In the last couple of weeks, whenever I try to transfer either a single file or large groups of them (from 64-bit desktop windows 7 pc). Nothing happens on the streak side, but on the pc side, I keep getting a message that says disk locked or write-protected, and that I either should unlock it or use another disk. This problem began when I started experimenting with futambool and/or missing link, I think. But maybe not. Anyone have any ideas?

I should have added that I can install free and paid apps perfectly well. My only problem is transferring docs, etc.

Apps usually go to internal storage. When you copy from your computer to the phone mounted as a USB storage device it is going to the external sd card.
Try removing your SD card and connecting it to your computer with a card reader/adapter and see if you can read it. I suggest backing everything up if you can and reformatting it. You may want to try the formatter provided by the SD Assoc.
Marvin02--thanks! I'm on my way. Will report back in a few hours. Thanks again.

OK. It seems that, despite the fact that there is no obvious lock on a microSD card, the card was locked. Apparently, sliding the microSD card into an SD card adapter (in order to slip the card into a card reader, may move the SD CARD'S tiny lock, thereby somehow locking or unlocking the microSD card. Somehow, even though you remove the microSD card from the SD Card adapter, the microSD remembers the state the adapter left it in (by setting or unsettling a bit flag? Or maybe the adapter physically moved some submicroscopic plastic particle on the microSD card?)...anyway, the only way I found to change a microSD's state is to put it back into the adapter, put the adapter into a card reader, and run the microSD card from your desktop computer.
If you Google this problem, you'll discover that suddenly write-protected microSD cards is a fairly common problem.
Marvin02--i didn't try to reformat my card, because I'm the superstitious type and I didn't want even to breathe on the microSD card once it started working again. But many thanks, because you led me to a solution.

Last night just before plugging in my beloved SGS2 I saw that there was an icon of a microsd card with an exclamation mark on it. The phone was complaining that the card was corrupt and unusable.
Card is a Patriot brand Class 10 16GB (Yeah, I went with a cheaper model). The file system was unusable and unreadable when I tried to read the data with a micro-sd to SD adapter on my PC. I was not able to retrieve any info.
I switched to an 8GB Sandisk card from a previous phone, but am concerned now about losing data again.
Has anyone else encountered a corrupt micro-sd card on their SGS2, or a similar problem with a Patriot brand card?
Thanks!
I was facing the same problem too. reformat it and it will work again....
however the micro sd getting corrupted every month.....
now sending it for rma...
Corrupt Micro SD
I have the same problem I formatted it with my sgs2 but now I think mine is worse, my 16gb micro SD card says it has 0 bytes in windows and therefore is to small to be formatted and in osx and ubuntu it says it has 2.2 tb and has errors and cannot be formatted.
It freaking happened again! Different card now, bought a 32GB class 10 on boxing day. Just a fortnight later I've lost all the files from it!

Have you tried just taking the card out of the phone and just connecting it directly to a pc with a card reader? My card use to become corrupted when a file transfer went wrong on my phone, but I just remove it and plug it in directly to my pc and it goes back to normal.
The first time I did, couldn't be read. Keeping backups for now.

Okay. Got a new phone and the sd card won't recognize now. Worked once til a reboot then it doesn't show up. Can't mount or unmount. Is there anyway aside from factory rest to get it working?

Before resetting the phone try and see if your computer recognizes the card, and if it does reformat the SD card. If not, return it, you probably got a dud.
It worked before on the old SGSII. But not on the new one. Odd. Bit I s'pose it is possible

It seems like andoid plays best with cards that are in fat32 format with 32bit sectors.
I may be wrong on the sector size. Please correct me if I am. Can't find where I read that.
If you can get the card setup that way and the phone still has issues reading it, it may be the new phone.

I can't get the card to recognize on the computer, I don't have a micro SD adapter though, this was in the phone. But I know it isn't the phones SD slot, as I tried the card outta my photon, worked fine. And tried the bad card in my Photon, and nothing.
So I suspect the card is bad, just not sure how it got messed up. Still strikes me as odd. But stranger things have happened.
Sd cards do have a way of acting up in weird ways.
I would hang onto the card until you get a chance to plug it straight into a pc. Linux is best for being able to read/fix messed up partitions.

