SD Card gone

Woke up this morning and my stock unmodified DHD told me Backup Everything has failed (normally scheduled @ 4am every day). Logs revealed it could not write to the SD card mount point. In addition to this notification bar was displaying "SD card removed unexpectedly".
Initially I thought this would be related to the recent OTA update and SD card issues being reported by various forum members with relation to it.
However upon further reboots and detailed examinations the phone could not find the card at all. This prevented me from being able to format the card even after a reboot. Same results with multiple card readers on different PCs and even in other phone handsets... Nothing detects the card anymore.
Looks like the HTC bundled 8GB microSD card (class 2) is broken for good... Lost all my NYE photos and videos... Restored from an older MyPhoneExplorer full SD card copy onto a spare SD card and seems to be working ok now.
What I'd like to know is whether anyone else has experienced similar hardware failure on their bundled SD card.
I didn't expect such a card to fail within 3 weeks of purchase. And shipping the phone back for SD card replacement would not be worth the postage fees for me. Overall I'm finding Android platform very unreliable.

I had frequent dismount on my class2 microSD 8 gb card by HTC (made by Samsung). It got so irritating that I need to reboot my phone to gain access back.
I changed over to a Sandisk 8gb class 4 microsd card, and the problem is solved.
Think the microsd card is crap, and has nothing to do with the android OS.

I (and many other users, it seems) have the same problem with the SD card being fried. The fact we are all getting the problem now indicates that it defintitely the result of a recent update, and not because the "card is crap"....

well as stated in another thread I had this problem from the very first day I got my DHD, after changing to anothe uSDHC the problem is gone

See existing thread...
http://forum.xda-developers.com/showthread.php?t=897312
It appears that replacing the SD card with a new one is the way forward, try to get one off HTC if possible. I havent heard of any replacement cards being fried yet.

Wow, a Samsung SD Card that dies, unheard of... (former Galaxy S i9000M owner....)

I'm so far doing alright with a spare SanDisk microSD. Which card did HTC issue as replacement?

SD Card is Damaged. Try Reformatting it.

Anyone else getting this with their S4? I bought my S4 two weeks ago and a Sandisk 64gb card to go with it and started seeing this error about twice a day. I returned it for a Samsung SD and didn't see the error for almost a week until today.
The card actually appears to be fine, all I have to do is remount it after seeing the message and all is good, it's just worrisome cause I store all my photos on there. I'm wondering if it could be the phone itself? I have one day left to exchange it, but it's rooted.

SD Errors are because the card is physically moving when its being written to. This cause bad sectors on the card. Try putting a piece of thin scotch tape and cut to shape of the face of the SD Card. See if it fits more snug....
Are you jogging with the S4 or something? Samsung SD's are class 10 which I think write faster. Maybe that is less likely to cause damage because its written so fast? Not sure....
Try the tape trick and see if it reduces the problem. Else its a physical problem with the slot.

i also have a class 10 64gb, some guy on the forum posted this problem too, he said that by formating the card with a PC and then formating it with the format utility in the phone settings has solved his problem. If not, might be a slot problem like slider mentionned

I had this problem too with my 32 gig class 10. When I put my shock absorbant case on it my problem went away

I had never had an issue with a Sandisk card until my S3 ate a 32GB. I then started readibg how the S3 ate non- Samsung cards. I have been using a Samsung card with no issues

hope you make regular sdcard backups and copy to pc
polish_pat is correct, reformat your card with sdformatter, use Full Erase On and Size Adjustment On
Of course backup first
you shouldn't have to reformat again in phone--
if the card is good this should solve your issue

I had tried 3 different San disk 64GBP class 10 cards and had this problem, the fourth one works so far...doing some searching I found lots of complaints from lots of different device forums about this card. Only fix I found was running chkdsk repair on the card in Windows but this only worked for a few people ( couldn't save my first three cards)
anyway, imo exchange the card or better yet buy a different brand

