[Q] External sd problems

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.

SanDisc 64 GB mSD might cause initial problems

I ordered a 64 GB mSD from SanDisk since they work nicely in my SGS III and Note.
I just took them out of he blister, inserted into the devices and worked right on.
Now in my SGN 10.1 I inserted the mSD, it was shortly recognized but immediately notified as "ejected safely". No hint what to do, no options presented (format)
Checked mSD then in my Note and it said: unformatted ext SD.
I formatted the new 64 GB mSD in my Note then placed it back in my Note 10.1 and it works like charm (59 GB available)
Just to inform You in case the same happens to You .......,.,

Cool, I just bought a 64gb card from yesterdays Amazon blowout and will try to format it in my SGSII before using in the Note 10.1!

Have you tried adding/removing files up to 59GB but at least 32GB to confirm that it works correctly and not just giving a false impression that it's working below 33GB?

Jep, filled it up with my DivX movie collection + my pic file archive filling 46 GB ..........

HOw do you format using the note? I got mine from my inifinity dock (64g sandisk class 10) and just got my note and inserted the sdcard I did a half format on the computer to exFAT but it was taking too long.... then I reinserted it to the note, it showed unsupported type and asked if I wanted to format.... I click YES and there is no indicator that the card is being formatted.. So I hit the sdcard notification again and it asks if I want to format.. and samething. Am I doing something wrong?

Hope you didnt kill it by taking it out before it finished. I would never remove any card or drive in the middle of a format. You may need to format it on your computer. Hope you get it working.

Is the Note 10.1 reading the card in exFAT and are you able to store individual files over 4GB on the card? I had to re-format my SanDisk 64GB card in FAT to get it to be read by the Note. I'll go format the card in a Note or SGS3 floor model at the AT&T store if it'll get the Note 10.1 to see it as exFAT.

Did the Note 10.1 recognize the card as exFAT by itself or did you put it in another Samsung device like the SGS3 or Note first? If it recognized it by itself, what firmware are you running? You can find it in about device in settings.

Excellent. That means the missing exFAT native support will be released eventually. LH1 for Malaysia has a package date of August. I'm on LG5 for Brazil and the package date is July which is why exFAT doesn't work for me.

The same thing happened to me and it drove me crazy. This is what I ended up doing (from another thread). Some folks have just re-formatted to FAT32 using EaseUS without cloning.
BarryH_GEG said:
It's a total PITA. If you have another Android device with a MicroSD slot you can try formatting the card in that device first. A lot of people have had luck that way. I tried reformatting a 64GB SanDisk card to FAT using multiple different programs and the Note still wouldn't mount the card or give me the formattng option. Here's the solution, I know it's stupid.
1) Download EaseUS Partition Manager (it's free) - http://www.partition-tool.com/landing/home-download.htm
2) Take a blank FAT MicroSD card and mount it to your PC
3) Have the 64GB mounted at the same time so it too shows up on your PC
4) Using the clone wizard, clone the FAT card to the 64GB card. Make sure to expand the size of the 64GB card before cloning so it doesn't pick up the size of the smaller card.

EaseUS was alot easier to use than the one I used fat32format (cmd mode). Im transferring some of the movies I have on file, but some movies are failing to copy like mkv extensions when the sdcard is in the tablet. But copying mvk movies directly to the sdcard is fine and the tablet can play it... wierd

Junrider's coming from Asus so that's Chinese. Here's a link to the rooting instructions for the OG 10.1. Follow them but rather than using the custom files suggested for rooting purposes, use the download of the Note 10.1 OTA that got pulled. The first link below also has a d/l link for Odin 1.85. It's a harmless process and since it's official s/w you'll have no problem receiving future updates either OTA or via Kies. As far as I know the only issue with the update were some changes in S-Note that not everyone thought were beneficial. I have a N-8000 but think that my version of S-Note is the same as the one people in the U.S. got via the update. I'm fine with it. If there's other issues somebody please chime in.

[Q] Frustrating SD Card issue - not the normal

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.

Using exFAT on Stock 10.4.B.0.569 without mod at all.

Hello all.
Just got a class 10 MicroSD XC 64GB fot my Xperia Z C6603 and saw many post about exFAT not supported. Luckily, mine works with no fuss at all. So I'll post it for reference as I didn't see anyone mention this.
- First of all, I format the card with SD Formatter 4.0 from SD Association itself. Set it to exFAT. Should be done quick.
- Then I replace my old 8GB with this 64 GB(59 GB actually...) and start with SETTINGS > STORAGE > TRANSFER DATA TO SD CARD to test if it can write, and yes, it just work.
- Then I set USB Connectivity to MSC mode and plug into my PC. Windows Explorer says it's exFAT. So I put an 12 GB movie file in. It just work. Play in MX Player with no fuss at all.
Wish this useful and happy new year!

