music files suddenly vanish from microsd - Xiaomi Mi A2 Lite Questions & Answers

Hi there,
i'm posting on this forum section just because MI A2 LITE is my current phone, but I've had the same issue with other Android phones, too.
I use an external microSD (128 GB) to store a huge music library (about 60gb) to be played with Black Player EX. I'm pretty sure that a lot of my songs have been deleted without any reason!
Consider that the SD is pretty new and the phone is not rooted nor any other MOD.
Thank you very much

Do you find a folder named LOST.DIR in your SD card?

LOST.DIR is a system folder used to collect the corrupted data produced when the process of writing data into SD Card is interrupted such as suddenly shutting off the phone or pulling out the SD card (Wesley, 2018).

Hi everybody,
@gdivella
A few years ago I successfully used the free "TestDisk & PhotoRec" program on Windows to restore some files from my microsd card.
The program allows you to recover even overwritten files several times.
You can get more information on the wiki of the official website.

Swapping SD card

Got a brand new desire and want to put a bigger SD card in before using it in anger. Apart from unmounting the existing card from the phone do I need to do anything else before swapping? The current card has a whole bunch of folders on it - do these get recreated?
No Idea if its the right way, but I just copied the folders to my PC hard disk and then copied them back onto the new larger card. This was done via a card reader rather than the phone.
Seemed to work fine fo me.
No need mate.
I simply stuck my new card in and formatted it using the phone, the folders were created during that process
What folders are those?

I'm an Android newbie but there are a bunch of folders that look like they are used to store bookmarks, photos, music etc. There is a backup folder but ALSO the user manual and the HTC sync executable which are probably worth backing up to a PC. Plus a mystery folder called rosie_scroll??
Thanks for the advice re formatting

Anyone know if this would work after upgrading to a bigger SD after a few weeks (ie with data already stored other than the system folders). As its encrypted I get the impression there might be problems?
Can't see why it shouldn't as IIRC the encryption is based on the IMEI of the handset and that won't change.
I copied as I wanted to move the HTC pc app as well.
I will be doing it again soon as this took me from the supplied 4Gb card to an 8Gb one I had around, but will do it again (complete with apps etc) when my 16Gb one arrives in the next week or so.

[Q] I want to format my SD Card but..

Greetings everyone,
After almost a year of using xperia arc and plenty of cleanups with SEUS I never formated my SD Card. I have a 16GB class 6 one which is half full (Mostly with music, pictures and videos) and yet its full of folders from Apps i used in the past.
The question is; If i delete everything from sd card via computer, then re-mount the card will the needed folders be replaced? Also I have moved apps to sd which i still use, will the folders be replaced aswell?
and last; I already copied all the files i need to my computer, if I will re-download an app and paste the folder back there, will I have the saves back?

a bit difficult, try to delete the unused folders instead
but if you do the right backup of the needed data, yes the data will be there.
and the deleted folders created by system should be recreated

You must make sure that you format your SD card with FAT32 file system.If you are using Windows OS then there is no need to get worried.Just go ahead with the normal procedure.
Once you format,all the folders and files will be deleted and when you mount it in your phone,the necessary files and folders will be created on its own.These necessary files do not belong to the applications you moved to SD card and it means that you must create a back up of your apps before you format your card,in order to use the apps even if you format your sd card.
I would suggest "Titanium Backup" app to back-up your apps.And when you are done with the back up, make sure that you copy the folder named "TitaniumBackup" from your sd card to your PC/Notebook and then format your card.

Thanks mate, I will delete all the files from my SD Card after the ICS update that we will have in about a month, unless if i flash another rom before that so I will have a clean phone.

[Q] Weird files on external sdcard

So, I've been noticing weirdly-named, zero-byte files on my external sdcard lately. These are appearing in the root of the external card and the /Dropbox folder that contains a couple folders I sync with Dropbox via Dropsync. Most of these files appear to be named "µ". Dozens of them in each directory. Most of them show up with that same name. A few are other unprintable and weird characters.
Any thoughts?

