I am stil on stock ROM 3588 with no mods. I have a few apps installed mainly games. I installed a 32 GB micro SD card. I have used the adapter to add music, video, DOC and PDF files. All files were added to new separate folders. I put card in with tablet off an then turn on. Nearly all folders and files end up in "lost.dir". I do get few music folders and files but 98% are gone. Am I doing this the wrong way or a way to correct this?
Does any ROM allow you to choose where to store downloads, internal vs exernal or installed apps to internal vs external memory?
I think the device only accepts up to 16GB MicroSD cards.
Thanks for responding Yarsis. I have read that several are successfully using the 32 GB cards.
Does anyone know if there is a difference between PC vs tablet formatting?
Hi,
I'm pretty sure the cards needs to be formated as FAT32 and at 2048 bytes. The issue you mention has been reported but as far as I recall proper formating should fix this.

hi,
i am using htc incredible s.some days ago i tried to make folders in my 8 gb kingston like for movies,songs etc.but to my surprise when i changed from disk drive option to charge only,i culdnot find any video or could play previous videos using mx video player.i again changed the option to disk drive and saw that there was no folder there and lost dir had all the files.any how i changed the card and bought 32gb kingston.but the problem is same.and once this problem araises,i cannot play any video file except which i have made from its camera.i am so depressed here that i am thinking of selling my phone
i am using the stock rom 2.3.5 gingerbread.plz help me out.
no help from any 1
i figured out the problem.but again a little confused.my sd caed doesnt seem to work properly.how to check and fix the sd card?
I think corrupted or "lost" files go in that folder. Did you unmount the card on the PC before switching from disk storage to charge only on android?

I think You may try to use formating tool from this site www.sdcard.org It usually helps with bigger SD cards.
Worth to try I think.
Connect your phone to your computer in mass storage mode, or preferably use a card reader and copy all your data from SD card to a backup folder. Format your SD card to FAT32 with 32kB cluster size. You can use the normal right click>format option in Windows/Linux/Mac. Uncheck Quick Format (in Windows) and let it do a full format. It'll take around 20-30 minutes for a 16GB card. This will fix any filesystem errors that are causing data loss. Once that's done, copy back all your data as it is back to the SD card. Now your card should work fine for a long time. SD cards tend to get corrupted over time, especially with Android, so doing this once in a while is helpful, whenever your card gives you any problem. I have had this same problem a few times and this fixed it for me.
I have data corruption on sd too but it happens often to data of any type/size and I believe that the corrupted data are moved to LOST.DIR They have no extension and cannot be opened or recognized. So I'm losing apps, photos, videos, anything. My device is an LG P500 and the sd card is a Transcend 4gb class 6.
What cluster size do you recommend for a 4 gb sd? 4kb is the default for its size and I believe that 32kb is too much for such a small card.
Hi guys I am new to android and I got myself a Micromax A110 running on android ics with 2 gb of internal SD card memory...
As you guys can figure, the internal memory just isn't enough for installing heavy games and storing and downloading large videos and music, so I added a 32 gb external micro SD card.. the card shows in my file manager and its contents are accessible, most apps like ttpod, ttorrent, vlc, chrome etc don't detect my external card. They only access the contents of my internal SD card, download to it.. I can't set the default directory to the external card...
When I installed nfs most wanted to my phone, it asked me to free up data in my SD card or insert another one as there was no space left due to obvious reasons of my internal SD card being filled with other apps.. I uninstalled and reinstalled it after setting the default storage location to the external storage... I found that the game installed in the internal storage this time and on startup, it gave the same message..
Is it a common problem or a limitation to the OS? Is there a work around for this? If so how? Does my phone needs to be rooted for the purpose? Please help as the problem is getting annoying.. my external card is lying almost empty...
Thanks in advance,
Extremely sorry for the long post...

It's because Google made the stupid decision, starting with Honeycomb (which is why the Motorola Xoom, the first Honeycomb device needed an update to enable use of it's MicroSD card slot) to merge the /data/ and /sdcard/ partitions. What that means is that the SD card becomes a virtual space (a folder, in fact) located in the same place where all your apps are stored. Why is it stupid? If you have a phone that actually has a MicroSD card slot, like yours or the Galaxy S III, the MicroSD card becomes a different "folder" (something like /sdext/, which stands for either extension or external). Only apps that specifically are programmed to look for that mount point/folder will be able to use it. Most music/video/picture players/viewers can, because it makes sense to automatically program to do that. But with large games, like you said, NFS Most Wanted (which I also have), it sucks because the game is like 2GB.
My Galaxy S3 has 16GB internal and a 32GB card. I'm forced to use the internal storage only for large games because they don't see the memory card. It sucks. The good thing about merging /data/ and /sdcard/ is that it simplifies things, like on the iPhone where your space is your space, no matter how you use it. It used to be that you had like 1GB or 2GB for apps (the APK files only, not the files that games download for example) (which the HTC One X does, but still only uses internal storage because there's no card slot), and the rest went to your MicroSD card slot. Now it's all to internal storage because your internal storage IS your MicroSD card slot at system level.

