[Q] SD Card Not Recoginized

Hey Guys,
I am running running AOKP CM10 Nightlies on my HTC One V right now. I am running the latest sep-30 version with Jellyboot4.img. The ROM is not recognizing my SD card which makes life a bit hard. I have not read anyone else having this problem in the forums and can't post there yet because I have just signed up.
Anyone run into this problem before? Is it the ROM or is it my phone. Any work arounds? I maybe new to the forums but I have done my fair share of rooting and such and know my way around.
Advice is appreciated.
Thanks

Yeah! Me too!
I'm having the same problem, I think;
installed the CM10 CDMA Rom, used the boot.img from jellyboot5.
had the SDcard out (old 16gb from my Optimus V), tried to run Google Earth and it told me it couldn't do it without an SDCard. Put the card back in, ran GE again and it booted fine; i even saw, in Storage, that it was mounted, gave a correct number for free space/capacity. Got a 32GB micro SDHC today, shoved it in the thing--replaced the 16GB--and when i tried to download something from the web in Chrome it told me it couldn't do it without an SD card. Storage reported its presence, its empty presence. Ran something else that needed an SD Card, it reported the card's absence. Still recognized in Storage, was able to USB it and look at it from my laptop; these apps still can't acknowledge it.
Not sure why. Both cards do this.
Anybody got any idea?

Alright;
Tried formatting the card weird, waiting for the error and to reformat on the One V. just kept unmounting/mounting. Formatted it FAT32 on the PC, threw it back in.
the SDcard is visible to dropbox (for exporting) and ES File Explorer (for examining).
the SDcard is NOT visible to Chrome (for downloading) or Swiftkey's installer (for dictionary storage).
Dunno about music or gallery photos, other common SDcard stuff. Guess I'll try that next.

[Q] SD card not letting me add or delete files

I've been spending waaay to much time trying to get this phone to work as I had expected with previous phones (even my LG G2x) giving me less problems. I recently bought a Sandisk 32gb, class 10 micro sd card and after transferring old music, pictures and videos from my old LG G2x with a 16gb card, placing files from my computer back onto my S4 with the 32gb card is a nightmare! Photos are transferred but too out of order to try and deal with although it's more the music problem that has me bugging. I have some success after putting about 3gb or so onto the new*32gb sd card but after that, the sd card flips out and starts using special characters for file names. Below I attached a screenshot of what I'm going through with another app called V1 Golf for Android. I'm stuck and any help is much appreciated. I can't delete anything on my sd card nor can I add. I've reformatted this card about 4 times now without success. Some say that a Sandisk have been nothing but problems for them, you think a Samsung card could be the fix?
I'm also running windows 7 on my computer as some people have said that could interfere with the transfer but it seems like that's not the problem being that downloading apps from google play shows corrupted files depicted below.

First, did you format this 32gb sdcard using fat32, exFAT or NTFS or ?
If you did not format it with fat32 then that could have caused the problem.
First you need to remove the card from the phone and plug it into your
computer using the adaptor which came with the microsd card so it can be
tested and repaired in windows.
Once the card is plugged into the computer and it's recognized by windows make note of the drive letter.
Then open a cmd prompt in windows by going to the start menu clicking on RUN then type "CMD" and click OK to open the DOS prompt.
Then in the black DOS window type: chkdsk E: /F then press "enter" to scan and fix errors on your microsd card.
NOTE: The E: is just an example, check the actual drive letter of the sdcard which is plugged into the computer.
Please note, doing the above will not delete any files or folders unless they are deemed unusable and cannot be fixed.
The chkdsk will NOT not format your microsd card.
Good luck!

Unfortunately I ran into a very similar situation with a 64gb SanDisk card. After several months of using it successfully without issue, out of nowhere some 20 gigs of data were stuck. It seems that 1 file in a nandroid was corrupt. After formatting, re-partitioning, deleting etc, etc. with Windows 7 as well as MiniTool Partition Wizard I was unable to ever get the corrupt file to delete. Thus leaving the $60+ card useless and a prime candidate for the trash. I chalked it up too a "bizarre" instance. I have since purchased 2 64gb cards, one to replace and one for my new S4. Haven't had the issue since (knock on wood). Not sure what the exact culprit was, the recovery? (TWRP), a freak occurrance? or Just a defective card? If you have any luck saving your card please post how you did. Although I realize this probably isn't helpful except to know your not the only one.

My sd card seems to be stuck.
About 20 of 64 gb being used.
Now I can't delete anything. Or add anything.
It appears to delete and then it just comes back.
Does that mean my sd card is dead.

scandisk 64gb
Had the same thing just happen to me. Transferred a few kernel files yesterday and today couldn't delete, add or format anything. I was able to copy all files to computer but that's it.

same thing happen to my sandisk 64gb class 10 microsdcard as well
is it a virus?

I had the exact same issue with a San-disk 64gb micro sdcard, I contacted San-disk, they offered me a replacement card.I suggest you do the same, hopefully they will exchange it for you.

You can use another SD card to try whether this sd card is dead.
If anothe SD card can delete files, it proves that this sd card is dead, vice versa.

Did your problem solve? I'm experiencing now like with your problem. And I'm looking for an answer.

[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.

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.

External Memory Card Issues for Note 2

I am having issues with a Sandisk memory card on my Note 2. For whatever reason, it stopped working- like completely. I can't format it, I can't delete anything off of it, or put anything on it. I haven't write protected it either, which I found odd whenever I went to troubleshoot it on my computer. I have even tried the Command Prompt method of troubleshooting/formatting- but with no results whatsoever. I read online that ALOT of users are having the same problems with their SD Cards out of nowhere, because of an update (my phone is rooted and on 4.1.2 and hasn't been updated).
Might I also add, that when the SD Card stopped working, I noticed that there were extra files put on there that weren't originally there that are from Android (such as google.music and such) and I know I didn't put that on there. I'm just wondering if anyone has found a fix to this? I've tried everything, but I feel as if my SD card is shot (my phone automatically updates apps and such and I'm quite confident it did the same to my External SD Card as it has with other people). I just have alot of things on my phone I need to add for work, and it's super inconvenient that my phone is only 8GB and has a 60GB SD Card with the potential to work again. I would buy another card, but I wouldn't want to spend the money on one, just for something like this to happen again if you know what I mean, lol.

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.
