Are there any apps for android for syncing files that are in the phone or sd card, to external usb or a file in the sd card?
I have got 32gb Lexar C.10 micro sd and in the 5 months of using note 2, phone corrupted sd card and i am tired of rescuing files and then copying them to formatted sd card.
I want to backup files on the go (i wish there are any incrementally backing up app), so that i can restore them back when faced with any future corruption of sd card.
I think note 2 or JB has some issues with the filesystem of micro sd's.
Any help? Thanks.
I have a PNY 128 GB SD Card formatted as external in Marshmallow--in an HTC One M8.
I have a directory of music on a PC. Recently the size of this directory exceeded 59GB (64GB).
I keep the SD Card on my phone synced to this directory with SMBSync or FolderSync ---top rated apps.
As soon as the PC directory got bigger than 64 GB, files transferred to the SD Card in the phone were corrupted. My music player Power Amp said "Failed to Play File"
-------------------------------
1. I verified that the files were corrupted by comparing MD5 checksums on the SD Card files versus the same files on the PC.
2. The SD Card is PNY 128GB. Windows can fill it up, so its not a counterfeit card.
3. Card was formatted in Android as external, then ejected put in SD Card Reader-- Windows checked all sectors, no problem.
4. Tried to Sync with two different top rated apps via SMB protocol/wifi...files are corrupted.
Has anyone seen this?
I have an non rooted, official Tab Pro 12.2 on 5.1.1. with an 64Gb sandisk Ultra SDXC micro usb card. I use the sd for movies on holidays. A few weeks ago i suddenly couldn't delete or write any files anymore. Not even format the card in the Tab, on Windows Xp, Windows 10, or even Linux Mint. In other tablets or phones i get the message that the card is empty, but can't be formatted. When i take a picture, the image is stored on the sd, so it isn't broken. I just can't remove it anymore.
I tried several programs for formatting sd cards, but i get the message that the card is write protected.
There is an folder named .android_secure and it can't be removed. I googled and found out that this is folder is created by app2sd, but i never used this app. Also i never moved apps to the sd card, so i don't understand how this folder is created. By the way, the date of the folder is 1-1-1970. Very strange.
It's very easy to buy a new sd card, but what if this happens again and ruin my next sd?
Has anyone had this problem and perhaps has a solution.

When the sdcard goes read-only the card detected a major fault with the card and a protection mechanism will switch the card to read-only mode so you can get data off (hopefully), unfortunately the card is toast there is no way to revert the read-only/write protect mode, Sandisk has lifetime / 10 year warranty on most sdcards so just contact their support and they will ask for the serial number on the back of the card (use a camera or magnifier glass to read it), do the rma form and send it to them and they will send back a better brand new card usually a good model, if you have valuable data on the card you can snap the card in-half (since it is read-only you can't erase it), just make sure to note it with support ..
I have been through two sandisk cards (both 64gb), one went poof dead, then the other did what yours is doing can't delete/write/format but you can see all the files - sandisk replaced the card twice no issues, the last card they send it working great no issues.

Thanks for your advice!
I mailed Sandisk and they will sent me a new micro sd card. They know about the problem with some of there micro sd cards, so there was no problem with that at all.
Worth a try.?
This has happened to me several times on different occasions.... typically after I have deleted all the extra and hidden files and folders my phone apparently likes putting on my SD cards. When I get that message, I will right click C: drive, select properties, go to Hardware tab, highlight the storage device, then run the disk check on the tools tab. 9 out of 10 times it will scan and fix errors on the disk... when it does not.. I redo the whole process.. . lather... rinse... repeat

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
I just bought a new sandisk sd card 16gb, but everytime i put files in it, the files keeps corrupting. For example i put a song into the sd card, then after about a minute the songs cant be played again.... and when i copy some game files (data, obb, etc) from my pc, the files can be seen on pc but not on android, and when i restart the android, the files are gone and my sd card is empty again...... how to fix it?
P.S. i tries SD Tools speed test and this is the result
