Memory Card in S4 doesn't like Camera Shot Videos? - Galaxy S 4 Q&A, Help & Troubleshooting

I have a Galaxy S4 with 64 GB Sandisk micro SD card. Recently while trying to move a few apps to sd card, the phone rebooted. After that the memory card went bad. I was able to read all my data from it but can't format or delete anything from it. Tried even on my laptop, files can be deleted but after you remove and reinsert they magically come back and anything new copied to the card is gone. I backed all my data from the card and sent it to Sandisk for replacement. Today I got a brand new sealed card from Sandisk as replacement. I started moving all my data back to the card from my laptop's card reader. All my music and videos copied just fine and all other docs, images etc copied fine as well. But when it started copying Camera Videos in the DCIM folder it hanged. I restarted the laptop and tried again, it copies everything from anywhere fine but again at the camera videos the transfer rate drops to 0 b/s and it hangs. Same thing happens when the memory card is in the phone and I connect it via usb cable. Finally I tried copying all the camera videos 1 at a time and this time it went fine with hangs a few times. But finally all videos are on the card and readable. Can anyone tell me whats wrong and where ????

Someone please reply ??

HD2 destroyed my SD card?

Hello.
After trying the android booting, for 5-6'th time (all working), now the phone can't see the SD card. I thought it was only on the phone, but when i insert the card, in adapter and connect to pc, then NOTHING happens. Like if the card wasn't there.. Hmm, any clue? Usually I just formatted. But now, I can't format a SD card which "isn't there."
Please.
any one??? :S

Sounds like your sd card maybe corrupt, they can die for no apparent reason, its happen to me twice in about 4yrs, tho i always buy from CEX they offer a 1yr warranty & just replace it if its within that time.
There's been a few threads about this;

What is the brand of the memory card?
hey dude,i got the same problem as yours few days ago..cant do much abt it,i just buy a new one..some says the htc that makes the sd card problem
Hi,
My 8 GB sd card lags when i`m scrolling in the file manager.
In addition, the sd card drains the HD2 battery. I loose 35% in 6 hours in flight mode, but only 4% when not in flight mode without the sd card... ( this also yields for the original sandisk 2 GB sd card that was supplied with the phone).
Anyone experienced the same issue?
Is this hardware or software related, and can i fix this myself?
Error check your microSD card using your computer then switch your phone off, put the card back in it and switch your phone back on. The phone will need to index your music/video files etc so go to the relevant tabs and let it do its stuff. See how that helps.

i got a new HD2 and it came with a MicroSD card. I put a couple of cooked ROMs on it and everything was fine for about a week and then the card jsut stopped working. I didnot use it on any other phone or on my PC and it just died.
I own an HTC Hero as well and i put the card in it but it wouldnt recognize it. It has never happened to me before. Never has a card died on me.
I think its a problem with the way the HD2 accesses the SDcard. I wouldnt know specifics but this is the first phone that fried my SD card.
Hey guys, I had the same issue. The SD card stopped working and cannot be formatted now via computer.
My experience with Windows Mobile is that the SD/CF driver is the weakest link. The problem seems to be simultaneous accesses drive it bonkers. I've had the disappearing card problem on other PDAs but usually removing it, doing a reboot with it out, and then inserting it after the reboot is complete will fix it. If it doesn't show up immediately DON'T do anything for a while, it could be doing a CHKDSK on the card, and if you mess with it it will screw it up worse.
Once it shows up what I would recommend is hooking up via USB in CF Disk mode (not Activesync) and doing a format on the drive from Windows.
Last night I got a new 32gb Class 4 MicroSD from China (unnamed) and stuck it in, worked fine, so I backed up all my data to my 'puter off the T-Mobile Class 2 16gb and changed to the new 32gb SD. I started the copy and after a while went to bed.
This morning I got up and it had died during the copy. It was giving me an error on the new MicroSD. It had copied about 75% but was asking to continue or skip. I ended up having to cancel it because it appeared full but it was not. After a reboot I found a ton of FILEXXX.CHK files which indicated it was doing a chkdsk.
Looking at it with SoftWinter.com's Storage Tools the disk was formatted with 512 byte cluster size, way too small for such a large disk, so it was not really out of space just out of cluster nodes. If you have lots of files (I had 10,000) each takes up at least one, even if the file is only 5 bytes. So I reformatted it from the 'puter to 32k cluster size and started the copy over. Seems to be working better now.
Please note that using larger cluster size also will help performance when writing and reading large files as it has to do less directory accesses. Small cluster size is good if you have a lot of small files as it doesn't waste as much space. You lose on average 1/2 the cluster size for each file, as the last node is almost never full.

