micro sd forcing reboot - Samsung Epic 4G Touch

allright. i of course have the epic touch.
its stock. running
android 2.3.4
kernal 2.6.35.7-sph-d710.eg30-cl435734.
updated prl, profile, no firmware updates and current android.
i put some music on my pny 2gb micro sd (sd-c02g is visible on the card) and placed it into my phone. at that point, my phone began to randomly (so far as i could decern, now that i think about it, it could have been rebooting after each media scan. not sure.) took me a min to calm down and start going through troubleshooting steps, which of course first began with making sure i was updated. made sure the battery was in place. nothing i could tell. then, i decided to undo the last change i made, by taking out the micro sd. and presto! it quit rebooting.
any clues as to what might be causing the problem? is it inherrant in the software? could i have my sd card formatted wrong? perhaps my phone doesnt have a good taste in music?
tl;dr micro sd card forcing reboot. solutions?

just reformat it on your pc should fix your problem.
if I helped give me a thanks

soon as i get to a micro sd card reader, i'll give it a shot and let you know!

Reformat fixed it. Thanks a million!

[Q] HTC Desire doesn't recognize sd card, please help.

Hi everybody,
I posted a similar post in one of the threads, but I did not get any replies. So I thought I might as well post a new thread.
I really hope that you can help me out.
My HTC Desire doesn't recognize the sd card (Samsung micro SDHC 4gb) that is in it. It also doesn't recognize another sd card (SanDisk micro SD 2gb).
I've tried to follow up the steps 'chippieuk' has listed in this thread.
Everything went fine, until I reached steps 8 and 12, because my pc doesn't recognize the sd card either. (I've tried to put it in two other computers and another phone, but it hasn't been recognized in any of them. I've also tried to use another sd card in the sd card readers and adapter, and that sd card was recognized, but it was a SanDisk micro SD 2gb.)
Here's some background information.
Something like 7 months ago I rooted my HTC Desire (in the process of rooting I partitioned the sd card) and I put custom ROM 'opendesire v1.5' on it. I was satisfied with it, so I never changed it since then. But my HTC Desire stopped working properly something like 6 weeks ago. Every time I switched it on, it went into bootloop. So two weeks ago I did a hard reset via 'hboot' and my phone seemed to work again, but then I discovered that the sd card wasn't being recognized and that has been the problem ever since.
I've, btw., (temporarily) unrooted my phone with a RUU (android 2.1). I've not yet upgraded it to android 2.2, because I want my phone to function well first and I will probably root it again soon (if I will succeed with my sd card etc.)...
So... Have any of you got an idea? Could it be something with the readers that I've used (that they can't read micro sdhc cards)? Or because I once partitioned it? I really don't know...
Once again, I would really appreciate it if you could help me.
Thanks.
Regards
If nothing is picking it up then you have no partition on the SD card, or the wrong one. Format it with Windows to FAT32. If Windows picks it up, then Android should pick it up. If it isn't picking it in Android after the format, go to Settings > Storage and see if it's mounted in there, if not, then mount it, if you can't mount it, then it's either a problem with the rom or a problem with the SD card.
Okay, thanks. I'll try that.
Is it, btw., possible to get the data that's on it back?
Not if you format it. To be honest, the only way you can get data off it anyway is by getting it to mount, which it isn't doing.
Yeah, true... I should have made a backup. ;p
Okay, I just connected my phone with its sd card to my computer.
It actually shows a 'Removable Disk' in 'Computer',
but I cannot access it when I try to format it.
So I'm going to try to format it now, using an adapter.
Let me know how it goes
Hmmm.. When I put the micro sd card in an adapter and insert that into my computer, it sort of reacts to it. The icons at the bottom right sort of move, but that's all. When I look into 'Computer', there are no removable disks. I really don't know how to access it..
Plug it into your PC. Go to start, right click on my computer and click on manage. Click on disk management on the left and see if the SD card loads up

Okay, so I tried what you said, but the SD card doesn't load up.. I also tried it with that other SD card I talked about, just to check again if it really isn't because of the adapter, but that SD card was recognized.
Put it in your phone and loads up Android. By default, if Android detects a non compatible SD card then it will ask you to format it. If you don't get this option then I guess it's buggered and you'll need to get a new one.
It appears to be a USB brick....

Damaged SD card?

Hey,
So ive been having some problems since i got my T989 in november. About once a month my SD card just seems to fail... like just now, i rebooted the phone (power off then on) and it comes up with "SD card is Damaged" Why is this happening? its getting really frustrating because i like to do all my nandriod backups onto the SD card...
Anyone got any advice? Could the card be faulty? The other times it was basically doing the same thing. Eject the sd card properly, remove it, plug it back in... Failed!... ugghhh.
Sounds like it is just that...sd card is faulty. They are so cheap that I'm not sure why you don't just buy a new one?