Hey man! Thanks for the reply....
Can you tell me how to work out a solution for this?
Is directory bind or fstab file hack the only solution?
Is it possible to overcome this without root?
And some apps do detect my Micro SD card... It is in the directory mnt/sdcard2
Please post questions one time only and in the proper Q&A section.

I have bought a SanDisk Ultra 64 GB microSDXC (Class 10, UHS-I) and put it into my new S3 (16 GB, black):
In "Settings" the Card gets detected and shows its correct size (59GB)
When plugging the SD Card into my Notebook, it's shown as 64 GB device, also
When pluggin the Phone with inserted SD card to the PC via USB, two new drives are shown for the internal and the external space of my phone. They contain different files, but have both the same size (11GB)
Therefore, i am unable to use the 64GB of my external card. I guess it does not get mounted properly. Instead the extSdCard folder seems to be located at the internal space.
Do you need more detailed information for helping me to solve this issue?

/edit: I forgot to mention that after not being able to solve this, i rooted my phone. But nothing changed.

Cant download anything bigger than 4gb to external sd card. I have a T769 Blaze and have a 32gb external sd card installed, a sandisk hicap. I installed it factory and no luck. Read some forums and formated it to exfat, then ntsf, both read fine and can store up to 4gb but no more, tried all the various apps to get it to store when downloading but always get size limit error. How can I get my OS to allow bigger than 4gb to download to my 32gb sd card. Note: I have no issues when trying to move files from PC to phone, just downloading them from the Internet either by download site or torrent. Got some movies and software I need to get. OS is ics 4.0.4 rooted stock. I am a good pc geek but limited on android/linux skills.
Strange.

If you used an NTFS formatted SD card, you should be able to put a > 4GB file on there without trouble. You may have formatted the card as vFAT instead on NTFS. The problem would then be that your phone wouldn't be able to read and write to the NTFS file system (your PC would have no problem). The only file system that Android can read/write to that handles files larger than 4GB is Ext2/3/4. Of course, that means that your computer will have to have special software to read/write an Ext2/3/4 file system (unless you are running Linux on your PC, or you have a Mac). You can move the files from PC to Phone because you are probably writing to the phone's internal storage which is Ext4, and the MTP protocol is handling the file system issue that you would normally have if you tried to write to the file system directly.
Good luck, let me know if you need anything else.

So if I forrmat my sd cart to exr4, I'll be able to downlod torrents up to 4gb? Correct?
Hi P9000 users!
I had now time to test some stuff with my P9000. One question: I inserted a Sandisk 128 GB SDXC Card (UHS) and formatted as internal Storage (want to move apps). Worked fine for the Phone and i was able to move apps to the SD. But after connecting Phone to USB (via MTP & unlocked phone) it only shows 32 GB internal SD. Also via File Explorer app on the phone i cannot find the external SD or mountpoint....
Anyone with same issue? I also changed connection-type to USB and then my OS (Win 10) does not open phone file system at all.
thx and br

We did an article about the SD card memory management in Marshmallow a while ago on the XDA portal that explains this, I'd suggest googling for it as I can't remember the title.
Edit: Something to do with the SD card being formatted as Ext4 (linux file system standard these days) and Windows not supporting Ext4 filesystems.
Thx for reply, so i am afraid its related to Android 6 default behaviour. So if SD is formatted as internal storage you cannot access via USB from PC or managing files on it via file browser app? Thats really disappointing for me since it then switches SD card to enhanced app storage only, useless for image, videos, music etc. Of course i can format as portable SD, but then no movement of apps are possible (via root its maybe the only option).
In SD portable mode, i also had issue that SD cards randomly disconnects and one time it even needed to be reformatted. Have read about that in another thread, that this is related to physical sd mount... will see to fix this with some tape :/ (gives me not a good feeling here)

Update: checked some forums and blogs, seems not to be android 6 default behavior that you completely cannot access the files on adopted SD-card anymore. after adopting as internal storage... anyone could also reproduce this? I will try doing factory reset with SD-Card inserted..
