I copy files from the device storage to the ext sd storage. I shut off the tablet. When I turn the device back on, all the files are gone. The folder that I create for those files is still there though. Why?
My guess is you have a bad SD card, if you bought a cheap one online it may be counterfeit and extremely low quality and/or fake.

Hi I looked to see if anyone else posted about this and I couldn't find one like this. I have an evo that I have rooted. I still have the 8gb sd card. After I rooted my phone I still had about 6gb left on my sd card. After I flashed Mikfroyo 4.5, reinstalled all my apps and and put most of my games on my sd card, like I had before I flashed mikfroyo I had about 4gb left on my sdcard. Yesterday I flashed a new rom on my phone, installed most of the apps that I had, and put the same amount of apps on my sd card it went down to under 2gb. I don't see triple the amount of folders on my sd card. Does anyone know why it shows up like this or at least how to free up some room? Thanks.

Have you been deleting the ROMs from your SD card after you flash them? Each Sense rom is roughly 180-200mb. It adds up. Also, if you have been creating Nandroid backups, they too will take up a lot Space, and you need to shuffle through them and delete the old ones. Nandroid backups add up quick. I don't store my apps on the SD card, so don't know much about it, but what method are you using to do so, and are you sure they're not doubling up? I'd be more suspicious of an excess amount of nandroid backups and roms on the sd card though. It doesn't take much to fill up that stock 8gb card.
i agree you should check how many nadroid backups you have on your card, they take a lot of room, i usually move them from my phone to my pc and only leave the last one on my phone, plus they are safer on the computer. also all the zip files you use to flash roms can be moved from the sd card to the computer, once used you dont need them on the root of your sd card anymore they just waste space, i would also recommend upgrading to a 16gb sd card ebay has them for like 20 to 30 bucks and save you the trouble of worrying about memory. to move files from one sd card to another you just connect phone to pc as disk drive open my pc and right click on the drive that represents your phone, go to folder options and in views, select view hidden files. once that is done just copy all inside the sd card to a folder on your pc. then you unplug from the computer, turn off phone replace old sd with new, turn on your phone go to settings storage and unmount the sd card then format it. the plug it to your pc again in disk drive open the folder where you put all the info from the old sd and copy all that to the drive your phone represents and hit yes when it says if you like to copy and replace some files, then you are done new sd and twice the memory cv

Just switched over from an Evo 3D and swapped my old 32gb sd card. Opening the native file manager, or Astro, or es file manager have all come up empty when exploring the sd card. Weird thing is that my pictures still show up in the gallery as well as all my music in the music app but not in any file managers.
Another strange issue is that I am unable to download anything from the browser, k don't know if this is related to the sd card so I am hoping to hear if anyone figured out how to get around this. Also, I am unable to mount USB dried when plugged into the computer. I appreciate any help you guys can provide.
Try exploring external_sd. SD is the phones storage and not the card you put in.
....
I am trying to get used to this as well! I think the folder named "sdcard" should ACTUALLY be the sdcard!

Does this mean done apps that utilize the sd card will have issues or even not work at all?
same question here...i have a sub dir called /sdcard/external_sd But if you want an app to use the SD card it will use /sdcard, not the external_sd...so is it a total waste to put a microsd card into this phone, since I will only be able to utilize the space if i manually copy **** to that directory????
If you move an app to the "SD card" in the manage applications it will move it to the actual SD card. It won't put it on the internal storage.
Hello,
I transferred applications to my SD card and it worked well. I then needed to reformat my SD card. I unmounted and got it from the tablet, I copied its full content on my PC but I forgot the .* files, I put the card back in the tablet, I reformatted it in the tablet, I unmounted it and put it in my PC to restore its content, I put it back in my tablet, and I could read the card content. I however lost all applications that had been transferred to the card. I cannot find them. I transferred again another small application to the card but I cannot find it on the card, even not in .android_secure. Does anybody know where the applications are stored on the card and what happened to me. Thanks in advance for any piece of information.
I know a little bit more what happened. The applications are stored in .android_secure at the root of the card. I forgot to copy the directory, hence I lost all the applications. When I transferred after other applications to my micro-SD card, my file browser did not show them despite refreshing the directory display. I do not know why, but I found the applications in android_secure after.
I've an Samsung evo+ 256GB SD card formatted as internal storage in my HTC 10 for almost 2 years now.
2 months ago I decided to upgrade to a Samsung evo+ 256GB v2, with slightly better speeds. I simply cloned the old SD to the new one.
Everything was always fine, worked great till yesterday.
I had some weird stutters while playing music and then I noticed the UI was also getting stutterish.
Went to bed, charged my phone as I usually do. When I woke up and checked my mail the phone just froze and rebooted.
After reboot the phone told me the SD card was missing
I decided to shut down the phone and examine the SD card but the phone just got stuck shutting down, I had to force reboot and shutdown again.
I tested the SD by a full byte by byte read in Western Digital diagnostic tool for harddrives to see if my SD was broken, but it was fine, no errors.
I popped the SD back in my phone, started and the SD mounted fine, no issues so far.
Could the file system be corrupt? If it is, how do I fix it?
I could try and move the data to an external drive and reformat the SD, I've a USB 3 OTG cable. But I'm not sure how to do that either.
Will Android move the data for me automatically when removing the SD card as internal storage?
Stutters continued today unfortunately, especially when doing a SD benchmark.
I decided to use clonezilla and do a clone of the card to another one to see if that improves anything.
On the old SD I had 72MB/s read and 20MB/s write according to A1 SD bench
Internal storage 225MB/s read and 41MB/s write
On the cloned SD I have 74MB/s read and 19MB/s write
The difference is that the cloned SD is a Samsung evo+ 256GB v1 and the old one a Samsung evo+ 256GB v2
I don't get it though, doing a benchmark on a PC shows 90MB/s read and 80MB/s write.
I advice you to check media files. I had lived same problem. I found solution by chance . I attached sd card to my notebook to backup dcim and music folder. While copying the files, suddenly copy process stopped on a not special file. I removed the sd, re attached and deleted that file before continue to copy. When copying finished, i attached the sd card to phone... Whola... Without formatting or doing nothing extra the card started to work as expected
What 64GB Micro SD do you recommend to save photos and videos?
It supports up to a 1tb card. A Sandisk Extreme works well. You want a V30 rated card. I reccomend at least 256gb.
Simply format the card in the phone then leave it there. Do all data transfers through the phone.
Use the SD card as a data drive; all critical data, including music and vids goes here including everything you need to do a full reload. Redundantly backup your data drive to at least 2 hdds that are physically and electronically isolated from each other and the PC on a regular basis.
There can only be one folder with the name dcim in its name. If you create a second folder for your images to make a copy name it pics, master pics, whatever.
Only apps, the download and dcim folders go on internal memory. The left over space can be left empty or used for scratch files. If the dcim folder is here, back it up regularly to the SD card. Crashes are rare but they can happen (or damaged phones) , the SD card is almost never effected. Back it up nonetheless.
Congratulations, you now have a dual drive handheld PC.
I always suggest Samsung Pro sd cards. As for the dcim folder and the inability to change where to save the photos, i use foldersync from playstore and anything that appears in internal memory dcim folder, goes immediately to sdcard/dcim.
Also i use swiftbackup to backup daily differential every app to sd card and during the night foldersync again copies the swiftbackup backup folder from sdcard to my home nas.