Possible malware? I would backup both sd cards to your PC then format them. After that only put the files back in that you know you need, and the rest will be there if you need them. Remove all those odd files before doing anything though.
You could also try the sd maid app to clean it up.
Someone else posted about this a few weeks ago. I think the extsd was going bad.
The problem was on my 16gb card.
I was trying (again) to get my 32gb/class 10 working with my SGSIII. It still won't work reliably. So, I reformatted the 16gb and copied everything back. We'll see if these files return.
Thanks for the advise.

[Q] SD card issues.

I know with the introduction of kitkat or its recent iterations of 4.4.2 and so on, that there were some preventative measures taken to stop them from being written to. The question i pose is i have tried adding music to my sdcard i from my computer. The odd thing is that the sdcard will read as if it has something written to it but, in ES explorer my music folders are empty. I have looked around and nothing has been found. Other than the sdcard write fix which ARHD supposedly has according to the app i tried. The music app is use it Poweramp it will read the files but cant play them while HTC's music player will play them but only the first few seconds.
So am i stuck mainly using my sdcard mainly for pictures or is there away to get it to work pre kitkat. Also note i have tried putting the music on the onboard storage than move it to the sdcard and that was also a no-go

I'm unrooted stock rom and have copied music from pc to sd card with no problems. What folder is it you're moving the music to? I have a folder called music that I created and move any downloaded music into it. I can play it through the stock music without any problem. Possibly a corrupt folder or sd card? Have you tried removing files you want to keep, formatting then copying back your files?

I created a folder called Music same as the one on the onboard storage. It may be the sdcard not being recognized properly and files not being transferred correctly as well. The music on my desktop plays fine no skipping whatsoever. Its just once it hits the sdcard does it seem to go astray. Maybe a new rom is in order and staying away from ART.

Hi,
regarding what you said about being able to copy your music files onto the sd - are you also able to write into a file (let's say word doc)on your sd from your (presumably) windows-pc?

If you have a USB card reader, try re-formatting the card on your computer.
I've seen several folks with various quirky and random read issues, and a simple re-format cleared it up, when the phone's own format feature didn't help. Also a common symptom, the SD card works fine on other devices.
Folks keep accusing the KitKat SD permission changes. But those changes only apply to write permissions, not read permissions. My gut feeling, its some quirk with the phone itself and something to do with SD formatting.

Reformatted from the phone. can not do it from my laptop because it says it is write protected. have not got a program to get around that yet. as for creating word doc, have not tried it. going to put it in wife's S5 and see if it likes it better and see if her card likes my phone any better . as for the card itself it is a Sandisk ultra class 10 32gig.

Movies not saving on SD Card.

Hello folks, I bought my M8 3 weeks ago and it is rooted, unlocked bootloader, latest TWRP, stock sense ROM and elemental x kernel. I initially purchased a 32gb Samsung evo sd card but found myself maxing it within a few days with movies, then i bought a 64gb Samsung evo sd card and assumed all was well. I formatted the card and ran the external sd card patch app from the playstore which granted me write permission to the sd card (it is not possible on stock htc kernel but ss soon ss i flashed elementalx kernel it allowed me to write any data to the sd card).
But the problem is whenever i download a movie via utorrent and set the download path to the sd card, it downloads fine, but when i use my file explorer to check the sd card movie download folder, it shows the movie folder name but when i open the folder there is nothing inside or someimes it doesn't even show the movie folder at all, almost as if it was never even downloaded but if i switch back to utorrent, the movie is 100% downloaded and is uploading.
Sometimes, it actually downloads and i can see the movie in the folder, but when i click on the movir, it says 'Sorry unable to play thid file'. I have use astro file manager and es file manager, i have used diceplayer, mx player sand bs player. I don't think the file manager or the the media player is the problem. When i open settings and go to make more space, 10gb of my sd storage is being taken by these files but they are nowhere to be found on my sd card storage using a file manager. But i know these movies are on the sd card because it is taking up gigabytes of space.
I've tried to reformat the sd card, factory reset the phone e.t.c. but i am still having the ssme issue. Any help would be greatly appreciated, thanks.
Can any other apps write to the card? I'd also get myself a copy of root explorer. Have you tried searching for the files in question. They may not be in the folder you think they are.
Also the stock kernel does support sd card write access with patch. Might have to be s-off though.
What formats are the movies in? Try to copy a movie with a format you know works in and then do one with another format and check. I know certain formats don't work with HTC.
I'd also try and see if other movie watching apps can read it. If you don't mine me asking, when you formatted the card what did you format it too?