When I turn on my sgs2 this morning, I suddenly get this message:
damaged sd card
you may have to reformat it.
why is that? what caused it?
does anyone know?
because there is nothing wrong last night when I turn it off.
is it possible to fix it without reformatting it ?
I hate losing all those datas.
my sd card is transcend class 10 16gb, I have used it for only 3 months with no problem at all.
I have tried reboot several times, take it out, clean it and insert it again,
but nothing works.
Please help.
My rom: wanamlite v6.7
My kernel: Phenomenal Black v2.1
Try putting it into your computer and see if it opens. Also, windows may offer to fix it (which shouldn't reformat it).
Either way if you can get it to open on a laptop or something even for a bit you should be able to save your data.
Freezer trick (like for fried harddrives) might also work.

Why did u buy transcend sd card?i am using Kingston 16 gb class 4 card and i think it gives the best performance.Class 10 sd card should perform better than class 4.You may consider sandisk as second option.I am sure u are gonna lose ur data.
Hi Guys,
thanks for all the advices.
when first I connected the sd card to windows, windows could read the directory.
however, if I click on the file, it gave error message: file not found.
then, after did some searching on xda, I found more similar thread like this.
and some told me to run window error checking and chkdsk /r.
the problem is, it seems that every time I run these program, the sd card is getting harder to read.
then, I run them again and again, finally the sd card now can not be read at all.
Too bad, I guess it is time to reformat.
PS. I should do more reading and searching before I run chkdsk:

SD Unexpectedly Removed - NO Remount

Ive searched the forums here as well as google, and find many S3 users facing a Verrrrry similar problem, where their SD card is "Unexpectedly Removed" and then Remounts itself, and the process repeats, causing battery drainage, loss of access to apps etc.. Mostly Related to a SanDisk manufacturing default with certain chips.
My problem however, is slightly unique, in that, mine does not remount itself once it has been "removed". Once physically removed, and checked on a PC, all my files are still there, in working order. Ive Formatted, both "quick" and full format to Fat32, and the card works fine for about an hour to maybe a whole night if Ive done it right before bed. It seems as soon as it starts to be accessed in any way for more than ten minutes, it gets "removed".
Ive tried the following to try and remedy the problem. (Im fairly broke so buying a new card is last resort in my case)
-Both Formats of the card several times.
-Put it in another phone which reads it, format, unmount safely, mount into my phone, and no luck, doesnt even see it
-Factory Reset incase of any bugs in software that may be causing a malfunction of any kind
-Full Wipe X3 + Change of ROM
Im going to be borrowing a friends card for the night tonight, a spare 2GB he has, and see if the phone repeats the error, or if it really is fault of the SD card in question.

Kernel:3.4.53-cyanogenmod-g361781f
SD Card: Lexar 16GB Class 4 Micro SD HC
Anyone have any ideas as to what may be causing the problem? or does it really sound like the card is at fault? I question this only because the card works elsewhere, and works in my phone for the first little while, with or without files on it, after I format it..
I'll report back about the other card tonight.
Any Suggestions would be greatly appreciated, as I cant find this problem solved in any way, anywhere :s
Once you report back and if the new card works it sounds like the card. But if the second card fails it sounds like a hardware issue only if you tried different ROMS and kernels and going back to stock by using Odin.

[Q] SD Card Issues?

Hello everyone,
I just recently purchased a Samsung Galaxy Tab Pro 8.4. So far I really like it but I am having a problem. I have a 32 gig sd card plugged in and yesterday I tried putting some files on. Nothing fancy just music, a video, a couple kindle books, and some word documents. I had plugged the sd card into my computer dropped them on and put it back into my device. Well the device wouldn't find or acknowledge any of the files at all. It acted like they just didn't exist. So I plugged the sd card back into my computer and they were there. After a bit of rebooting my device I finally got it to acknowledge the stuff I put on. That lasted until I let the device go to sleep. This morning when I opened up my device everything was gone again. So I plugged it back into my computer and it was all actually deleted.
After that I tried putt stuff on it with the device tethered to my computer and the same thing happened. It wouldn't acknowledge anything kept on my sd card. Including kindle books.
I did some reading and just kept coming up with the kitkat and app compatibility issue that doesn't allow apps to save to sd but this doesn't seem like that. All of those posts seemed to be dated a few months ago so has that been fixed at all or is it still a problem and the only "fix" is rooting it? Is it related to the problem I seem to be having? If not what on earth is worng with it and how do I fix it?
I won't lie I am kind of a newb when it comes to anything beyond basic electronic issues so I really am at a loss for what is wrong with it.
Thank you in advance for any help.
Psylk87
P.s. Should I consider returning this tablet? The stuff I read about the kitkat seems like a huge problem when it has such a small amount of on board space. I have just basic stuff on it and still only have 6 gig on board left over. That means basically all storage will be on an sd card. I bought it to use for college so want to be able to take notes and reliably save stuff. Am I better off with a different tablet? If so what Android tablets would be best?