Posting here as doing a search revealed this is the closest to the problem that I'm having. I've had my AT&T Samsung Galaxy S4 for approximately 1 month now. I purchased a Sandisk 32GB SD Card for the phone. Two days ago I began experiencing issues where when unlocking the phone I would notice the card would unmount then remount (this was in the notification bar). Later that night, the card unmounted and there wasn't any way to get it recognized again. I posted in some other forums and someone said there were some good posts here.
I've contacted Sandisk regarding the card and they refused any involvement stating it's a problem with the phone, not the card. They determined this because once I was able to get the phone to recognize the card and plugged the phone into the PC, the card was able to be read. As long as it's readable, it's fine. After dealing with this I eventually found my MicroSD to SD reader and plugged it into my media reader in my printer. I had quite a few issues from time to time reading the card, however I can't 100% for sure say whether this is the card or the printer.
Anywho, I grabbed copies of what I needed. Formatted the card on the PC, then formatted it on the phone. I began to copy my entries however at one point instead of saying I had 29.* GB Available, it said something like 2.0 EV of 3.0 PE or something like that... these weren't the typical numbers I've seen nor the units of storage space. I apologize that I can't recall that information. I reformatted again and it worked. Left the card in the phone empty over night then tried to copy files later today. This worked.
Now, approximately 48 hours after the problems began, I noticed more issues. SD card stated that it had been damaged and that I should reformat it. While this message stayed in notifications, I confirmed I was still able to read files on the SD card. When googling that error hoping I'd find more resources, the card again unmounted.
One of the resources I found had me do a CHKDSK /F /X on the card. I did this and found no issues. I've replaced it back into the phone and it seems to be working for the moment.
1) Are there any confirmations if this is a bad card, or if perhaps any applications are causing the card to do this? I do have QuickPic and have enabled some of the hidden file features if that helps.
2) Do we know if there are any logs that can be pulled to help verify this?
3) Is it a specific card? (I've heard SanDisk 32gb, but also have heard non-Samsung SD will fail)
Looking to get this resolved ASAP. This card was purchased directly from AT&T when the phone was purchased. I am just looking for some confirmation that if I have to buy another card, I'm not going to gamble if that's going to have the problem as well.
Thanks! If I forgot anything please ask!
Edit: Per the thread, this is a Class 4 card. Also the phone was not moving when it was writing data. I've been couch-ridden all day and unlocked it. I don't believe the phone was in deep-sleep mode as I had received a text not long before I began noticing these messages.

same problem
i have the same problem and guess what ?
the phone is acting like the ***** it stays ok for 3 weeks while that time i download to many stuff to my ext card 32g Elixir Memory after that it crach and give me notification that sd card is damaged and i have to reformat it sucks
by the ****in way this's the fifth time it crash i changed the memory to sony and same and changed to Kodak and the same
so abso****inlotley its the S3 for me soon its going to trash

I9505 - SD Card unmounts and mounts again when using it

Hi all,
I have an I9505 and I'm having some problems with my microSD card;
When I'm using the SD Card with a file browser, after approx. 20 seconds it unmounts and mounts itself after a couple of seconds.
Tried multiple file browsers. All are having the same issue.
When listening to mp3's located on the card, the same thing happens.
The microSD is a SanDisk 32GB class 4 card.
Then I replaced the card with one that I've had laying around.
A 4GB Samsung micro SD. Also class 4. Same thing happens here.
I've originally used FAT32 but formatted it to exFAT just to try. Again, same thing happens.
The SD card is not the problem because I've used it for a year on my S3 I9300. Never had problems.
The phone is not yet rooted. (don't think it's relevant though)
Not sure if it is a software issue or hardware issue.
Anyone having similar problems?
I'm thinking of returning it for repar but peraps a sfuture firmware update might solve it?
Do you guys have any suggestions?

Sounds like a dodgy card i had that issue. No firmware update will solve it because i got a different card and its worked fine.

live-evil,
I actually tried another card. I had the same problem.
It was a class 4 as well.
Perhaps a class 10 would be better.
This card worked for over a year on my SGS3.

Clearly i can't read, sorry its written in the first post i am just dumb i guess. Anyway i doubt class 10 or class 4 would have any effect. Could be just a problem with the phone's card reader.

You're probably right.
I will return it for repair and see what they say about it.
Btw, when connecting the phone to the computer and when I try to transfer files it works for about 20 sec and the card is unmounted.
So basically, whenever you try to rea/write to the card it unmounts.
But when puting the microSD into my computer directly (with an microSD to SD adapter) it works just fine.