Hey
i hope for your sake im wrong, but as far as ive been able to find out in my own searching, only san disk has released a 32gb micro sd & its only class 2.
there has been a lot of talk of fake 32gb micro sd's from china, most are actually 4gb re-programed to read as 32gb on your phone or pc, but when you start to fill them with files more than their actual capacity they will only overwrite prev' files & become corrupt.
i actually pick up 1 (32gb) last weekend from a local store, tried to copy the contents of my 16gb, 7gb copied then an error occurred, 2nd attempt 9gb copied but files unreadable by phone or pc, fortunately i always buy from this store & they refunded (£50), straight away, still have 2 16gb cards ive had for about 9mnths with no probs.
there is another longer thread over in the Q&A section, you guys may find some useful feed back over there: http://forum.xda-developers.com/showthread.php?t=646731
Well, the one I got says SanDisk and I have done a full format and surface analysis, it checks out, but I am having trouble writing to it. Not sure what is up with it right now. I knew it was a fake but I thought it was a real fake, not a piece of junk. I hope you are wrong.
I´ve got problems too. I have two SanDisk 16 GB microSDHC cards and both of them are giving similar problems.
I´ve got my HD2 a few days ago and initially I used my old 16 GB card I bought with the X1 (then used with my TP2 and latest the HD2). Everything was working fine initially but then the problems arose. Now I have those problems:
1. Audio Manager has problems reading my music library. iPlay can read it though. Windows Media Player takes a long time building my music library but manages to do that eventually.
2. HTC Album can read my albums sometimes - sometimes not.
3. Resco Photo Manager can read the albums but sometimes it takes a long time to do it.
4. The computer can access the card without any problems after formatting and it seems not to be any problems reading or writing files to it. Installations of cabs stored on the memory card works.
5. Total Commander can access the card without any problems but takes slightly longer time than before to show all folders.
6. Running chkdsk in Windows gives the result of a perfectly working card.
7. The phone is draining battery in an abnormal way with the card inserted.
8. Flashing ROMs from the card worked initially but not any longer. Now it shows the threecolor bootloader screen instead.
The interesting thing is the fact both of my 16 GB cards has the exactly the same symptoms. I will try them in my X1, TP2 and Vivaz later to check out their behaviour.
When I inserts my old 8 GB card (everything made by SanDisk) everything works without any problems. Flashing ROMs work normally etc.
I´m running the Omega XT 3.0 and are using HardSPL3. The 16 GB card has worked perfectly initially with this ROM and HSPL so I don´t think they are related.
The whole thing seems to indicate some kind of "incompatibility" between the phone and the 16 GB cards. It´s like it is unable to handle that size of card correctly. It seems like it "trashes" the file system. My older 16 GB card started to behave badly which caused me to buy a replacement and now that replacement has the exactly the same behaviour.
My 8 GB card is an "ultra" SanDisk card. The troublesome cards are Class 2 cards. I began to have the impression the problem is some kind of issue with Class 2 - because the cards itself seems to be working after formatting.
I have formatted them with either Panasonic SDFormatter and the Format SD application on the phone. Both options gives the same result.

Not good: System freeze now ext SD card not readable...