Any rooted tab is better.. Rooting it will allow you to fix your SD permission woes. More than likely the app you are using can't get access to the SD card thus why it shows up blank. Root the tab, and run the kitkat SD card fix app and never look back. This tab is great!

So basically it will always have the sd card issues thanks to kitkat? I tried opening the music and the video with the devices main video and music apps. But they also weren't showing at all when I went to look for them in the actual "My Files" section. Then when they totally deleted I got even more confused. It was 5 gigs of stuff just randomly deleted off the flash drive.
Is rooting hard? As mentioned I am a newb. I have never done anything like that and I have never used or worked with a rooted device. Won't it void the warranty and make it so I cant return it? It was fairly expensive so I am worried about ruining it haha.
I actually love the tablet so far so really disappointed with the issue. I have until the 14th of August to return it so I need to decide quickly.

Some people on this forum have reported that towelroot works on Tab Pro 8.4. It should be as easy as installing an apk and tapping a button. I already have CM11 installed so I didn't try it though..

Hi
I'm not new in flashing ROMs but I think somewhere I go wrong...
I had the Australian stock ROM and I thought to try a little bit de-bloated ROM to check if its better...
As I'm ALWAYS doing I did make a recovery full backup of my tablet and copied the TWRP Backup in my Ext. SDCard with the intention to move it in my PC for security. Reading how to flash the new ROMs, couple of times have been mentioned that I have to wipe EVERYTHING before I flash them... Against my better judgment I wiped my SDCard too and of course I wiped the new ROM too...
Oh well I thought I will restore my Backup and try again
1) TWRP did NOT read the backup from Ext. SDCard.
2) I d/l an Aussie ROM from SAMIFILES to start again and copy the TWRP Backup in SDCard in case something wrong etc...
Then All Hell Break loose
After Flashing the Full factory ROM I had in my tablet few only apps without ANY Google apps and I couldn't access my Ext SDCard...
When I took out the card to copy it in my PC and from there to tablet the card was corrupted loosing my original Backup...
After that I don't know how many times I've tried factory or XDA ROMs with all the time not able to access my Ext. SDCard (New one, works fine elsewhere) despite I tried ALL the SDFix apps in Playstore... I tried to change the properties of the card manually too but the same...
PLEASE can help me to Fix my Ext SDCard as the tablet is almost useless without it?...
have you tried copying the files to your main memory, then transfer those files from main memory to your memory card using the built in File Manager ?

There is a lot of misinformation and misunderstanding about the SD card permission changes brought by KitKat, and I do not believe the OP's issues are caused by those changes. We are unfortunately to the point where if someone has any trouble at all with an SD, they blame the KitKat permission changes; which is simply false in many cases. The KitKat SD changes have to do solely with write permission access and do not affect the ability to read the SD. The following article explains it well:
http://www.androidcentral.com/kitkat-sdcard-changes
And the KitKat changes certainly would not cause the card to be read after a reboot, then randomly not readable later, as the OP described. All this is pointing toward an issue other than how KitKat handles SDs.
I would suggest re-formatting the SD to FAT32 (on that subject, what is it presently formatted to?) and seeing if that helps. I saw a very similar thread on the HTC One (M8) forum where the person was having trouble with the phone reading content on the SD (worked fine on other devices), was blaming the KitKat rule changes, and simply formatting the card fixed it right up. Also, try a different SD card, if you have access to one.
If that doesn't work, its possible where is some software or (hopefully not) hardware issue such as a broken SD tray. But let's try to format the card and see if that does the trick.

Sorry if I didn't make myself clear... I CAN see the Ext.SD but I can NOT write... The card (2nd) it's empty and I can write in it files in my PC's Card reader which I can see in my tablet... I CAN NOT write a file or make a folder or anything when the card it is inside the tablet...
That's why I said the tablet it is almost useless as I can use only the native 16GB minus...
EDIT:
Problem SOLVED for whoever need to know how go here: http://winaero.com/blog/unlock-external-sd-card-writing-for-all-apps-in-android-4-4-kitkat/
Thank you guys for the help so far. Sorry I am a bit slow but my laptop died on me and I have been dealing with that.
I am glad to hear its more than likely just an sd card problem not the kitkat problem. I really don't want to root it. I actually adore this device and don't want to had to return it.
I have played with it more and I am getting stuff like pictures and videos taken on the device to save to sd so it is reading the sd card. It just wont read what is placed on it externally. Is is maybe that I have to tether and cant pull the sd card out?
I did reformat the sd card with the device. So it is formatted to the device. But it still wont acknowledge stuff I drop on it only stuff that is saved on it from the device itself. But I do know its working because its showing pictures I have taken with the device on the sd card in the built in file manager. So whatever it is it's not the card reader slot.
I am going to try xdm9mm's suggestion and see if that will work. If not what else should I try?
Before I can test another sd card I need to buy one (I looked and only had the one extra lying around). So what card do you guys use on it with success?
You're taking the card out and using a card reader? I think I know your problem, the same thing happened to me when swapping cards with my phone. You have to go into the system settings, and under general, select storage. From there you can unmount the microSD card before taking it out. If you don't do that, it won't read the card properly when you put it back in.

