using old microSD card

i know this is probably a simple problem with an even simpler solution, but why is the EVO not recognizing my card? it's got some of my contacts, but none of my other data is there. does the Droid (the phone i came from) use a different directory or something?

Contacts aren't usually stored on the SD card unless you're using an unusual app. I (and I believe the majority of Android users) store our contacts in the cloud (Gmail, facebook, etc).
Could you be a little more specific on what data you're missing?

i'm missing literally everything on my SD card. music, apps, data, etc.

Can you read the card in a card reader? If so, you could copy the data to your PC, format the card, install it in the phone and then move the data over via USB.

seemed like a good idea, but didn't work.
is everyone sticking with the included 8 gig, or is no one else having problems switching?

No trouble here with my 16GB card. Maybe it doesn't like how your card is formatted? Try copying everything to your PC, reformatting the card, then copying everything back.
**hah.. just saw the post above suggesting the same thing. I didn't see any mention of what format you used, though.. mine is FAT32.

I'm using my 16GB card from my hero...no problems reading it here. I assume you've also tried reseating it (And double checking you are seating it right by making sure you can read the included 8GB after seating it again too)?

I used the 16 gig I had in my Moment and the Evo evowned it. Maybe the card went to pisser early and right on time but now it is broken.
Had to order a new one.
I would say format first.

i did format it; no fix still.
this sucks, man!

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.

Thanks!
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.

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?

SD card not read by apps in some cases..

Hey guys -
An issue I've been having since I jumped up to CM13, was wondering if anyone could point me at things to check.
Searching, doesn't look like others have had this issue, so..
I'll also note that it's *possible* this issue existed in Viper (before CM13 was finally useable), but that was a while back, and I can't remember clearly.
In either case, some apps can't seem to read the SD card.
Examples - The built-in Gallery. No matter where I have the camera app save pics (Internal or SD), the Gallery won't report any images being found.
Another example is my live wallpaper, which pans and changes backgrounds. In it's settings, I can easily select the directory on the SD card that has the images, but when it starts, it can't display any of the files, reporting that the directory could not be read.
The card is 32Gb, and the issue continued after backing everything up, and re-formating card in phone. (And then copying everything back over.)
So was wondering what else I should take a look at. (Permissions, etc?)
Cheers -
Mike

Faulty sd card for what so ever reason...
Sent from quite brutal hTc 10 ..

Tried a different card this morning - formatted it in-phone, and copied over docs from old SD card (using PC as intermediary), same thing. Wondering if it's some permission thing or something on a folder/mount point.
Apparently I'm the only one having the issue, though, so maybe it's something I've done to my phone. Grr.
