Help please. All my data get lost!
I know the data on the card, but just cannot see them.
From checking the property of datacard, i know that all the data still on it. however, after open the card, just 2 files which i never know, all the others gone.
Don't know what my trinity did on my datacard wile i using the bluetooth internet sharing with my pc. After that, this happened.
All 1.4GB data disappeared!

sure, it's my pleasure to help others here.
I use wm6 with a 4GB MINI SDHC(Karmba 4.0). After i use bluetooth internet sharing with my laptop, i found that all 1.4GB data disapeared from my sd card. Instead of them, i saw 3 files which have strage name on them and cannot be opened. All these files are 0byte. Then i insert sd into my laptop, right click sd to check property, i knew all data still on sd card, because the property of sd card shows "1.4GB used". After that, i enable my laptop to see hiden files, not see anything from sd card again.
Finnally, i found a tool called "Final recovery". This tool bring the most of files back to me, not all of them.
I suppose, the internet sharing write all the internet temp files into my sd card, then all my data had been overwrited. So, even when i use recovery tool, cannot recover all of them.
Karmba 4.0 set internet cache and temp folder in the sd card by default(Karmba 4.1 maybe does the same thing). Thus, i think maybe this is where the problem comes from.
By the way, i really appreciate what Karmba did for all the user here. His rom is quite good, But i think 1.2 is the best one. The others really need debug.
Hope this information can help other people who have the same problem. Cheers.

It's nice for you to share about your experience regarding recovery.
However, I think it's worthy to point out that SD corruption could be caused by almost any program that access the card. It has been discussed many times in the forum.
It's actually a HTC bug, which goes unfixed. Artemis got a fix to its SD driver long time ago.... Anyway, prevention in my opinion is far better than recovery. Look for a program called "sdsentry" and it will notify you when the corruption occurs and allows you to reboot the machine to prevent the corrupted FAT image got written to the card itself. It will save your day. Try it.

Sprint update - SD card problems

well I updated to the new rom without a problem I backed everything up on my 8gig card and removed it prior to installing the new rom, now that I put the mem card back in the phone for some reason it shows up as empty? what is going on here?
*update* I just checked in settings to see if any space is being used on the mem card and it shows the space as used but nothing is physically visible on the card

if it turns out that I lose everything on the SD card this was he worst thing I have ever done, might as well throw the phone in the toilet and call it a day all contacts gone! all photos, 500+ songs and spreadsheets. Although it does show the space as used on the card (hope that is a good sign!)
someone please help

Try this. It's a demo version but it may save your data.

Thanks! I will give it a try

I'm having the same problem. For me each time I experience this, I just remove the card then reinsert it. It usually recognize the card after that. Just a hassle to have to do it each time it happens though. I've been searching other post to see if I can find a solution, but nothing yet. When I do find something, I'll post the solution for you.

Thanks I recommend staying away from the program guitardoc64 posted, I took about 4+ hours for it to scan and find my data then when you go to save it you have to buy it first and the price is rediculous $69.00
"Data Doctor recovery memory card"

My bad!!!
Sorry about that! I posted the wrong program! In my search to find recovery tools I had downloaded about 10-15 different ones and well...got in a hurry to help, and can't apologise enough. I can fix my mistake at least, with the PCI file recovery program.
This one is freeware, works very fast (tested by recovering files my Touch screwed up) and I really wish I'd posted it instead.
Damn, tried uploading and it didn't work. Here's the link.

No problem you were just trying to help and I appreciate that! Luckily I was able to retrieve most of my files minus a few programs and songs

These problems are on the new ROM?

somehow the files on my SD card were corrupted when I put the card back in, so I'm not sure if I can attribute it to the rom

It may not be the rom... over at PPCGEEKS they've been talking about the microsd cards getting corrupted for what seems like various issues. I ran into the same problem awhile back and I can't remember where I spotted it but, it mentioned reformatting the microsd in FAT as opposed to FAT32. I did that and I have not had any problems since.

Its' not format specific. I have had the problem with the card formatted both ways. The Artemis SD .cab improved things but I still get problems, so far a soft-reset has been fixing things. I'm looking at the Diamond coming out in Sep on Sprint as a replacement. Don't get me wrong, The touch is 99% of what I expected it to be but the SD issue is a big disappointment. I never had issues with my Apache other than it's clunky size and the fact that it looked like a BBC sci-fi prop.

[Question] Are there two disk drives or something?