Some are in mp4 and some are in matroska (mkv). I have already tried that and it didn't work before. I have tried diceplayer, bs player, mxplayer and the default htc player. The card was formatted on my htc one m8.

Yes, i know the stock kernel does not support it. Which was why i wrote in the op that i flashed elemental x before performing a successful write access patch.
Other apps can write to the card, i played the respawnables from the sd card, i can copy pictures and my nandroid backup. It's just my movies that sometimes copies into a folder which is empty inside or it full copies and then when i try to play, it shows me a sorry cannot play video file error on all the movie players i have tried from the playstore.

Have you noticed one working more then the other? or do they both not show up. My suggestion is your reformat the sdcard on your computer instead of through your phone to be fully compatible with the movie files. I have an external 64gb and I have no issues. I formatted it through the computer though.
Also, try to restart your phone and check for the files, or using a different file explorer.
Nope. You didn't read my reply properly. The stock kernel DOES support sd card write access with patch.

I understand that, but a 32gb sdcard is quite different then 64gb sdcard with the way its formatted and that's what I am worried about.
I'm using a samsung 64gb evo card no problems. Why not try a different torrent app. I prefer the kickass torrents app as it has more options and allows you to open the download folder direct from the app.

That is exactly what i'm using. A samsung evo 64gb. I will attempt to reformat it on a pc tomorrow.
I tried to grant write permission on the stock htc kernel but it didn't work with the 2 apps i found on the playstore. But it worked instantly with elemental x kernel.
Shall i reformat it on the pc with the memory card still inside the phone?
I'm guessing it's due to the file sizes. When the card is formatted as fat32 it has its file size limits.
Check some more on that note to get some specific info. Just a hunch

I wouldn't recommend doing that no, if possible take it out of your phone and use an adapter to connect it to your computer. You want a direct connection to the sdcard.

Yeah you don't want to format to FAT32 thats for 32gb cards and below. For a 64gb you want to format it to exFAT. Thats how mine is formatted, and how it should come honestly. After that you shouldn't have any issues reading and running your movie files. According to this article video files over 4gb cannot be accessed which would be your issue with the files on a FAT32.
http://forums.androidcentral.com/ht...nnot-handle-video-files-greater-than-4gb.html
so that could be your issue as well.

I have come across that thread before making this thread. The SD Card was initially in exFAT format but when the issues arose I formatted it to FAT32 and now I have reformated it using windows to exFAT. I'm copying the movie files now and will see what happens.
My movies are all 1080p but below 2gb file size, I have copied the movies to my limited internal storage and they work perfectly file. It is simply when I copy them to the SD Card that they become lost within the LOST.DIR or they copy and i get the Sorry cannont play video file error with any media player I download from the playstore.

This issue seems strange to me. I also have a 64gb card, formatted to fat32. I have no problems at all moving uTorrented movies from my downloads folder to extSD (I have a movie folder on ext, but I download to internal). Maybe try ES File Explorer to move them. That's what I'm using.

Last night i fornatted to exFAT on windows using my sd card adapter, then i mounted it and downloaded 5 torrent movies directly to the sd card. I woke up this morning and discovered that the folder where those torrent movies were downloaded was empty. But somehow the movies are on the sd card and taking up space, but i iust can't find them.
When i download the torrent movies to the internal memory, it is fine, when i copy the torented file from internal to sd card, it is also fine. But it just seems impossible to download torrents directly to the sd card and bypass the copy from internal to external always procedure.
I will try FAT32 format on windows and download torrenrs directly to the sd card, i am hoping this will work as i am very tired of this issue. I invested a lot of money on this phone and this 64b samsung evo and i am so far not impressed.
Also in the op, i mentioned that i have tried astro and es file manager. But thanks.