I and other people in the forum are having the same issue with SD cards previously working fine on SGS3 (my card is a SanDisk, 64 GB, class 10).
I guess is a SGS4 issue, I hope a software issue to be solved soon! :fingers-crossed:

I've searched the forum for other similar topics but didn't really find something.
I guess I have to improve my research skills
I'll wait for the next update to see whether it'll solve the problem.
btw, I checked yesterday with my brother who also has the SGS4.
We bought them together, the very same day.
He doesn't have any problems with it. It works just fine.
But he didn't install the latest update via Kies...

Guys,
A small update regarding this issue.
I've read a lot of bad reviews about SanDisk microSD cards so I decided to buy a new one.
I've bought a Transcend Class 10 32GB microSD.
I didn't have any problems with this one ever since.
I'm using it for two days now without any problems.

I was using sandisk 32 gb class10 on a i9300 with no problems, but in my i9505 is mounting and unmounting alone... same sd card.... :silly:

This is a bit old sometimes it works, sometimes it doesn't, plug the card in a digital camera (any camera is ok) and format it. There is no logical explanation why it works but this helps bring back to life dodgy cards or you can try a low level format, there were a few freeware tools floating around, just give it a try before buying a new card

Reseating the card?
Last week my wife started using a 64GB Sandisk Ultra memory card in her S4. The next day she complained about battery and part of the phone heating up.
I stopped by this thread to read all your advice, and figured I'd file a support ticket with Sandisk. While doing that I removed the card to write down its serial number. I re-inserted the card and from that point onwards, battery life is back to normal and that area of the phone no longer heats up.
Is it plausible that some of these problems stem from improper insertion..? (Alternatively: the card holder is a bit iffy) I notice one suggestion here was to reformat the card in a camera. Well, I suspect that the mere act of removing the card and re-inserting it plays a role here. (if the way the card was formatted would factor into this, it would be easy to reproduce -- besides, FAT32 isn't that complicated to get right from a developer's POV, and I suspect the same holds true for exFAT)

SD Card notification update

So I searched the forums and noticed a ton of other people had this SD card problem coming up. The SD card frequently says that it has unexpectedly ejected and then the SD card notification appears. Sometimes the pictures on my SD card doesn't even show up until it registers the sd card is installed. This has been something of major frustration. My family member got the gold version of the phone with me and they don't have this problem at all with the same exact SD card. They never encountered this problem. Only when it is installed for the first time or the phone is rebooted. I exchanged the phone once already and the new phone had the same problem and I am worried it is going to be a crap shoot.
I DID notice however that when I used my 16 GB Kingston SD (low write speed) card I never had this problem at all. It was functioning just as it should be. Both 64 gb sandisk and samsung SD cards (90mb/s write speed) had this problem but my 16 GB kingston did not. I am wondering if it is either the size of the card, the brand of the card or the writing speed of the card that is affecting this issue. I was wondering what other cards people were using. Either way my family members phone reads all cards perfectly so it still seems like a phone issue but at the same time different cards are working on the faulty phone so I am wondering if people have any theories.
Also I was wondering what people ultimately did with this problem. Did people keep replacing it until they got a working one? Did you just ignore it and it went away eventually? Did you just not use the SD card? Or dud you just deal with it and just swipe it away whenever you see it?

Scotch tape. Bingo

Good Lock app from the Galaxy App store fixed the issue for me. A welcome side effect...

I've had 3 s7e and only my first one exhibited the SD card issue, I have a Samsung pro+128gb, all three were sd820, I suspect the initial batch of s7e suffers from it but just a thought

SO SD Card Issues

So I got this phone a few days ago. I use jet audio plus for my music and have about 30gb of music on my SD card. Pulled the card outta the old phone and put it in here. It reads it fine and saves all my photos. I noticed that the music app will sometimes go blank for a minute and my playlists will empty. After a few seconds, the music all comes back like it is rereading the SD card. First thought was maybe a problem with the app so I emailed the dev and they told me to troubleshoot and see if it happens with music not on the SD and then try music on the SD on Google play music.
Problem did not occur with music on internal memory. Problem did happen in Google play music. So then I checked my photo and noticed the galleries do the same thing and go blank for a second and then reload.
The memory card is maybe 2 months old and it's a higher quality one with a good speed rating. Before I was gonna reformat it, I figured I'd check online and see if anyone else reported an issue. Sure enough, I see samsung.com has a topic in their forum and tons of people are complaining about the same issue with many different sizes and types of cards. I was surprised that this wasn't posted here yet (at least from my quick searches).
Anyone else experience anything similar? Any feedback? News?
Auto correct changed S8 to So in the title*

