galaxy S4 microsd card problem

Hello

I have SanDisk 64gb microsd. I have not done anything to the phone and now periodically the phone stops reading the 64gb card .It does not say unmounted just when I check gallery the photos are not there and I have to restart the phone.


I have a rooted 4.3 ROM..The only thing I can think of is ES file explorer potentially caused issues. I noticed things acting weird after I used it when I do heavily.


Please help. Any and all advice welcome. Thanks

Tried to re flash a nandroid still issues. I noticed in general my touchwiz is running so slow. I flashed sacs red theme about a month ago. Not sure if that had anything to do with it. Should not have.

It will reread it when I remount it or reboot. Not sure specifically what is causing it though.

I searched on Google and there is not really a concise answer as to why this happens. It is a very ambigious issue, however; it seems to be a reoccuring issue with SanDisk cards and 4.4 KitKat ROMs.

What I did was completely flush out and re-installed both custom recovery and my ROM to 4.2.2

It is disappointing because I really like my Samsung Galaxy S4 phone and you'd think upgrades mean better quality product when it has not. 4.4 KitKat ROM is not that good. I don't like both CM and TW versions of KK. One feature I do not like with TW KitKat is the inability to hide icons. There are also issues with battery drain and free hotspot mod.

I don't know what is going on. When I plug my phone into the computer I can access the SD card. When I check the phone it is not reading the SD card. Don't know what the problem is.

What I will do is try and format the SD card with the phone, then put everything back on. So far, I have isolated it to ESFile explorer. Initially I did not update the apk and thought that would work. It did not.

Here's what has happened:

I use ESFile explorer to access the SD card. Then when I went into clockworkmod, I tried to delete a nandroid copy I made. It says 'failed to delete'.

Then the ROM and sdCard do not work correctly anymore, so I have to wipe and re-flash an old nandroid.

Makes me wonder if something is corrupted in the SD Card. Everything used to work fine, but now whenever I access the SD Card with ESFile explorer, even the old version of it, it causes issue.

Can you explain how you did this ? So an update on my situation. I can read the sd card but it will not format and nothing can be written to the card. I tried using recovery and touchwiz to format and it fails.

Can access what is on there but cannot write or format anymore. Any ideas ? At this point I swapped to a new SanDisk card I had lying around. Don't know what to do with the old card
