External sdcard woes

Before owning the Note 2, I had the S3. The problem with the scared happens on both phones.
When I first got the Note, I removed the sdcard from the S3 and put it straight into the Note.
No media showed up. Formatted in phone, transferred media, all working as it should.
Today, add a video to card, doesn't show. Add a photo, doesn't show.
Format card, transfer media. Nothing shows up.
Am reluctant to buy another card as I tried three Cards in the S3, and the problem was present with all of them.
PS using root explorer I can find all the media, and play them in their respective apps.

Thanks, for some reason that works for my videos, but not with photos and music!!!!
And that is more of a workaround than a solution. Ideally I would like for it to work as it should. Impossible for me to go back to stock as I will always need root to vieww my media(ok, I will probably always be rooted, but I want the option)
Edit: tried again and my music and photos are now showing (using Directory Bind)

Ive had issues like this on my EVO. Try installing a "media scan" app from the market. It rescans all media content on the phone and then if you want you can remove the app after its done. I had 2 years worth of photos on my 16GB SD class 10 and no pictures or video thumbnails / pictures at all would show. Ran the app and fixed all the issues.

I did try a couple of those apps yesterday.I dont know if either one worked.I mean I know nothing showed up, but it was as though they never actually run.

Same issue
:crying:
I tried formatting several times and copied the data back, nothing helped. Also copying files from my comp to the sd card and internal storage in the phone is very slow. I bought the device yesterday, its stock unrooted.

I don't believe media (pictures/video) show up until mediascanner detects them and sticks in some internal database.
So just copying files onto your external card and popping it in isn't going to work.
media scanner is normally triggered during a reboot, and some apps can trigger it. (generally via 'rescan media' buttons).
Also make sure you don't have a .nomedia file there, as that causes media scanner to skip the directory.
( media scanner can really grind on directories with tons of files )

I tried a different memory card from my old Sensation and it read the files perfectly... can any of you help me with the copying speed.. it took me 35 mins to copy 1.20GB... just to be sure i i tried to copy the same date using the same data cable and the same usb port, onto my wildfire, and it copied it pretty fast. Any idea ?

It sounds like the Sensation card just has slower transfer rates. While your wildfire has faster transfer rates but you are experience issues on the phone side.
Just to confirm, you have formatted both cards the same way and one works and the other doesn't? If possible try to format the card from the phone. Have you tried a sandisk card?

Both the cards are Sandisk 8gb cards, both formatted on the Note 2. I transferred data to card A when its in the wildfire, i formatted the card and put it in the note and formatted it again, and tried to copy the same data to card A, it takes more than 3times the amount of time... data transfer has been slow to the card while its in the note

I have read somewhere that there is a " .nomedia " folder somewhere. Delete that and see what happens.

Also on top of that, when you formatted the SDCard did you format in the PC or in your phone through recovery? You will want to format through recovery.
I would recommend upgrading to an ext partition and then formatting again (if you don't need the ext). I have found that even formatting the SDCard on some roms (because the way they work) it doesn't wipe everything and upgrading the to ext actually changes the file system of the SDCard rather than a quick format. Then only copy your media back to the card. Dont copy everything like .android, data, and stuff like that. Just what you want to keep.

Is there any chance you have a counterfeit Sandisk card? Did you buy it from an authorized dealer? If buying from Amazon make sure you only purchase directly from amazon, LLC and not a third party vendor.
For reference which sandisk card do you have what class is it rated at?
Daniel

No the card is legit, i got it in the box when i bought the HTC Sensation and worked fine on the sensation. It has good copying speed if i put it in another device like my wildfire even now. I checked copying speeds yesterday using the same card in my wildfire and my new note, but it takes forever to copy data to the card while its in the Note. I have not rooted my Note yet. Its factory stock as of now.

Tried that, and it worked. thanks.... But still having data transfer speed issues... i copied data to the internal memory and even that is slow... this problem is not limited to only my sd card, but also the internal memory

If your internal memory is slow I would consider that cause for concern. Perhaps try running benchmarks and comparing your results to those in the benchmark thread. It may be worth returning it for another phone if you can't find a solution soon.

you might have to reinstall your rom

Isn't the speed difference just to do with the way the Note 2 connects to the pc? I.E MTP as opposed to mass storage? I seem to recall my G.F's original Note is dog slow at data transfer in MTP but much faster in USB mode....shame the Note 2 can't do this, it's one of my reservations about buying it.