**Disclaimer so that this doesn't get deleted. I looked at all the posts and tried to search, couldn't find any answers and I made this thread HERE because I doubt anyone in "General" would know what I'm talking about. This is more of a development question.**
----------
Ok, I am actually having two problems.
1) Normally when I plug my phone in the computer and choose "disk drive" mode, a screen pops up on my PC titled "Removable Disk (J)" That's actually not the right one because right behind that screen I get another pop-up titled "Removable Disk (K)" and that's actually the one with the folders and everything that I'm supposed to use (the root of the sd card folder.) So I hit cancel on (J) and am on my way using (K).
Well over the weekend, on Friday, I rooted my phone using toast's way and then I went camping without doing ANYTHING else.
Then I come back last night, everything is working fine and I installed ROM Manager on there because I wanted to flash Pete's "BuglessBeast". Since my internet connection in my basement is super slow I decided to just leave it at that and work on it at work today. Well here I am.
Problem: Phone was not connecting to computer. It kept giving me errors and then asked me to Format my card. After about half hour of trying to get it to connect I said "fine.. I'll just format it and factory reset my phone and root all over again and do all this. Well now.. phone is only connecting to (J) drive. (K) never appears.
2) Also, after rooting and finding out that ROM Manager won't work for me I have to manually download the file, I tried to go into recovery mode and every time I selected "sd card: apply update.zip", I keep getting the same error saying "FILE NOT FOUND ON SD CARD".
Any help please?
Am I doing something wrong?
Is there a way to start over, all over again?

With the problem running (where you can see both disks), right click on "My Computer" and select "manage", then go to "Disk Management" and see if your SD card is partitioned or something. That's very unusual and should only present itself if your SD card is partitioned and it's seeing both partitions.

development is not for posting questions, q and a is for posting questions (hence the name)
you probably built an ext container before (partitioned the card, using one of the recoveries). if you partition the card, they will come up as two disks when you plug the usb in. when you 'repaired' it, it formatted the whole thing into one block. by formatting, you've erased anything you had on it. you'll have to put the files you want back on the card.

ive seen quite a few windows users on here name their file update.zip but have hidden file extensions turned on so in reality the name is update.zip.zip which will not work.
if thats not the issue, something sounds very wrong with your microsd card.
not sure why you had two partitions, J and K, but seems to hint at app2sd or had two partitions setup on the microsd card ...
my friend had one go bad on him yesterday, i had never seen it before but perhaps there is something defective.
otherwise, a reformat of the card, should bring it back to new.

[Q] Flash a ROM without an SD Card

I've searched for quite a while and can't find a thread on this, think I've managed to find a fairly unique problem!
Following a recent screen replacement (entirely successful apart from the following problem!!), my DHD is not recognising my SD card. I've tried a factory reset and fixing the permissions through CWM recovery.
I have also tried the SD card in another DHD which recognised it no problem.
I know that this could be a hardware issue due to my fumbling around, but there are several other small glitches that make me think that my rom might be the problem, so I'm wondering if there's a way of flashing a new rom without using the SD card?
Anyone who could provide me with instructions for doing this would be much appreciated!!
Thanks in advance.

Using a file manager, look in /mnt/
Do you see anything in there? i.e /sdcard?
If not then I'd say it was hardware, If you can try another SDCard in it, give that a whirl.
AFAIK, even if you run a RUU~.exe to restore you still need a SDCard as that transfers the rom.zip/PD98IMG.zip to your SDCard.
Not trying to teach you to suck eggs, but have you checked the contacts on the handset? Dirty/Obstruction/etc....
Suggestions,
1). Another SDCard
2). Finding a suitable RUU for your device & running (Search the DHD Dev forums for the RUUs).

Ok i've had a look in Astro.
Firstly I get a little error message saying "Error creating external cache".
Looking in /mnt, there are 4 folders: /asec /obb, /sdcard and /secure
All of these folders are empty according to Astro. If I attempt to create a new folder within any of them I get an error message.
Have turned up a new issue too - the usb connection is intermittent. It will sometimes give me the option to choose the connection type, but at other times it will just charge the phone. I've made sure I'm using the correct cable (i.e. one that is capable of data transfer - not just a charger!)
Have also tried someone else's sd card from their phone that I know is working and no joy.
Thanks for the suggestion about contacts, I hadn't thought of checking that to be honest. I seem to remember reading somewhere that the phone will not access the sd card if the bottom cover is not on properly (the contacts are not seated correctly?) - is this something I should check or have I made it up? I'll have a look at the sd card slot this weekend and make sure nothing is causing problems.
Will also do some research into RUU.
Thanks again for your response, much appreciated!