Every time I have taken it out I have used the unmount section. Originally I unmounted it put it in the adapter and plugged it into my computer. Then I dragged and dropped everything I wanted on it to it. Once I had done that I used "safely remove" on the computer and then plugged it back into the card reader on my tablet. That is when it wouldn't read anything at all. I reset it several times and finally got it to read for a minute but then when the tablet went to sleep it self deleted everything on the card. I am thinking the self deleting may be fluke because I have been able to save pictures taken by the device on it with no trouble. It just won't read anything I put on myself.
The whole thing is a bit confusing lol. I even took it to a computer shop in town but the guy had no clue what I was trying to explain. I am going to try another sd card and try tethering the device to the computer to drop in some new files. Hopefully that will help.

Hrm. Another possibility, have you tried filling up the card, say with video files, then checking from the PC to see if they all play? Most of the really cheap memory cards are fake (including on Amazon), they only have a tiny capacity, and the controller is set up to loop, so it will write the data without giving any errors, and the files will be indexed, but the data isn't actually saved anywhere.

All files on external SD card corrupt after unexpected shutdown

Hey guys and girls!
This morning my phone turned off by itself (13% battery left) and needed somewhat longer than usual to reboot (in the meantime I plugged it back in to the charger). First thing I noticed was that my whole theme got reset as well as it started showing me introductional tips ("long press here to move your apps to the homescreen, ecc.). It also started to update apps in the Play Store even though I set it to manual ... so basically a LOT of things were reset.
The biggest problem I'm having now is though that all my files (pictures, videos, music) that are stored on an external micro SD card are corrupt. It's not possible anymore to open anything. I already removed the micro SD card and put it into an adapter to have a look at the files via the laptop. But nothing, even though the sizes of the files seem OK, I can't open them.
Does anyone have a clue as to what exactly happened here? Are those files lost (at least of some I have a backup) or is there anything I can do to "repair" them? Help is really appreciated, thanks!
PS: Things like the card unmounting and re-mounting never occurred. So I can't tell if the card was dying or if actually the phone ruined my files.
Did you happen to be using a SanDisk SD Card? I've had my 10 brick 2 of those until I switched to Samsung SD Cards about a year ago and haven't had issues since.
I never could manage to recover files from the damaged SD cards.
I have a Samsung SD card and had something similar.
I guess I was on Viper Rom and basically my phone restarted around 15-20% of battery. After a long wait for booting back again, all my settings were gone.
Files and others in the SD card was okay but basically until I formatted the card, I wasn't able to boot into the Download Mode to install a new rom...
I fixed the restart issue by installing the official HTC Rom.
Thanks for your replies.
It is indeed a SanDisk 16GB card. It seems though that the card is still working (no problems accessing it via phone or laptop), just the files appear to be broken. In the meantime I also tried apps like PC Inspector File Recovery, but to no success
I'm still on stock HTC Sense by the way, no root, nothing.
Anyone know though why that happened (resetting everything, etc.)?
Hit me with a PM I'll give you a SanDisk restore tool which works quite ok. there is a huge chance some files can be recovered, some will be damaged though. Don't push any new files on the card after you tried to restore the files
HTC 10-Corrupted microSD card
I know this is an older thread, but I was wondering if there is a solution. I have an HTC 10 which has an micro SD card in it, that is "married" to the phone. When connected to a computer, the computer recognizes the phone, and the microSD card, and begins to load the folders/files. Eventually this process stalls, and the phone/drive is no longer readable by the computer. To get the computer to recognize the phone/card again, I need to restart the phone, but the same thing happens again.
I have like 20gigs of data on the card, and cannot just put the card in a reader, because it's encrypted to the phone. Any possible solutions? It's frustrating to see the files/pictures for a minute or two, and then have them disappear. I have tried copying/pasting the files while they're visible, but this often triggers the computer to no longer recognize the phone/memory card. I've tried to un-encrypt the microSD card, but the phone can't recognize/access the microSD card long enough to complete that process.
Please help if you can.
Glenn