Strange problem this morning.
I was moving pictures around using Fish Bowl Gallery. The app froze while deleting a picture/photo and had to reboot to get things going again. My phone then now cant read the external SD card. The phone is asking me to re-format.
I've very reluctant to format and looking for advice on what else I can do to fix this without reformatting the SD card.
With my reckoning I doubt there is much more I can do but thought better to ask just in case.
Strange:
I'm in the office so it's hard to use my PC for diagnostics as I don't have Hi Suite or drivers installed on the office PC.
Went up the road an bought a multi card USB adaptor ($7). The PC reads the card fine (which is great as I can now do a back up).
Will play with it a bit more and see what happens.
Maybe I am lucky but...
after backing up the SD card I popped it back in, rebooted and everything is back to "normal".
I had something like that on my card... i had to format it, and worked again, but know it corruptes the files or they disappear.
I runned some diagnostics tests and nothing appear.... no idea of what is happening with my samsung card :S

SD Card Issue in S5

Hello All,
Im Hoping Someone Would Be Able to Help me with an issue....
ive got the samsung galaxy s5 SM-G900I with telstra here in Australia, on the 26th of last month i went to my fathers wedding, i was taking photos on my phone with the camera it spent most of its time on the camera app (once closed itself down prob due to inactivity) anyways after a while it stopped taking pictures.... the capture button on screen was grayed out but i could still see through the camera.... i though ok weird and closed the app down and opened it with the same result... then a popup came up that said "Camera Failed" when i pressed ok the camera app closed.... tried to bring it up again and it was a no go so i decided to reboot my phone..... it shut down properly but never turned back on so i though ok maybe it turned itself off so i tried to turn it back on and got nothing..... i pulled the battery out and put it back in and the phone turned on and the camera was working perfectly fine again so i though oh ok glitch but all good.... anyways i went back to taking and i found that all the pics i had taken that day were gone from the SD card...
it took me a minute to relize that all the photos on my card were gone.... i went to investigate and say that the card wasnt mounted under storage and i though all good again and hit mount and nothing happened.... then i saw a notification saying either an unformatted card or an unsupported file system... i checked in another phone with it and got the same issue and it seemed the card had gone bad, anyway i got home that night and plugged the card into my computer and found that the card was reading up as a raw file system.... so i went stright to data recovery but before the data recovery could finish scanning the card all of a sudden there was my sd card reading up perfect in my laptop... which was weird to me as i havnt seen that happen before, so i backed up everything on my card to my computer and plugged the card back into my phone and it came up with a different error i think it said something about the card maybe being corrupt.... so i put it back into my computer and ran a chkdsk on it and it showed that everything on the card was corrupted..... so i decided to wipe the card and start again and i transfered everything back onto it and everything was working perfectly fine as if nothing had happened...anyway fast foward to monday this week and i went to take some photos and recorded a video on my phone (went stright to the SD card) and i checked it afew hours later because i got busy and i had found that everything i had done that day had corrupted and photos that i had taken about 4 or 5 days ago were also corrupted... images that i had seen to be working fine.... so i backed up my SD card again and though ok im gunna have to buy a new sd card and i redirected the save location for photos back to internal storage.... anyway today my SD card was still in my phone... all of my music is on it still and i was listening to music while i was heading out to the shops.... and i noticed that afew of my songs were playing for a second or 2 then skipping to the next or just pausing and throwing an error about the song being corrupt...
so i put the SD Card into my Samsung Galaxy Tab S and the songs that were "Corrupt" on the SD Card were working fine on the tablet..... so i am wondering.... is it the SD Card or the Phone?
thanks Help would be amazing!

sorry about that.... not the best when it comes to that lol, i just edited it i hope it makes it easier to read
I'm not trying to give you a hard time, but that is still hard to read. If I got the gist of your post, you had a camera failed message and apparently SD card corruption.
There isn't enough information (or maybe it's in the middle of those paragraphs) to tell what happened. Probably just a temporary glitch, but you could have anything from an actual camera failure to a physical SD card defect.
Try clearing your system cache. I wouldn't worry about the failed camera message if it doesn't recur. If it does, search for the camera failed threads, Samsung was providing warranty replacements for some early production camera failures.
If you are searching for photos, see if your phone put them on the internal sdcard (since the external SD wasn't accessible). Otherwise you could consider a data recovery app to see if photos can be recovered from your external SD card.
Is your external SD card bad? We don't have enough information to know yet? Do a search for an app to test the card integrity or you can probably use the fsck command to test the card and correct (if possible) filesystem errors, followed by reformatting and remounting the card. The fact that the card was readable on another device doesn't differentiate between an marginal or unstable card and a sound card. You'll have to test and reformat the card to really tell.

