[Lenovo A850] SD CARD PROBLEM - Lenovo A850

Okay so it is been some months that I am using this phone, there is actually no problem with the SD Cards that I have used in the past few months, I bought this new SD Card(that has problem) in the last 1.5 month/s it worked really well and no problem at all. But in the last 2 days, I restarted my phone(changing sim card) turned it back on, then it did not detect the SD Card, I have tried some things like formatting the phone but it did not fix it, I have tried inserting the SD Card into a card reader and insert in my computer it worked, it detected the SD Card, I then tried formatting it from the operating systems formatting tool, I also tried formatting it with SDFormatter V4.0 but it did not fix it. There was a day when my friend tried to edit voldf.stab file from /etc/ since I want it to be like the External Storage will be Internal and vice versa. That is all the informations I can give and is in my mind right now, you can ask more questions regarding this tho thank you so much for reading and I really need help in here. I cannot figure it out.​

My assumptions-
-Faulty SD cage (in case you accidentally slotting in SD card with force)
-Recent change in kernel (I really don't know about kernels, check the other thread)
-Pathogens....( I mean viruses, probably system level that bugs the interference from SD slot to system)
That's my guess. You may try to consult an experienced phone serviceman, or Lenovo Service Center (if your city have one).

[Q] Damaged SD Card Help

I have a Samsung Galaxy Showcase I500 i was on stock 2.3.5 and i decided to flash a custom rom so i installed newest miui rom for I500 1.12.9 i think.. So my problem is that if i reboot my phone it seems to make the sd card corrupt. which isnt really a problem because i always keep it on. The first time it happened though my phone rebooted on its own and was kind of glitchy. Since then i have had the sd card damaged problem 2 more times but when i rebooted once and once when i pushed files from my computer to my sd card in usb storage mode. i really like this rom but i cant continue to reformat my sd card every couple of days and reload music download album cover redownload themes etc...its getting old... any help would be greatly appreciated. by the way i have tried reformatting with my computer and my phone so i know that wont fix it.

Does the computer recognize the SD card?
On computer format the sd card
Sent from my GT-I9000 using xda premium
Reformat
Reformat your SD card by right clicking -> properties -> and format it. See if this helps. Also, try using another SD card to see if it is just your SD card or your phone that is bad. Deduce and solve
i have tried all of this reformatting from my phone from my computer every which way i could. i have used my disk management and nothing works. i decided to keep my 8 gb in there it is working without flaw. but both the 16 gb ones just keep getting corrupted. This is weird because when i tried installing miui with my 16 gb sd card it wouldnt work so after pulling my hair out for two days i found a post where someone said to use an 8 gb card to install it and i did and it worked perfectly. i guess this phone rom doesnt like 16 gb sd cards.

Q) how to format FAT32 64gb card ? can't write/delete files.

Was wondering if anyone had any ideas on what I can possibly do??
The card came as EXFAT, but most roms only support FAT32.
I formatted the card to FAT32 which was fine .. but after copying a few files the card now refuses to write or delete files. I can still open and view media that's on it but that's about it. I can't even re-format it, it will say the disk can not be formated or write error. The card isn't corrupt though, I copied around 30gbs of video on it when it was in EXFAT partition before. J
I'm using an SD adaptor into my card reader, but yes I have ensured the lock switch is off.
edit - oh also, when you place the card into the phone it'll say that the card is damaged/blank.
Any help would be appreciated
Cheers,

Make sure you format it in the phone
Every time I place the card in, it will say the card is damaged or blank
Then it tries to format it but then goes through the same loop of saying it's damaged/blank

alright i'll give it a go soon

i had experienced the same problem i tried my best using several fomat tools. think almost all the tools in the world....failed and bought a new one.....think its better go for new card
Did you try to format it on Linux? I've experienced some problems with SD cards formated on Windows (assuming that you run Windows )

pretty much - there's nothing you can do. I decided to email Sandisk and here's their response:
I understand that the error that appear after format is “write protected”. First we would like to apologize for the inconvenience.
I understand that you are getting write protection error while accessing the flash drive. The flash drive has detected a potential fault and become “write protected” to prevent data loss. There is no method to fix this. You will need to back-up your data and replace the flash drive.
So you have to RMA it. I'm abit confused because others on XDA have successfully covnerted their 64gb cards to FAT32 without any issues.
Could it be a faulty batch of sd cards?.

Can't mount SD Card in CWM - Searched already!

Hey guys, I need help.
After countless hours of stressing over my SD Card, I still can't get it to mount. I even went downtown to get a new one. I have a Motorola XOOM.
Problem is, I can't even get adb to work cause I can't access usb debug, because I wiped data hoping to re-install the rom. Now I'm still in CWM with nothing to do.
What could it be that's causing my SD Card's to not mount? There was one SD Card that mounted but that's not here right now. Would it be the SD Cards? I reformatted them to FAT32 as well.
Go here see if you can find some solution, search.... the search is a powerful tool, thank you sir.