Problem solved! Seems it was to do with the back covers not being properly aligned.
Phew! Thanks for the suggestions.

Hello mshipway
I have the exact same problem. It also came after screen replacement.
Could you please describe hos to fix it?
Thx in advance

Writing to externalSD...

I'm having issues that I cannot be sure if its affected by Googles dropped support of writing to externalSD or not.
When I hook my phone up to the laptop via USB I do this to transfer music to the micro externalSD, which is 64GB card, into my Music folder. The first thing I do is make a new folder on it to label the folder by band name. When I do that it just sits there idling and won't change names from New Folder to a band name folder. Same thing happened when I tested another way by just dropping a music file on it. It just acts busy and never processes the transfer.
The only way I've gotten it to work was taking the micro externalSD card out of the slot of the phone and putting it into the bigger card then insert it into the laptop and do my work that way. It works that way but I can't tell if its that KitKat issue that's affecting it or its something else.
Has anybody been transferring files via USB or doing what I do?

If you use the Samsung Kies application, it works. At least it works for me using Kies. Haven't tried just using the file explorer.

The external SD restriction is only from within the OS itself. It only affects third-party file managers (or any app trying to modify files on the external sd). Doing anything on a computer should work. Something is wrong with your phone.
I've had this happen when my devices' OS gets messed up. Factory reset (or reflash when I was using custom roms) usually fixes it. I don't know the details, but something with the way the phone presents its storage to the computer gets messed up.

I only hit the idle if my phone screen is off, if I keep it awake it writes like a charm

Yeah and file transfers will slow to 0kb/s and eventually (after a long time of waiting) the computer will say something about the device not being found. Right?
This is what I was saying. As long as you aren't running a custom rom (which you can't on the n910a), then a factory reset SHOULD fix it.

If it works for you then do what you're doing. If it gets worse or something, try my suggestion though. It should fix it, but yeah, factory resets can be annoying.

Yeah titanium backup would make it a bit nicer, an icloud style backup would be a godsend

I'm the OP of this thread, lol. Anyways. Did a couple things to test out ideas.
One... Kies... I hate it. Sorry asjshenry. Thanks for the advice though.
Two... tried a different Samsung USB. Same issue.
Three... I may have done something wrong last time with this but when I dragged and dropped a file into the micro externalSD via USB it worked fine. No idling or freeze up. I stated it did this the first time I tested it but I may have done something different than I thought I did.
Four... while still using a different USB I went ahead and tried to create a folder and name it. It just hung there idling.
I guess my last resort is factory reset. I'd like to think it isn't the phone but maybe Windows 8.1 just not playing nicely with the Note 4. A lot of weird things have happened on 8.1 including my Bluetooth mouse not working anymore 4 days after I bought it. It stopped working after Windows pushed an update. Not really sure but I have noticed odd behaviors from 8.1.
I'll try factory reset tomorrow and report back. If its the same issue still then its got to be something with Windows.

OK so I finally got around to factory reset and tried again. Still having same issues. There must be some kind of syncing error with Windows 8.1 or something. I don't get how it will allow me to drop a file in (i.e. a song) without issues but it will not allow me to create a folder and name it.
Only way I can do this is by taking out the micro SD card and put it in the bigger card and then into the laptop.
It gets annoying doing it that way because of having to take the case off then back door then the card and then put everything back together again.

If you have 2 laptops or PC could you test this problem on a different one and see if the problem persist? I actually have 2 laptops but the screen on the older one got fried so I have no way or seeing if its a persisting problem.
I will also make some time tomorrow and see if I can speak to a geek squad rep or Microsoft rep online and see if they have any suggestions. I'll have to speak to them about other problems that I see coming up with each updates they push out too.
If I can't get anywhere with fixing all these problems then I will be converting the laptop fully to a Linux OS of my choice. I'm not liking anything at all with windows 8.1 and this laptop is barely a year old.
Also its interesting that you said you had the same issue with the S3. I have the S3 too here before I got the Note 4. I didn't see this problem with the S3 on this laptop and it has been awhile since I had the S3 hooked up to that laptop to transfer music over. That's what is leading me to think that an update broke stuff.
I'll update this tomorrow if I get anywhere.