thats ok i know your not trying to give me a hard time on it im sorry that its so dificult to read, ill see if i can try this alittle better
on the 26th of last month i was taking photos for my fathers wedding when the camera stopped working, it wouldnt let me take photos so i closed the camera app and opened it again thats when i got the camera failed message
i tried to reboot my phone but it froze during the reboot and didnt start up again so i pulled the battery out and put it back in, when the phone started up again the camera was working perfectly fine but the SD card was coming up as unreconized file system or unformatted,
i got the SD card to my Laptop and the File System Read up RAW i started data recovery and while it was scanning the card everything started working again and i got all my photos back without the need for using data recovery
put the SD card back into my phone and it read corrupt so i reformatted it and restored everything back into it and the card worked fine,
Fast Foward to Monday This Week and i recorded a 10 minute video at 1GB size and took some photos.... and they corrupted.... no issues with the camera or anything like that.
Today i Was Listening to Music that was stored on my SD Card (64GB Class 10 Transcend) and it skipped a song about 2 seconds into it and another song it tried to play and failed coming up with an error about it being corrupt, ive taken the SD Card out of my phone and put it into my Samsung Galaxy Tab S and the songs that were "Corrupt" worked perfectly fine on my tablet
so im wondering if it could be the SD Card or the Card Reader in the Phone? the System Cache in the phone has been cleared.
Thanks i hope thats helped you able to understand it better and again i am sorry for my poor writeing skills

Thank you for going through that again.
The basic question or mystery that we are trying to solve is why does the external SD card only appear to have problems in your phone and not the tablet? And how can we tell if it is a card issue or something other aspect of your phone?
While it could be some problem with your phone e.g. bent or damaged SD card slot, corrupt driver or other causes.. it would be hard to track down without further hints. i.e. there are so many possible causes that we need to narrow it down.
So it's easier to tackle this by elimination. Lets test the hell out of the card because that is easier to do.. and despite the fact that it appears to work in your tablet, it's still more likely to be a card problem. Why would it only affect your phone and not the tablet if it is a card problem? There are lots of reasons, but just to give one example.. it could be a problem on just one area of the card.. and that happens to be where your phone is preferentially storing files.
If that makes sense so far.. then the plan is to see if we can identify a card defect. So.. grab an app that will check for file system errors (chkdsk, fsck, etc), check partition structure and do extended read /write tests on the card. At a glance perhaps one of these apps: Lewy or Dewy.
Most likely you have some bad clusters which fsck or chkdsk could repair. But it's best to run an extended card test.. that may take a few hours but it's still a lot quicker than trying to search for all the possible causes of phone problems. If your card passes with no issues.. I'd be inclined to back up your phone and then install a brand new, 100% fresh and stock firmware temporarily. That should in one swoop tell you if it is a hardware or software issue. Again, we are looking for expedient ways to narrow down the possible causes.

i will give u a hint ... try to make your topics, in your case, a loooooot less than your post so a lot more people would help you.

Im Sorry it took so long to reply to you, The 2 apps u suggested did not work they wouldnt detect the SD Card, i put it into my laptop and backed up my data and i ran a chkdsk on it and it came back clean said nothing was wrong with it, i have hard disk sentinel installed on my laptop and ive run a surface scan on it that is doing read write read test selection on 2 passes and has been running all day.... the first pass came back clean on it but the second pass has picked up 4 bad blocks near the end of it... its come up "7/08/2014 9:43:09 PM ! Verify error, Sector: 99480300" afew times with different sectors on it, im wondering if the camera issue i experenced could have caused my card to screw up like this? or even the phone not booting back up without taking the battery out first after the camera issue happened? would you consider Transcend a good brand for SD Cards? mine was a Transcend Premium 300X Class 10 Micro SD Card 64GB, im thinking of getting a 64gb Samsung Pro Micro Sd Card now... are those good?
Hey mate! finally i have someone who has the same issue as me! this happened to me last week. i was going through my photos and they looked to be all corrupted. i didnt take much notice as i didnt really need them. i was at the gym and my music was all gone. it was all saved to my samsung 32gb SD card. i got home and there was a message saying SD card is damaged. i lost everything. i did a format and nothing happened. it still said SD card failed.
i went and bought a new Samsung Evo 32gb SD card and it is doing the same thing. i plug it into my laptop it works fine. when i chuck it back into my s5 it says its corrupt. i have no idea whats going on. SD card reader in the phone maybe damaged somehow? i dont i have ever dropped my s5. its driving me mad.
My wife's 64GB card is now doing the same. Formatted and working twice. Images all saved to cloud but a pain waiting for it to happen again.
Ordered a new 64GB card today. Hoping that sorts the issue. If not its return to store time. Happy knox is intact.
Sent from my Galaxy S5 running NeatRom 0X1
my galaxy S5 does not read SD card also..
i think most likely is the software issue.
Just wanted to chime in here. I have a hardware failure with my s5 SD reader, and it was my fault. I had to replace my digitizer, hence putting My Straight talk sim into a temp phone for a fee days.
I cut my sim down to nano size for the temp phone, then stuck the now nano sim back in the s5 after repair, I didn't have a sim converter, and ended up bending pins. Thankfully the sim still works but I toasted my SD slot. Not only will it not read any SD card, it breaks any working one i put in it. I'm a hardware guy, so I'm going to give a go at fixing it, but I'm pretty sure the whole assembly is soldered to the board, no replacing this assembly. At least I don't believe so.