As far as I know, exfat has been supported since 4.2.2 on our device.

Oops... My bad.

My xz cannot mount 64gb sandisk exfat format. When im insert the sd,it say sdcard removes insert new. Im on stock 4.3 rom with alnikki v19 kernel. Any help?
Sory for my bad english.still learning.

Stock kernel supports exfat filesystem out-of-the-box (on stock unrooted ROMs). Maybe your custom kernel doesn't have exfat support. Go back to stock kernel and you'll find your card is mounted and readable.
Dead Cookies leave no trails...

will try to flash back stock kernel. thanks for your help.

How to rename my external SD card?

When I moved my 128gb card from my Note3 instead of extSdCard it for some weird reason named it 18fa-adfa. It's there a way to rename it. I have Busy box installed, I just need to know the steps to do it. I tried using ES Explorer but got a task failure.
Worst case please tell me how to do a symbolic link.

Did you try putting the microsd card in an sdcard adapter and inserting into a card reader on the pc? This will show as a drive letter and should allow you to rename or format the microsd card.

No way to rename the microSD, it's a new Android 6 feature: it refers to the microSD using some unique ID, not by the label.
But generally there are other ways to access the SD content, for ex. using /mnt/external_sd or similar

After having received and configured my new S7E I unfortunately must confirm what you said... in the Samsung's MM there are no friendly names referring to the microSD under /mnt nor under /storage, like in other MM smartphones...

There must be a way to symlnk a name? We need a small app for that. I'm sure rooting is required.
That is the 2nd thing Sammy messed up on, the 2nd is they are defaulting to Always on multi app pop up choosers. It is horrible.

I just put the card in a SD card adaptor and renamed it on Windows.
Works fine on my S7 G935F with encripted SD card.

any update on this? I received my S7E and I hate this MM naming....

Bump.
Same problem here. Some file managers see it as Media Card, some as SDcard, but the majority see it as "random combinations of numbers and letters" that is identifiable to the card otherwise. More annoyingly, some file managers see it as both and treat it as 2 different SD cards each requiring their own permission. Galaxy S7 Verizon using SanDisk 64GB, Samsung 64GB and Samsung 128GB. Same results.

I thought that quote was hilarious! :laugh: I guess everyone in this thread is too young to have ever used DOS or maybe even the Windows command prompt. This "unique ID" has been around for years. It's simply the Volume ID stored in the boot sector. It can be changed easily on NTFS and FAT32 boot records using a disk editor, Sysinternal's VolumeID utility or with the HardDiskSerialNumberChanger program. The problem with exFAT is that there is a checksum stored and if the boot sector is changed, Windows and Android will think the SD card is corrupt. Use Rufus to format it to FAT32 and you'll be able to change the Volume ID to whatever you want.

I'm actually using exFAT, for me there are no chances on Android for the slow proprietary NTFS or the obsolete FAT32...
If I understand well, are you really going to use FAT32 on a 128 GB microSD used to store 4K recordings and videos?

I was just saying that if you want to change the Volume ID, you're going to have to format the card in FAT32. I don't know if any Android phones support NTFS. When I had MBR hard drives, I used to change the Volume ID's on them so that's why I said it can be done on NTFS.
On my Sony Xperia M4 I'm currently using exFAT, but my LG phones only support FAT32, so I did use Rufus to format the 64 GB SDXC cards to FAT32 for them. I don't need to store anything over 4 GB and FAT32 is much more compatible if I have to use the card in other devices, like my pre-Cinavia Blu-ray player. My phone isn't capable of 4K recording and most apps probably don't write files larger than 4 GB since there are still a lot of phones in use that don't support exFAT at all.
In my opinion, it's good that Android 6 supports the Volume ID, especially if you switch out SD cards, because then an app won't accidentally overwrite data on the wrong card.

I've been using exFAT formatted microSD on all my phones since Lollipop cause AFAIK exFAT access should be faster then FAT32.
Even my latest microSD (Lexar microSDXC, 128 GB, 1800x, UHS-II) comes from factory already formatted in exFAT.
Moreover, exFAT is natively compatible with Windows at least since version 8, no special drivers or utilities needed, even exFAT formatting new media is possible within those Windows versions.
So, whenever possible, IMHO is wiser to use exFAT on latest Android versions.
