SD card problems

I am having problems with my SD card. I used to have a mytouch, and I bought a Sandisk 4GB back then. When I got the S2 back in Decemeber 2011, all i did was format the micro card to work. The S2 shows that its there under Storage, but i have always have difficulties actually using it. You will see that it has some used into it. I can only reach it through USB connection and transfer file that way. However, whenever I use any programs which can be install under SD card, it will not do so.
As you will noticed below i have a problem call App 2 SD Pro, which it will only show both memories with my phone, Storage and USB, which is the same phone memory. By no means, its finding the Micro SD card. Can anyone tell me why is this? This phone is not rooted and i have only 2.3.6.
Thank you in advance.

If you look through your list of folders under /sdcard, your micro sd is the 'external_sd" folder.

Yes that is true. Is under External SD card. My question is, why are some programs, mostly all, having difficulties to find it? and can i have all for example game files, be saved onto my "external SD Card"?

What is the speed of your sd card?
class 2, 4, 6, 8 or 10?

How would i know that? all i can see on the card is, Sandisk 2 in circle, 4GB SDHC micro. Where else can i check? which class is best?

You have a class 2. It has been my experience that when you move an app to sd card, on this phone it uses the internal "USB" storage.

So what can i do to do the opposite? Meaning, using the actual SD card instead of the internal.

[Q] SD Card Encryption

Hello. I've encrypted my sd card and have been dealing with occasional images and videos files being corrupt and not being able to be read. I have a SanDisk Ultra 64GB microSDXC Card (Class 10/U1). I've formatted this card in the phone and is now formatted using the SD Formatter using my PC but with the same outcome. Would rooting this phone have anything to do with corrupt files or could it possibly be my SD Card? Or maybe perhaps the encryption method used by the phone is just not reliable?
Any help is much appreciated.
In the meantime, I've decrypted my phone so let's see if there are any reliability changes.

Update: I got a new replacement and have the same damn problem. I have turned off SD Card encryption and it has been good so far.
Could you please suggest something equivalent in the event my phone is lost or stolen? I have TrustGo installed and do believe it can wipe my phone but not the data on the SD card.

Hello,
There is a chance to recover data with software for cardrecovery. You can find it on google like memory card recovery after format.

Your may try out recuva. Use this via a card reader.

getdataback is useful also. used 2 times for note 2 without problems.

[Q] sd card not mounting for anyone else?

I've been having problems with the external sd card, when i restart it shows 'sd card inserted' in the notification panel but under storage the only options are mount sd and erase sd. Its a generic 128gb sd which i formatted on the computer and the phone, when i hit mount sd it just shows the 'sd card inserted' again but doesn't actually mount. It only works if i format it in the phone and only until a restart. The card works perfectly on my computer. Anyone else having this issue or have a solution, there has to be something quicker than copy, re format and copy back the files

what type of computer did you format it on? in the past I had issues with formatting my SD cards on windows. I either had to format with the phone, a mac, or a linux pc.
I have not had the issue you are describing, but my card does unmount sometimes and then remounts immediately after.

Windows pc, but i reformatted it on the after it didn't mount, could it be the sd card? It was 14$ on ebay but the sellers feedback was 100% for the cards.
I'm wondering if it might be a problem with the reader or the firmware since it reads on the pc just fine.

I actually had a 64GB SanDisk MicroSD card unmount while in use on my G3 then I could never use it again. I'd try to format it and it'd act like it did but the same files/folders were there. I could no longer write to it. I need to still contact SanDisk about it to see if I can get a replacement.

You need to reformat it into NTFS format.
Then try to mount it. This is the case for anything 64g or higher.

potentional fix
I had this problem with my LGG3 not mounting the SD card, I found that taking putting the SD card into your pc/laptlaptop, copy over pictures and music you wish to keep and format it as a FAT32 this worked for me however the Android files on the card had to be deleted I think on of them was corrupting the SD card as it would show randomly on my phone.
Hope this helps
