Hi guys
I'm having some extremely irritating problems with my A500. It doesn't detect any external sd card I've tried so far. It says external sd is unavailable under storage in settings and the external_sd folder is empty in root/mnt. I've tried 3 different cards so far with no success. Anyone have a any advice for me on how to mount the card? I think the problem might be that it doesn't get mounted when I insert it. I can't root because the GingerBreak mod that's been posted needs an external card to work. So maybe some advice on how to root some other way? Then I can try restore a stock image and see what happens.
I had to insert mine and then reboot the tablet for mine to show inside of a file manager.

Hey, thanks for the tip. I forgot to add it to my original post. I've tried rebooting with all 3 of the cards I have. I'm starting to think it's a hardware problem...
Have the cards you're testing been formatted NTFS or FAT32? If NTFS they probably won't work without some help.
The stock device only deals with FAT32 mSD cards; I haven't tried the NTFSMount app from the Dev forum on an NTFS-formatted card yet, only USB devices.

Hey. I've formatted the cards multiple times, to FAT32 every time. Might try exFAT tomorrow just to see what happens.
exFAT didn't work. Not that I expected it to, lol. Maybe the GingerBreak apk can be modified to use the usb storage instead of the external sd. Any idea where I can get the source code to take a look at?
If you've tried multiple cards, all FAT32 and all work on other devices, I'd return the tablet while you can, sounds like a hardware problem indeed
Slight problem with the returning, lol. I live in South Africa and ordered my tab from the USA since my own country is so backwards. I don't really mind not having an external sd card, I just wanna root again since almost all the apps I use need root. I'm considering returning, even if it's gonna take a lot of effort, time and money...
EDIT - Another reason I can't return it (and this is a horrible thing) is that SuperUser Permissions is still installed. The recent update made me lose root. So I'm kinda stuck with this app that's proof that I voided my warranty. The only way to get rid of SuperUser is to use some apps that all need root. To get root I need the external sd to work. To get that to work I need to send it for repairs. A very messed up situation
I'm almost positive that it's a hardware issue now. Even when I try to do an update.zip from recovery mode it can't find the file even though it's on the card. Let's hope they don't see the SuperUser app when I return it...
I thought about maybe waiting for Acer to release an update that will unlock the bootloader. But since the SD card slot isn't working I won't be able to install the update. That so much depends on one little slot amazes me. If you wanna know what the single point of failure for an Android device is, look no further.
I know some android tabs came out without external SD card support. I live in the uk and have a 32GB version and the SD card worked out the box. Maybe you have to wait for an update. Just my 2c though. You won't need an external SD to receive OTA updates though.

Here's an image of what recovery mode says when I select Install Update from external source. Seems the system can't mount the card. Sigh
I like that message at the end.... "Install from sdcard complete."
You had rooted before the update, which means it had to have seen the sdcard then. So it's unlikely that the hardware just went bad. Are the sdcards your trying of different sizes, classes, and/or manufacturer?
I'd go with the same sdcard you used when you rooted before and reformat it using the HP USB Format tool. Selecting fat32, of course. And don't select quick format. See if that helps. Sorry if I missed somethiing relevent above.
Here's the link to the HP first tool. http://download.cnet.com/HP-USB-Disk-Storage-Format-Tool/3000-2094_4-10974082.html

Lol, the "fake it till you make it" strategy. Fail Google.
I've tried it with the original SD and two other ones. My guess is some app tried to mount the external SD in /mnt/sdcard and messed up some associations or dependencies or something.
I'm amazed. After everything I've tried it suddenly worked. I was busy in settings and accidentally selected storage. And there it was in all its glory... A working external sd card! I'm rooted again, backed up and ready to roll!
To anyone finding this thread hoping for answers for a similar problem: It was a hardware problem indeed. I fixed it myself by opening the tab and bending the MicroSD slot's pins back into place.
Note - this is not the "Damaged SD card Issue" i never received ths warning.
Up until last night, my New S4 was running great with my Samsung 64gb sd card...had a ton of programs etc. The thing is, the card was also encrypted by company security policy. Prior to flashing to a new rom i tried to decrypt the card, the the system credientials were locked and wouldn't let me (after removing accounts etc). I don't want to talk about ways i could have decrypted - let's just say i went into the flash with an encrypted card.
Wiped cache, delvik cache, and factory reset
now i don't believe this cleans the internal (SD or storage) as this is where i flashed from
Everything flashed successfully and the new rom is up and running.
Except now i can't access my SD card on my Galaxy. Mounting only results in the device saying "it's safe for removal". I can't even format on this device, but i can on a galaxy s3 and my laptop. And the card works in all those places just fine. The card won't even mount in CWM....EVERY time I insert the card, I'm just told the card being checked for errors and immediately goes to "card is safe for removal"
anyone know what might be going on? This is driving me nuts here!
Just tried reflashing again, this time clearing internal memory too...installing rom from a diffetent external SD card and still no luck. Same result as above.
Again SD card works in all other devices other than s4.
Also note I am using a T MO rom on att device with new kernal. I don't think that should matter though