SD Card unmounting randomly

I tried to solve this problem, but nothing gives me any hope. I hope you can save me here, otherwise I sell the phone and migrate to iPhone permanently. 6-7 months ago I bought a 128 SanDisk SD card and when inserted in the phone I formated it as internal storage. Everything worked fine until a week ago (same day when I updated to 7.0), when the card started to unmount randomly (which caused my phone having no ringtones, no pictures, etc.). It is revesable by restarting the phone - it immediately recognizes the card but just for 1 hour or less. This time seams to be longer if you manipulate the card through the phone, if you try connecting it to the computer or uploading files to a cloud storagge - it drops to 1-2 minutes - so you see I cant take my photos out of it. I installed SE explorer and Files to SD Card app - both don't recognize the difference between the original build in memory and the SD card so I can't migrate anything. I am starting to belive that the card might be the problem, as I tried to put in a adapter and then a card reader and it didn't show up in My computer at all (or is this normal, I red that the card is encrypted?). Anyway - I am looking for a solution (prefferably app or build in Android function) that will allow me to migrate my pictures and videos from the internal memory formated SD card to my actual internal memory.

Nokia 5 SD problem

Hi all,
My partner's phone - Got an interesting problem with the SD card. I bought an SD card, 64GB and put it in. It formatted fine and even offered to move the stuff off the phone and onto the card. Happy days. The problem now is, when I delete a file from the phone, it doesn't delete just from the phone, but both phone and SD card... lol. O...k. lol.
So I then sent a test file, a random video to myself from my partner's phone to my phone over WhatsApp then took the SD card out of my partner's phone and tried to delete it from her internal storage. It said the file couldn't be deleted because it was stored on the SD card.... yet, taking up space on the phone. So it was like having a dead body, no life, but taking up the room, on the internal storage, but when the SD card was put back, all "bodies" danced back to life again, making the video work as it once did. So it thinks they're saved on the SD card, and are, yet can't be removed from the phone and still taking space. In effect, it copied them but won't let the files leave the phone. So it was a weird mutation copy merge from internal to external storage. Sigh
So, I think I have to buy a new charger (current one charges but doesn't connect the phone to the pc) and manually cut from phone files and paste into sd card files, unless anyone has a better plan or actual way to fix this?
Thanks for your time,
Cormac
update
Well this is most interesting............................
I went to the shop and bought a cable that worked. When I connected it to the computer, I was able to see ONLY SD card, no internal memory..... so now it looks like it has dissapeared.. and merged with the internal memory.... which means that it now doesn't allow us to put stuff into the SD card. However, It seems to think it has more space.. I am hopeful it can allow this. I had to delete an app to make room for Facebook messenger update. Despite having the SD card in the phone... I don't like this... I dunno what to do. Any help welcomed.
Thanks,
Cormac
If you want seperate storage you have to use your SD card as an external storage rather than using as an internal storage. & Why did you buy a cable? The charging cable can be used for transferring data.