I've just bought a 32gb micro SD card and put it into my phone. It appears to be faulty but the reason doesn't really make sense.
When you move something to within a folder it automatically gets deleted somehow almost straight away.
However, when you move something to the root of the card it stays.
I can't see how this can be possible, any idea what's going on?
Hey there Bennji,
I have come across this problem where my if i deleted something from my MicroSD card, it would reappear if i restarted the phone. It could be related since I tried deleting the file when it was in a folder. I formatted my MicroSD card on a computer (Not Android since it might be the cause of the problem). Just format with the same settings
Hope this helps!
Can't it be formatted using my phone? If it can be, how because I couldn't be bothered messing around with windows.
Many thanks

OK I'm at a loss. I've searched for this issue and haven't seen anybody else experiencing this problem.
My Evo is relatively new. Had it just about a month now. Still stock. Haven't had any real problems until I bought a 32GB SD card. I've purchased 2 actually and have had the same issue with both. The phone reads the card fine supposedly. Shows 32GB available (just about). But I'm having the HARDEST time copy files to the card. I've got a ton of music, pics, ringtones, etc I'd like to get on this device. I can connect the phone to my PC, mount as a disk drive and copy to my heart's content. But then when I disconnect the phone and try to access some of those files, they're gone. I mean just GONE. The entire directory I just created with all of it contents... GONE!! Not misplaced or deleted by accident. GONE like they were never there. Like I didn't just spend 10 minutes copying 2gigs worth of files. And this happens just about every time I try. I unmount the phone properly, see the message on screen "preparing sd card" and all seems fine. But my music player says there are no files. Gallery is empty. Go back to look for the files I just copied on the card and nothing. Nowhere to be found. Now of the few hundred times I've tried this now, the directory actually stayed put a couple times. I was able to view my pics, or listen to my music. The folders stay right where I put them. But guess what. The next time I try to copy more files, my directories will disappear again. I've tried 2 different brand SD cards with the same results on both. I've used both Astro and ES to view the cards but it doesn't make a difference. I've even used and external card reader and copied files directly to the card. Still no luck. Please help. This is driving me crazy. Could this be a problem with the phone itself? I don't get it...
Well if you have used an external sd reader without success then the problem is not your phone. Your saying if you copy files to your sd,you cant see them after? So it doesn't copy from an external reader?

I strongly believe the problem is the format of your card or your computer.
If you are transferring files from your external sd reader and if its still there when you check,but gone when you insert it in your phone. Then I also strongly believe that you are looking in
/sdcard directory which you should actually be looking at /sdcard/ext_sd/

I'm saying that no matter if I use an external card reader, SD adapter, or connect the phone directly with a USB cable, the files I copy to the card will disappear "magically" once I dismount the card from the PC and attempt to read on the phone. Usually this is the case. But like I said, a handful of times, the files were where I put them, but disappeared the next time I tried to copy more files to the card. And no I'm not looking in the wrong directory. I know the difference between the sdcard and ext_sd folders.
What brand of cards are they? Do you have the same problem with cards of a smaller capacity?
Sent from my EVO using xda premium
This looks like a problem with your computer settings. With some configurations, if you don't explicitly eject/unmount the drive from the PC, it won't actually move the files. It will only truly copy them when you begin the eject process.
I tried a Kingston 32GB class 10 card first, then bought a generic 32GB class 10. Same issue with both. I do have a smaller 8GB SanDisk class 4 card that I have not tried yet.
I made sure to "safely remove" the cards when connected to the PC. I've tried from both a desktop and laptop. Same results all around. I thought maybe the problem is with class 10 cards but I haven't heard anyone else having issues. I also thought to try a 16GB card. But that would suck since other folks are having success with 64GB cards.
I'm about to try to reset my phone and see if that makes any difference. I may be headed back to the Sprint store this weekend.

Where did you buy these cards? This seems like a fake capacity card symptom to me. Try copying just one or two songs and see if they stay. The cards are probably fine but this is something I ran across with a friend's card before who unfortunately turned out to be a fake. I hope it's not the case for you. Also (since the cards seem to be empty for you) run this to be sure the SD card is genuine.
If you actually bought it from a reputable source, then my bad but it's best to get all bases covered.
Now if the above is not it and you had the problem with two different cards, then the issue (probably) lies with your computer/transfer cable. Try doing the reverse, copy some things on the card from the phone and try to read it on the PC. If you need something to copy you can always copy the ringtones that come with the phone at /system/media/audio/ringtones.
Let me know what you find out
I seem to recall issues initially with 32g cards acting up, but I thought only if they were a certain class but could be related? Try the 8g you have. I had issues mounting the 32g I had, class 4 I believe, when I was still on stock. Sometimes it would mount, other times it would dismount for no reason without any warning. I would just know bc I couldn't access any thing on it.

Make sure the cards are formatted Fat 32 to begin with. And yes, definitely try the smaller sd card you mentioned.
Are you sure your looking in sdcard2 and not sdcard when in a file manager?