Still no update on this issue. Thread on Samsung forum is 8 pages long of people troubleshooting, so far no solid fix. I'm not (knock on wood) experiencing the random reboot issues that others are. Perhaps those who are should download SD card monitor and see if their card is going crazy too.
https://us.community.samsung.com/t5...cpage/board-id/GalaxyS/thread-id/22859/page/8

All I can say that when my card started disconnecting like this on my previous Samsung phones, it went bad withing few weeks, I mean bad like not able to access it at all. If I may suggest, do full back of everything on that card, also check LOST.DIR, if anything is there you already have some files corrupted/lost. I don't know if this is SD card issue or phone error corrupting the card, but I lost about 4 cards this way over the years, but nothing recently and my S8 works fine.

Try backing up the card and reformatting in the new phone. I had a similar experience going from the s6 to the s7. No issues with s7 to s8, so far, though.

I've had very bad experiences with memory cards and cell phones. To be fair though, those were crappy memory cards I'd bought and I certainly got what I paid for. Now with this new 256gb Samsung EVO card, I'm hoping good things for it. Reviews certainly paint it in a good light.

I'm running the Xtreme level SanDisk. I am worried about the card being burnt up, but I don't know if it's the problem. Tried other cards like other people have in the topic I posted, same results.

I just want to say that I have personally have had VERY bad luck with SD cards I get off of Amazon. The ones I buy at a store never suffer such issues.
This is just my own personal experience, others may differ.

Issue still on going. More and more people reporting this on the Samsung forum.

Have people tried formatting using the phone? I haven't had a problem yet.

I formatted a Samsung 64gb ultra as card that I got from target with my phone. It disconnects. It has nothing to do with Amazon, or cheap sd cards.

One thing I thought of, make absolute sure the card is seated flush in the holder. Sometimes a corner will fight its way out. I put it on my desk and lightly pressed until it clicked. Obviously you may have too but I'm just trying to think of things before blaming the card reader in the phone.

Yes, people have tried all kinds of trouble shooting. A lot of people formatted in the phone and on the pc

Yeah right after I made my last comment I went and checked that. It didn't go back in until it was as flat as possible. It seems to be working so far. I also polished the pins with brass polish to ensure a proper connection. I'll come back later to update if everything stays okay or not.

Having the same sd card problems with my Sprint S8+. Sometimes it reads it and sometimes it doesn't(ghost icons) with constant different sd card notifications .
It's a new 256gb samsung evo pro card that came with the $99 immersive bundle from Sam but tried my 64gb pro card out of my Note 4 and same thing. Of course tried formatting,reseating card and sam support said it had to be encrypted which was no help.They did give me a ticket and label to send it to them for repair.'
Now the question I have.......are there people that are having NO sd card problems with putting apps and folders and such on it ????Wanting to know if it's a possible bug/software problem that will have a fix or a hardware problem with my phone and think that I should send it in. Never had any problems like this with my Note 4!

My sd card seems to be fine after reinserting it.

I have not come across any issues with my SD card (Samsung Evo 256GB) on US S8. No error messages what so ever. Actually kind of surprised, since in the past almost every Android version update brought some new permissions and messed up some form of SD card access. The messages about removing SD card is not normal and it will corrupt SD card if it happens during write cycle.

No apps. Hundreds of folders, thousands of files. SanDisk 200 gb.
I am getting some strange issues related with write permissions on micro sd with some apps. I think are related with encryption. I am testing.

No encryption, I don't believe in full encryption, most of the stuff is pictures and videos which don't need to be encrypted, for things that need to be secured I use secure folder or encrypt the file itself. Also I don't care what anybody says, encryption increases usage of CPU, slows it down and uses battery. It also increases the risk of corruption and file error and in case of some errors there is no way to access it from computer to recover data.

Update: disabled micro sd encryption today and write access permission issues seem to be solved so far.

Sd card disconnected again. So obviously the slot is loose garbage. I put the phone in my pocket while listening to music and the music stopped. I pulled the phone out and the sd card was unmounted. The sd was a huge reason I went with this phone and It's ****!