Had this issue. I used my 64gb card with the stock rom. I flashed CM10.1 this morning onto it and CM10.1 wouldn't read it. Took it out, put it in a SD card adapter and read it on my laptop, copied all contents off. Put it back in my S4, formatted it. It worked. Put card back in laptop, copied content over, worked fine on the S4.
It's a formatting issue. Just back up your data via another device, then format the card in your S4 and youll be fine.
Problem is I can't get s4 to the point where it will format the card. After I attempt to mount it...keeps reverting back to ready to remove message...as if it doesn't want to know the card is there.

Well. Try formatting it in another system. Take it out copy your files off, then format it. (Windows My Computer, right click the flash card, Format). Mac, Applications>Utilities>Disk Utility Select the flash drive, go to erase. Linux, use Gparted. Install via sudo apt-get install gparted if your on a ubuntu/debian based distro.. Then try it in your S4 and see what happens. Maybe the partition got messed up and the S4 is goofing up when it goes to read it, or check partition table or something in a way where other systems might be okay with it still.

Thanks for the input. I did try as you recommended. Even going so far as to format in a galaxy s3- successfully ....a digital camera - successfully ...and my computer systems successfully....all able to read write and format.....galaxy s4 just doesn't seem to care....

Interesting. Well eliminated anything with the card itself or formating.
Have you tried any other microSD's in your S4?
If not I suggest trying that and see what's going on.
If it DOES work then it might be a issue with the card. If it doesn't, something with your S4.
It's either hardware (the microSD card reader is bad somehow) or software (Something in your ROM is messed up). If you want to troubleshoot it to the fullest extent you can do a full factory restore, wiping your phone completely, and loading stock firmware again and wiping \Data partition, as well as cache and see what happens. That would eliminate any software issue.
I have tried other cards and they all work fine. S4 can do everything with these cards. Format...mount...unmount....etc...
Just seems to be this one card in this one device....both card and device work well outside of each other...

There's your problem then. That brand card or something, or that particular card may have something funny going on with it.
I had the same exact thing happen to me yesterday. I was also having issues with my WiFi not working either.
I ended up doing a complete wipe of my S4 in cwm, Odin to stock, updating my software via settings and re-rooting. After doing that my WiFi worked and it would read the 64GB SD card I had.
Luckily, I had a nandroid backup from just a few days prior I was able to revert back to.

Aokp/aosp/cm roms/kernels don't support the exfat format.. So format the SD card to FAT32 to fix the issue check this out.. Lots of threads on this.