OK well here is an update.
It turns out the generic 32GB class 10 card was defective. Was able to verify that with the test utility racer posted. Thanks for that btw. I'm running the same test on the kingston card to see what it says.
I also did locate my 8GB class 4 card and that worked like a charm. No problems copying data to or from the card and definitely no disappearing directories. I just want a larger card. LOL. Hopefully the kingston one is ok after I format and test it.
I was putting music on my P769 and when I tried playing the new music, it would say it was a unsuppoorted format, it wasnt, it was a mp3. I tried other songs that I knew that would play and none of them worked. I then restarted th app and a song would play but once I tried another song it would do the unsupported format message again. I then restarted the phone, the phone then gave me the message in the notification area saying "Blank SD Card or Unsupported file system." I then tried mounting it, with no avail, it still wont work. I then factory reseted my phone and formated the SD card, and still that same message comes up. Also, before(and after) the restart, I would try to unlock the phone by pressing the power button the screen would start t turn on but automatically shut off, or it would go to a "snow" screen, but grey. Please help I need the SD card because of this phone's microscopic amount of memory!
I forgot to add that I tried the SD card in another phone and I had the same issue...
Get a new SD card. I had similar problems with my 32gb card when I got the phone. Bought a new class 10 16gb card and it works flawlessly.

Mine is a 32gb too... I'm glad I got a good deal on it...
I did hear of other people fixing it... Or just restarting their phone multiple times... But the other problems happened right after... I was thinking that it may have been something malicious?

I got the 32gb card for like $9 on black Friday around the same time I got the phone. It was flaky right from the start, but worked in my laptops card reader. Made me think it was something with the phone. It eventually stopped working in my card reader as well. Pickup a good class 10 card and everything should be fine.

So just so we're clear, can you put the card in an SD card reader and transfer files to it from a PC? Can you play files off of it through an SD card reader to a PC (or another non-Android device)?
I'm far from an expert, but maybe try breaking the card into separate partitions with something like MiniTool Partition Wizard. The card might be formatted in a way that the phone isn't familiar with. There are a few other threads on the forums that can help suggest what kind of partition would be best for your needs.
I have a 32GB SD card, and it took me a long time of messing with this damn phone to get it to do what I wanted. Card would disappear, messages about "insufficient storage", media scanner freezing up, on and on. This phone has been one huge pain in the ass. Right now I am just using a remount script to swap my internal and external, but so far so good.
Ok guys after extensive searching...I'm having the exact same issues. I did more investigating myself. When I removed the 32gb card from the port I noticed the pins in said port were messed up, the last two looked disconnected. After fooling with it for a min I decided to use the card on my tablet to get files from it, unfortunately the tablet didn't recognize the card at all. I'm thinking my phone corrupted the sd card somehow. I have yet to try another card in my phone for fear of messing another up. I'm going to try to insert the original 32gb card and have it reformat like it's asking and see how it goes. If that fails I'm gonna try a lil 2gb card in it. Also, I've contacted LG and am awaiting a return call for a warranty repair because it looks defective, I haven't dropped the phone recently, and just bought the phone in March from Best Buy... I'll keep y'all updated on my progress and wish me luck lol!

Alright here's my update, I have the SanDisk Ultra 16gb micro SD HC I u (red and grey), I think my sd card is going out as well, but I'm wondering if there might be more to the problem. Yesterday i took out the card and I placed it in my computer to move some file. It didn't pop up at first, I wiped it and place it back in the PC and it started working. Once done, i place it back in my cell and it was working fine. I went into CWM to flash a backup. I was doing some testing so I flashed two different backups. So today i noticed that the Sd card it not mounting, but when I'm in clockworkmod it is working fine I have rebooted and checked several times, it's mounting and operating on my PC & CWM but not when the phone is on. I'm thinking CWM might have something to do with it, not sure (might be a system restore). I was going from 4.0(ice) to 4.1(jelly) & back to 4.0. I'm currently restoring one of my jelly bean backups to see if the problem is solved.
Update:
my L9 is back on Jelly Bean and the SD card is working, it might have been a corrupted backup (or something went wrong with cwm). Md5 is good, but it's not as accurate as SHA-256 checksum. Y'all might want to check if your SD card is popping up on CWM.
Good info.
this is a problem that occurs when we upgraded from ICS to JB. once I upgraded my d card would not work. So I took it out and formatted it on the computer. Then I partitioned it with a program I have and it worked. JB and ICS having trouble with the sd card. If you go back to ics then don't reformat our you work have tip reformat when you flash jb.