Now it makes sense to me, thanks :good:
Is there any way to connect in USB mode rather than MTP??

Can I ask if anyone else suffers from the same problem as raised in the OP?
I would imagine its not "the norm" and yet I have had the same issue on both the S3 and Note 2.
Whilst, it is now working, I am having to use Directory Bind, for it to do so.
I put in a new 64GB card on Saturday, recognised straight away in Settings/Storage, formatted fine in the phone giving me 59+GB of free space.
Put media on it...nothing shows.
I cant ever see my phone not being rooted so it can be worked around,but it just seems strange that I have had this on both phones and yet nobody else seems to suffer from it.

For whatever reason I don't think Samsung enabled USB mass storage mode on either the S3 or the Note 2. It's the one thing that's holding me back from buying one at the moment because I use iTunes Agent to sync with iTunes, and that requires the device to be in mass storage mode when connected to the pc (or you can take the sd card out and put it in a reader, but I don't like to take the back off too many times as most phones end up getting really creaky). It's a real shame because I'm just itching to get one.
Have a look in the GS3 forum - I think there's a thread where someone has created an app that enables you to toggle USB mass storage mode, but I think you might have to be rooted and have a custom kernel. Don't quote me, that's from memory

There are a couple of threads about this I think now. I browsed some last night. Sorry, I'm only on my phone at the moment so it's a bit awkward to try and find a link for you (what with having a Sensation with only a 4.3" screen They'll be on the first page or two I think.
My girlfriend's original Note had a similar problem with photos and media after connecting an external hard drive. Going into settings/apps and clearing data on the media storage app followed by a reboot sorted the problem for her.

Micro SD Card mount problem

Hey folks, I have a bit of a problem here. I just recently started having this problem of my micro sd card not being able to be mounted to my GS3 for anything. I don't know what the problem is nor how it can be rectified? So it's known, I'm rooted with the latest CW recovery mod for JB fw version 4.2.1. I tried recovering to factory settings but that doesn't work because I have wiped all my caches. Any ideas as to what I can do to fix this issue? I have no problem losing full, permanent root access by the way but also keep in mind that I currently do not have a computer of any kind. I was able to gain permanent root access when I borrowed my buddy's laptop last week but gave his laptop back.
The message I always see on my phone when I go to manually mount my SD Card in Settings is ..."Your SD Card is ready to be removed."

Honestly, this sounds like your SD Card is in its last days, so to speak. This happens quite frequently and they just do not last forever.
What brand is it?
What is its class and size?
How old is it?
Where did you buy it?
If you boot into CWM, can you mount it there?
Your best bet is to try your best to get any important info off of it, then format it. If you have the space, copy everything important to your Internal SD, then format it through the settings menu. If that doesnt help, you will need to try again from a computer. Use the SD formatter tool from http://www.sdcard.org
I am assuming the card was working fine on your phone and this just started happening recently.

The SD Card is a legit 64GB, Class 10, micro SD Card that I bought not even a year ago from Amazon for $55. It's the card that looks half red and hald grey. I had a ton of stuff on it too... movies, about 2k songs, tv show series, hundreds of pics, paid-for apps, emulated games and more. I think once I flashed a new different rom from the original regular CW 4.2.1, that's when my card was wiped clean. Now I can sometimes go to my sc card in the EZ Explorer Android app and it shows that my card has no files on it whatsoever.
Oh, I also get an error message of something like "cannot mount sd card... error." .... when I mount my card in the CW Recovery screen. I've also tried adding new files to the sd card and when I go back later that day or the next day, those files were wiped clean like they were never written to the card.
So now, the only place I can save files to is my internal phone memory.
So sad and blue...