Sorry it took so long to reply, I took the 5.0.1 update recently and tried creating and renaming a folder on my note 4 using my windows 8.1 machine, I got the same result, folder was created but windows explorer hung and crashed during renaming the folder. I tried it again on my windows 7 machine and it successfully created and renamed the folder without any hiccups. also its worth to mention that i do not have usb debugging enabled, and every time I connect my phone to the windows 8.1 machine I get a usb connected sound and then a second later I get a usb disconnected sound and then the windows explorer window showing my phone and external SD

Thank you. That confirms my suspicion that it is within Windows 8.1. Debugging is not needed for anything.
I had to dig deep to figure out the problem,and according to an article some updates plus components become corrupted without our knowledge. Only way we know something is wrong is one thing after another stops working (i.e. my Bluetooth mouse, writing to external SD, etc).
There is a fix for it as long as it can complete it thoroughly. If not then a fresh install of 8.1 is your only last resort.
This is what I did from this link...
http://www.eightforums.com/3407-sfc-scannow-command-run-windows-8-a.html
Right click on command prompt to grant Administration rights. Click ok. Command prompt will open. Run this...
sfc /scannow
Wait for it to fully scan.
Mine said it couldn't fix all problems. I had to go to Dism /Online /Cleanup-Image /Restore health link...
http://www.eightforums.com/26512-dism-fixing-component-store-corruption-windows-8-a-8.html
This will take awhile and look like its hung up at 20% but let it finish.
My results were...
Error: 0x800f0906
The source files could not be downloaded. Use the "source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243007
Had to go to that link and was lost on what to do. So I read through the forums for similar error code by others and the author recommended to do a refresh of Windows or do a complete reinstall of Windows to correct the problem and run sfc /scannow to confirm all is good after reinstallation.
This leads me to believe several updates became corrupted and a lack of a component store. I have no clue how that broke and it's all on Microsoft for that mess.
My last resort is now to reinstall a fresh copy of Windows 8.1 to correct all issues. It's going to be a pain in the are with all that stuff I have saved on the laptop and backing up everything.
Check out those links and run them to see if your stuff gets corrected. You may have better luck than I did and if you do then reboot after all that and test the external SD issue.

Right click on command prompt to grant Administration rights. Click ok. Command prompt will open. Run this...
sfc /scannow
Wait for it to fully scan.
Mine said it couldn't fix all problems. I had to go to Dism /Online /Cleanup-Image /Restore health link...

This will take awhile and look like its hung up at 20% but let it finish.
My results were...
Error: 0x800f0906
The source files could not be downloaded. Use the "source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243007
Had to go to that link and was lost on what to do. So I read through the forums for similar error code by others and the author recommended to do a refresh of Windows or do a complete reinstall of Windows to correct the problem and run sfc /scannow to confirm all is good after reinstallation.
This leads me to believe several updates became corrupted and a lack of a component store. I have no clue how that broke and it's all on Microsoft for that mess.
My last resort is now to reinstall a fresh copy of Windows 8.1 to correct all issues. It's going to be a pain in the are with all that stuff I have saved on the laptop and backing up everything.
Check out those links and run them to see if your stuff gets corrected. You may have better luck than I did and if you do then reboot after all that and test the external SD issue.

I ran sfc /scannow and it failed verification and didn't fix anything, so then i ran dism as you said however I used a bat file I had instead, and it fixed whatever sfc was complaining about. If you want to try it copy this into a notepad and save it as a .bat file and run as admin
Dism /Online /Cleanup-Image /StartComponentCleanup
pause
Dism /Online /Cleanup-Image /RestoreHealth
pause
SFC /scannow
pause
since sfc passed I ran windows update and took all the important and optional updates, restarted and ran sfc again and it passed again. I plugged in my phone and created a folder and tried to rename it and as always explorer hangs again, and crashes, without unplugging my phone I go back to where I created the folder and tried to rename it and it works, problem is if you unplug, explorer will hang and crash first every time before working, also this method doesn't always work, for example sometimes external sd disappears from the list, other times when you click on it, it brings you into phone sd instead of external, and lastly another bug I've noticed is that the language changes after a crash on the list of available memory, there were a couple of instances where everything was replaced with Chinese or Japanese characters. I hope this was helpful but I doubt this problem could be fixed, unless windows 10 fixes it we're going to have to deal with it