Your 64gb sd card is Exfat and a lot of kernels and roms do not support this. Format it to Fat32 and all should be good. But backup everything on your sd card before you do it
don't know how far you have gotten on this, but
i usually use sdformatter from web. i do a "full erase on", takes awhile, but cleans card well and always solved any card issues i had--
Final Solution Atrix 4g to the rescue
Finally put the SD card in my old atrix 4G and reformatted twice and now the card works!
Can't for the life of me figure out why nothing else could format the car sufficiently.
I struggled with this as well just now with my SanDisk 64gb card on my Verizon s4 running Jelly Beans... Solution was to format the card fat32. I did this by executing this file from the command line and issuing 'fat32format x:' after mounting the card obviously. Here is the file fat32format.exe It works perfect now Note: Don't format the card again on your phone or it will end up exFat and the phone will reject the card again.
Sometime after I installed safestrap and a second rom, I lost the ability to write or delete from my external SD card. It may have something to do with SAFESTRAP, or possibly an app called SDFix: KitKat Writable MicrosSD which I installed and may have ran in preparation for any type of KitKat update. Anyone have any ideas of what I may have done?
edit for more info : The weird thing is, it lets me go through the motions to delete a movie file with say ES File Explorer, but when I reboot, the file is still there and I am able to watch the same exact file I thought I deleted. Also, if I set my camera to write external, it seems like it works, but when I reboot, the files aren't there anymore. Luckily the few pictures I tried taking like that were uploaded to my dropbox before I reboot..... Also, if I create a new folder and paste a file into there, the folder won't be there when I reboot. Also, it seems like my titanium backup files aren't updating, they all seem to be dated February 28 and they won't update even though it goes through the entire backup process!

That is a good idea. I'll try once my co-worker comes back from lunch so I can borrow their microsd-usb adapter.

The card is an 64GB Sandisk, and the computer won't recognize it, I believe because of the way it is formatted. When I get home, I will try to connect via USB 3.0 and see if I can dump everything to my PC and go from there....

Your computer should still recognize it though.
uhh ohh, its a VDI virtual system, and it says this card needs to be formatted before windows can recognize it....
I am copying everything over to my PC over USB. I will try the card in a card reader to see what can be done. If I format it, and if it works after format, should I have confidence that the card won't crap out on me in the future¿???
I am finally able to format it using a slow format in Windows 7, lets see if it works...
Nope, still broken with all previous files in tact.
I'm having the exact same issue and I bet others are too. At first I thought it was something to do with an ESexplorer update since I never happened before it, but I've deleted ES and tried many other file managers/explorers and still have it happen. Someone has to know how to fix this.

I had the same issue with the same card. After a lot of research I found that my SD card had somehow become locked...I know...WHAT? My sd card is looked with no way to unlock it. I can view files on it but i cannot add files or delete from the card.
I emailed Sandisk asking them if they had a solution but I never heard back from them
I have tried every solution that I have found and none have worked...
I've gone through 6 San disk 64gb class 10 cards between my Note 2 and Note 3 with my last cropping out 2 weeks ago. San disk will replace your card and tell you to contact the phone manufacturer. I did that contacted Samsung...at 1st I got the run around but I was persistent and got a hold of a good tech support agent. Samsung phones have issues writing info to the 64gb class 10 cards. They are aware of the issue and are working on a fix as of 2-3months ago. He told me the will work fine. He said they don't recommend over 32gb and a class 4 card because of the stability issues of files being corrupted on class 10s particularly 64gb 1s. Funny thing is i called San Disk back and told them what i was told and asked for a 32gb lower class and he told me i could buy it buy they could only replace it with the same one i had. Good luck!

You know this is not the first time that I've heard of this. I actually had a 10s 32Gig SanDisk micro that I ended up losing because of this problem with my Galaxy S3. I got to work one day and set my phone down on the desk and it just seeming stopped working. I don't know what it is with the 10 series cards but it seems like they all have some kind of problem.
Thanks everyone for all the info. I guess I'll have to get another card and I'm going to be sure it's NOT another SanDisk.
I have a strange problem with my note3 n9005 that is running omega v.16
Lately when I install an app from play store it works great until I reboot the device.. After I reboot the app I just installed is gone and I have to install it again..
My old apps that I have installed before this problem started occurring are just fine, and does not disappear after a reboot.
Does anyone know why this is happening, and if there is a way to fix it?
Thanks in advance

I just checked, and you where right.. Some apps seems to automatically install on the external SD card, I moved it to device storage and it was still there after a reboot..
Many thanks my friend.
Now that leads me to my next question..
Sense many apps are installed to external SD and seems to work just fine even after a reboot, why doesn't any new apps stay there anymore?
I don't remember changing anything..
Is there a way to make it work again?
Thanks again
To be honest with you I'm not sure. I do know android has made some changes in KitKat in regards to the external SD card not being able to write/read for 3rd party apps. There was a fix for this somewhere on XDA. Now the question is, if this is related? Couldn't tell you. Only advice I can give is, leave your apps installed in your internal memory. Keep everything else for your external SD. Glad I could help!!