Yup, sounds like its on its way out. Unless you specifically tell cwm to do so, it doesn't touch your external sd. Some people have made the mistake and wiped out their data by not paying attention to what they're doing.
Anyway, there are data recovery tools you can try to use. Many people have had some success recovering info off of flash memory like that.
Sounds like it was a sandisk, but it should be clearly labelled as such. If its not its probably a knock off. Youd be surprised how many fakes are out there. Even highly reputable sellers have been known to sell cheap knock off sdcards. They don't do it on purpose of course, but I've even seen where they came from stores like Best Buy. The last time I looked I think Samsung, Kingston and Sandisk were the most popular targets for fake sdcard dealers.
This is why I only buy Samsung brand cards, and only from sellers who are Samsung Authorized Dealers. They buy direct from Samsung so you can be confident that you are getting a real one.
Even so, the best ones are still known to fail. I'd google for flash memory data recovery to see if you can rescue some stuff. And I would replace the card.
Its always a good idea to keep a backup even of your sd data. Sorry for your troubles.

When you get a new card, there are ways to tell if its a fake or not. You will have to search them out as I really don't remember, but just so you know, the info is out there.

Camera images never saved, disappeared from gallery.

To make a long story short, I took some irreplaceable pictures today that disappeared.
I have my camera saving to my 64gb memory card. I took a few pictures and a couple of panoramas and they ended up showing up glitchy and useless.
They didn't appear in the gallery with the exception of a few images.
It looked odd.
I rebooted the phone and tried to go into the gallery and they just weren't there. The previews showed up momentarily and then they vanished.
Now when I try to take a photo to go to my external memory, it works fine. It didn't pre-reboot.
Is there a method of:
A: Recovering my lost 10-15 images.
B: Ensuring that this doesn't happen in the future.
For the record, my card seems to be working fine. Music on it loads up quickly as well as any other images that I loaded onto it. Files open and there is zero lag. I don't suspect that the card is corrupted or anything.
Thanks guys.

You could try something like Recuva: https://www.piriform.com/recuva
I successfully used that to restore files deleted from microSD cards a few years back.

I'm unfortunately on a Mac. Guess I'll boot into boot camp and install it and give it a go.
I hope the pictures actually existed as files though and not some cached object.

Update:
Overnight, the saving issue arose again. I'm forced to use internal storage when using my camera.

I've seen this problem before. So SD cards don't work well with Samsung devices. I bought a Samsung SD card and never seem this problem again. I recommend you do the same.

I wish I wasn't broke :/
I'm using a SanDisk 64gb. Guess I've gotta dig up some cash and get a Samsung.
I don't see how this is an issue though.
What is your card formatted in? My current is in exfat. I'm thinking the format may be an issue.

It may be a kitkat issue. Google "kitkat SD card write". Root users are using a fix that sets permissions so the sd card can be written to by all apps as expected.

Right before I came across your post, I found some info on the kitkat issue with sd cards. I'm guessing that's what's causing this problem. Odd because it's the default Samsung camera that's messing up.
Oh, how I miss root. I just hope we get root soon. I'm pretty close to selling this phone and hopping on Tmobile.

I had this problem happen with very VERY irreplaceable pictures, on my backpacking trip to china, one of the most irreplaceable pictures of my entire life was taken, appeared glitchy in gallery, phone reset and it was gone.
after taking out the SD card, and doing many deep scans to try and recover the deleted pictures, it seems the pictures arent there, which leads me to believe it somehow tried to save it in internal memory (which cant be mounted as a drive, so cannot be recovered).
if you can somehow flash an older version of android (like 2.xx) you can mount your phone as a drive, and then attempt to recover deleted data from your internal SD..
yeah all i can say is ,,|,, you samsung.

I too have the same problems as the OP. And I am on SAMSUNG micro SD card! Guess it is one of those first batch gremlins?
However, I think the problem has gone away after I switch on the image "preview" option. Give it a try.

I had the same issue with a 64gGB SanDisk micro SD card. The camera would seem as if it was taking pictures but nothing was actually saved; they just shows as corrupted files in the gallery. I lost countless irreplaceable images from our honeymoon because of this. Once I switched to a 32GB Samsung micro SD card I never had the issue again, also saving the pictures directly to the internal memory solved the problem. I use the SD card for music as well so it has to be something with the phone writing to the SD card. From what I've read it's a issue with the compatability with samsung and non samsung sd cards for some reason.

