be read by my note which I've now managed to do, not sure what I did but there you go, but it certainly wasn't reading before.
The second problem and this is a little embarrassing but when ES File Explorer opens up it displays the contents of the "/sdcard/" by default which on my old desire was the external sdcard but on my note its the internal memory! Not the external sdcard! To view the external sdcard you need to navigate to "/storage/extSdCard/" which is downright misleading unless you come from a Unix mindset of course
SDTools just seems incapable of picking up the external SD card and can only see the internal memory.

Micro SD Card Data Recovery?

So.... I always backup my things, but my friend not so much and well all the sudden he was asking me why there where hardly any pictures in his gallery. Well the micro sd card was not being detected so I put another in and it reads it fine.
Also put the Micro SD Card into my PC nothing at all even under storage devices, it detects the adapter is plugged in but as if there was no card in the SD to micro sd adapter. Also placed it in several other phones nothing like its dead.
I`m not getting the error like people have where the card is detected but corrupted, This card reads not at all! If it was "courpted" I have data recovery software for that ive used for people in the past, but this card seems dead.
Anything I can do? It has a ton of family pics etc on it which cannot be got back. I know the data is most likely there as there has been no physical damage to the card or even the phone.
I have also tried cleaning the cards contacts.
Any suggestions? Its a 8GB Samsung Micro SD card.

Hello. I suggest Recuva ( https://www.piriform.com/recuva ). Run it with your PC and use Admin rights. Deep scan your sdcard. You maybe able to recover files then, if the files themselves are readable and not corrupted. I have had these file corruption problems with cheap ebay sdcards wich at the end appeared to be fake/counterfeits.
I also suggest to format sdcard exFAT and run h2testw ( http://www.softpedia.com/get/System/System-Miscellaneous/H2testw.shtml ) to sdcard with PC to see is your card faulty.

You will need some specialist recovery software. We were recommended a program called ZAR. Other similar programs are available, but ZAR worked well for us and is free for this purpose.
Install ZAR, then insert the damaged SD card into your PC's card reader. Launch ZAR. (You may have to disable your PC's security software, in which case we recommend you also disable the internet connection).
When prompted, click the Image Recovery (Free) option. This will help you to recover photos from an SD card.
ZAR will now look for devices that are installed, and you need to point it to the offending SD card. Select the correct disk and click Next. ZAR will now analyze your SD card. This will take a few minutes.
Once this is complete you'll see a list of the recovered files. On most SD cards the chances are that clicking the 'Root' checkbox will select all the images. Click Next and you can then select the folder into which recovered files will be placed. By default, this will be the same as the folder you chose to save (so 'Root', in all likelihood).
One important point: you will be asked to select a destination folder for the recovered files. Make sure you choose one on your PC's hard disk and not back on to the corrupt SD card. The latter option will help you not one jot!
It will take a few minutes for the files to copy across. Once this is complete browse to the destination folder you selected. You should find most if not all of the files you wanted to rescue.