Yo. I may shed some light in this situation.
Get a new external SD card - 'tis what I did.
I had this 64GB SanDisk UHS-1 Class 10 - exactly what you have: http://www.sandisk.com/products/memory-cards/microsd/ultra-class10-for-android/
One day when I took out my MicroSD from my phone and put it back in. I thought everything was fine. During transfer it transferred things to my computer, but then it kept freezing up. My ROM file (250mb) was transferred somehow into my MicroSD along with the Google Apps zip. When I turned off my phone, preparing the ROM flash, I only saw my ROM file and not my Google Apps file. I thought "that was strange" and I did it again, by deleting both files just in case of MD5 mismatch. This time both files confirmed inside the MicroSD, I rebooted. No Gapps showed but my ROM showed, so I tried to install it (note I deleted this file already) and it said ERROR. I plugged it back into my computer, Google Apps was not there, but my other files like photos, music, app data still remained. One peculiar file popped up, was my ROM file. It was 20kb. I deleted it. Rebooted my phone, plugged it in. It appeared again.
Seems like my microSD entered a stage of read-only but it isn't actually read-only. Like it doesn't retain any information AT ALL. My MicroSD can't be touched, I tried deleting 13gb. Windows showed the data actually getting deleted with the bar (and it fluctuates in data I/O speeds!). Unplugged. Rebooted. Plugged back in. 13gb worth of files still there, in tact. Like a visual storage to fool people you can delete files but in fact you can't.
I tried it on my Note 1 (FAIL), Note 3 (FAIL). The only way I could read the extSD was to plug it in a microSD adapter and transfer files out of it. At least Sandisk thought of a failsafe read-only phase to back up files. Instead of breaking down completely.

You are absolutely right.. I checked the card buy putting it in my computer, and it was as you said in a read only state..
I was able to copy my things from the card, but I could not put anything on it.. I could not even delete anything or format it!
So I went to the store where I purchased it, and now I have a brand new Samsung UHS-I 64 GB.. Hopefully this one will last me longer.
Buy the way, it turned out that I purchased the card on July 17 last year, so had I been waiting for just 6 more days, I would not have been able to have it replaced.. So I owe you many thanks.

1 year warranty ?
AFAIK it is a lifetime warranty if from sandisk. hehehe. I might be wrong.
but the Samsung SD card is good. I have it, and works well.
The 64gb sandisk yes got problem. I have it as well with the problem
Hi Guys,
I'm on Temasek's CM11, been using this Sony 64GB microSD card for over a year, and today, randomly while the phone was in use, I saw a message pop up, SD card unexpectedly unmounted. After that, it's not using up in the file systems, all the way down to the Recovery. I'm using TWRP.
I put the SD card in another Note 3 I have and everything seems to be fine on there, all the data is here.
So just posting here to make sure that is it safe to conclude that my SD card slot is fried?
And if so... What are my options... I have had the Note 3 for over a year and brought it off of Craigslist. It's unlocked and use it on AT&T...
So any ideas or advice friends? And yes, I pressed the SD card firmly in my Note 3 many times...
Thank you!
Unless you smell ozone or see burn marks it is not fried.
Hi Gary,
Thanks for your response! Definitely no smell, no burns. But, SD card is not visible even in TWRP recovery, but works great in another Note 3 I have.
Can you, or anyone else recommend what I can try before I conclude it's a hardware issue?
Would appreciate any help guys!
Thank you!
It is probably your ROM. If it is working on another phone, then nothing wrong with card. Hardly doubt it's hardware, but never know.
How about trying another card in your phone and see if have same issues.
Have you tried another SD card?

Yes guys, tried another sd card, same result, but the card reads fine in the other phone. Even the second card. Remember, the sd cards are not showing in Recovery either... that sounds like a (hardware) problem ...?
No idea. Have you tried saving all your files from SD card (to computer), then format that sd card ...see if it helps.
If not, then it could well be hardware. If you can find a phone repair shop (not official samsung one), then they can probably replace it.
I don't think any official Samsung one will do it for you (since phone is modified), but can try lol.
Good luck!