Never had this issue with any of my Samsung phones (S2, S4, and now the Note 4). I'm using a SanDisk Class 10 32GB. I'd recommend pulling the files off the SD and doing a format. Download the App SD Maid as well for routine maintenance on your SD. Good luck.

My 64GB SanDisk SD card was giving unexpected unmounted errors, so I picked up a Samsung 64GB SD card. The unexpected unmount errors went away, but now I have this problem. Pictures are not saving to the SD card correctly. Sometimes it says media not found. Others the preview/thumbnail looks fine but the full view is just grey.
I am going to try saving to internal memory and manually moving to the SD card as I run out of room.

Pictures randomly became corrupt

Hi guys,
So the other day i go into the Gallery app and notice the photos that have been taken by the camera appear to be corrupt.
It is strange because it appears that the most recent pictures are viewable but majority of the older ones are not. All other album folders that i have created are fine.
Has anyone else experienced this issue? If so were you able to restore those images through the phone?
I'm sure if I connect the MicroSD card to a pc and use data recovery tools i can still retrieve them. I just find it kind of odd that it only happened to one particular album.
Images are being saved to a Sandisk MicroSD card.
Please see photos of what im referring to.

i've had 2 Sandisk microSD cards fail on me before. I read somewhere that sandisk cards is more prone to failure in samsung phones. Pity because my sandisk CF cards for my camera all work flawlessly. I went with Samsung 64GB cards. Last time they were on sale at amazon for pretty cheap.

It did that with a video of mine but it became normal a bit later. Kinda strange.

i had a similar thing happen to me and I had to format the extsd and it fixed whatever the issue was.

I'm having the exact same issue!
I just moved my SD card over from my note 3. Was working fine on that phone. Pictured look corrupt at random now but may appear back later on.
I'm gonna try backing up all my stuff and formatting.

Ya i find that very unusual. From my experience with external storage, when it becomes corrupt, most times all content is not readable. I guess im just going to have to do data recovery on the corrupt files, format it and transfer them back on to.

Same issue here. Noticed this a few weeks ago (2 or 3) and just deleted the blank images. Hasn't come up since then but I'll keep monitoring it.

Had this happen without the sd card...

Strongly suggest you hard reset if it happens on the device.
I had that happen on an SD card once and then ultimately everything got corrupted. Copy everything off it, Format it and copy back on.

Tablet destroying SD cards?

In August, I bought a 128GB PNY microSD card. It lasted almost two months, and then the tablet started acting funny. It would randomly unmount the card, it couldn't find my music files, and apps I had moved to the card would just disappear. I assumed the card was broken, so I eventually replaced it with a 128GB Samsung card. It's worked fine until the other day, when it started exhibiting the exact same behavior. I haven't been able to fix it.
I've tried formatting them both, but nothing seems to work. Windows can see the cards and the contents, but it's not able to format either card - it reads them both as write-protected, even though they're not. The only thing I can think that might cause it besides my tablet is Link2SD. I use this to move the large app data to the card since I only have 16GB of regular space. Could this be causing it? I'm at a loss, and I can't keep buying new cards. Any help would be greatly appreciated!

I regularly read this forum and this is the first time I've heard of an issue as described. I bought a a cheaper 64Gb mSD card and used it with my Tab S day one. I've never had an issue. Could be you just have been unlucky? Were your cards from recognized brands? I suspect that the larger GB cards have lower yields so you need to buy a better quality card.

I definitely won't rule out being unlucky, it's definitely in my blood. I just find it odd the exact same thing would happen to two cards, months apart and with different brands and purchasing locations. PNY isn't super awesome, but they're not garbage, and Samsung is fairly prominent.

Samsung phones and tablets are occasionally said to be sd card killers. The GS3 definitely was, killed like 3 cards with the same result as you got.
Sometimes I feel it also affects certain sizes of card. The GS3 ate 16gb cards, but not 32gb cards. So it's quite possible that a different size card may have a longer life.
Not saying this has any base in research, just my experience.

I've read this on other forums as well, specifically the GS3 part. I wish there was a way to be sure. What happened to destroy the cards?

I am using a Samsung 64GB and Link2SD. Haven't encountered any issue so far. But on a related topic, I managed to destroy a 1 year old Sandisk USB drive yesterday while trying to format it as NTFS. Now Windows won't recognise it al all. It could just be that the flash memory had defects to begin with.

Does Windows make the bell sound when you insert your microsd, if it does you should be able to recover it, if it does not and you have checked the reader is working the microsd might be dead, if you have an sdhc adapter see if a camera or any other device will recognize the card, if it does format it in that device then see if windows will see it, I had an 16GB microsd a few years ago completely die when i froze while i was copying music to my phone, nothing would recognize the card after that it was totally dead, and i got a refund.

Does Windows make the bell sound when you insert your microsd, if it does you should be able to recover it, if it does not and you have checked the reader is working the microsd might be dead, if you have an sdhc adapter see if a camera or any other device will recognize the card, if it does format it in that device then see if windows will see it, I had an 16GB microsd a few years ago completely die when i froze while i was copying music to my phone, nothing would recognize the card after that it was totally dead, and i got a refund.

Windows does recognize the card, and I can see the contents of it and copy all content OFF the card. However, trying to format it just tells me the disk is write protected. I've done everything in my power to try to unlock the disk, including third-party programs and commands in the DOS prompt, but it's still write-protected. So bizarre!

I had the write protect problem on an card myself a few years ago, I downloaded an app that let me remove the protection and the card worked fine after that.
Does the write protection stop a camera from formatting the card, or only windows, as i said it`s been years since i had my problem.
Have you tried a partition manger app, I have used the one below for years, but i dont know if it will be blocked by the write protection as well.

I actually don't own a camera, the only things I have that take SD cards are computers and Android tablets/phones. I haven't tried that particular partition manager (Chrome won't let me download it - it says it's unsafe?), but the Windows manager and an HP one someone recommended both say "Failed to format disk."

I have uploaded the app i used, It years old so i most likely does not work but you can give it a try.

I would download partition wizard with another browser or force chrome to download it. Its a perfectly legitimate app which I've used many a time.
You need a low level format and partitioning software like that. Windows is useless on its own.
Delete the sd card partition, recreate and reformat.

I downloaded it through Edge, and everything worked fine. It even seemed like it was going to work, until I hit "apply". Then it sat and thought for a while, and told me there was an error with the format of the disk. Instead of trying to recreate 2 partitions, I tried to just see if it would format at all, and when I applied that change, it said it completed successfully, but the disk was still in it's former state - full of my files, fully readable, and definitely not formatted. I feel like this stupid thing is haunted.

So for this problem, can anyone give me an opinion on whether it's hardware or software based? Such as, do you believe this is happening because it's a Samsung tablet, or with a bug on their current Android version? I'm hesitant to keep putting cards in it, but I want to use my tablet!

Have you flashed or rooted your tablet? , are you on kitkat or lollipop?

It was rooted, but it was on stock 5.0.2. I used root to run Link2SD.

Link2SD only moves apps not music, so why did your music disappear, have you used any cleaning apps as they can delete files that you want to keep.

Well I had Link2SD moving all kinds of crap. It was linking games, books, comics, magazines...lots of stuff. My music didn't disappear - in fact, nothing did. It's all still there, only the tablet can't see it. My computer can see it, I can copy and open the files, but I can't write anything new to the card, and I can't format it.

It sounds like your tablet is loosing the location of the files on your microsd, I would say Link2SD is at fault, I would give the developer a email with the problem your are having and see what they say.
EDIT: I just read the reviews of LINK2SD and some people are reporting files are disappearing.

@greycobalt: I recently had Link2SD card stop mounting the 2nd partition (formatted as ext2, that is used for Link2SD).
I'm using a SanDisk 64 GB micro SD.
1) Did you have this same problem? Were you able to recover your app files when you put the SD card into your computer?
2) Oddly enough, I can see the files on the 1st partition of the card, which is formatted to FAT32 and I can see everything on that in file explorer. You said that these even disappear?
3) What file format did you have for your microSD for Link2SD to be able to link apps to it?