It happens some time
I have two sd cards
One of them shows in recovery mode other is not mounting though both works great in device for other stuff..
I think its due to lack of some files on them after i use the second card for one week in my device for now they both mounts in recovery.
So what you have to do is use your card in some other android phone for some time..
Installed one or two app on it etc.
Then try again
we all should be polite enough to press thanks for anyone who helped US.

Following today's system upgrade my SD card won't mount

I've had my Idol 3 for a couple of weeks now and I just love it . . . so do my 'green' friends! However . . .
My Idol 3 got a major upgrade today, and now the phone won't permit mounting of the SD card . . . home of many apps!
The option under Settings/Storage is not greyed out, it's just that when I tap 'Mount SD card' nothing happens. I'm also getting a continuous notice, i.e. "SD card safe to remove".
The card was not removed either before or after the upgrade, but since I have had the above problem I have done reboots, restarts and hard reboots, and and have removed and replaced the card a couple of times . . . . I'm at a loss on this one!
Does anyone have any suggestions that will help me get the SD card mounted please?
Many thanks!
Just maybe a very strange coincidence here. I have been using the same 32gb sd card since I bought this phone and never had a single issue with the card or the phone (related to the sd card). This morning I checked to see if there was an update, I did not download or install it (since I'm rooted) but man ever since that moment I have been having f-ed up sd card issues. The same types of problems with it randomly unmounting the card and telling me the card is safe to remove, finding the card unmounted and touching the Mount button does nothing and just now I removed the card and my Chromebook is asking if I want to format it... WTF?
All this makes me wonder if Alcatel secretly installed some updates in the background today even though I did not intend for a system update. Hmmm.
I had similar issues with a sandisk microsd.....with it randomly losing everything on the sd....I switched to a samsung microsd and the issue went away so I think it's just very picky with the cards and you should try different manufacturers...also fat32 seemed more reliable than exfat. Samsung and Adata are two I had good results with outside sandisk which I previously considered the gold standard.
Thanks folks.
At this time I don't think it's an SD card issue unless the update corrupted it.
I mean, it was fine before the upgrade guvnor!

Backup the data to pc...format the card in the phone...copy the data back.
Same happened to me on the first OTA update and on this OTA update. I took my SD card out, put in a computer, copied all my files to a desktop folder, re-formatted the SD card, moved all my files from the desktop back on to the SD card once the format was complete and the phone mounted the card no problem. Total PITA and will consume about an hour and a half of your time to do all this. Not sure why this keeps happening on OTA updates, but next time, if Alcatel releases another OTA update, move all your apps back to the phone and remove your SD card prior to initiating an update. Only think I can think of?
Thanks both. Formatting is apparently the only way to go except that my computer wouldn't read the card via the phone.
Soooooo, I have mounted the micro SD in an adapter, and the card is currently being copied to my computer.
I'll let you know how that goes after I've done the format and copied things back.
Maybe just removing the SD card prior to an upgrade will prevent corruptions, or do you think that the upgrade 'needs' the SD card in place?

As the external sd is considered "optional" there is no reason you can't pull it prior to doing an upgrade to eliminate the chance of it getting corrupted.
If you have TWRP flashed and your situation is like mine was you'd find IT could read the card just fine and adb access while in TWRP copied off the data for me so seems related to the actual rom.
The solution
As some of you may have expected, and suggested, I was able to resolve my issue by . . .
1 Backing up the data on the SD card
2 Formatting the SD card
3 Copying my data back to the SD card
However, the .android_secure folder on the SD card was 'locked' by the phone, so I removed it and using Windows Explorer I copied the contents - all my apps that had been moved to the SD card - manually.
If you go this route yourself, your 'favorites' that you dragged to the home screen will be missing, so you'll have to re-do that process. It only takes a matter of minutes.
I want to thank those of you who responded with suggestions that pushed me all the way to the top of my 'success' mountain. The view is great!
Now if only the upgrade hadn't corrupted my SD card in the first place. Grrrrrr!
However, for those that don't realize it, the Idol 3 is a terrific phone that is soon to increase in popularity and recognition.

You might consider installing syncthing and running it on the pc and phone...it uses p2p technology to sync folders between devices....open source version of bittorrent sync. Glad you are back up and running.

corrupted sd card but PC sees it just fine

So, about the problem. All was fine untill a few hours ago. My note 10 notified me that my SD card is corrupted. OK, no biggie, lets just take it out and put it back in. Worked before, but not today.
Tried the same SD card in my laptop, worked without any problem. I'm feeling trolled. Next i tried with otg sd card adapter. It says "no supported partition was found".
Next, tried another SD card, still nothing. Tried that one with otg - bam, works. So, it's not card that's bad. Tried another one, was empty so i formatted it on phone. Nope - still corrupted. No matter how many times i formatted it, it's always corrupted.
But it works on laptop. All 3 of them work on laptop. Two of them i can see with otg, the one that was all the time in the phone says no supported partition.
Then i thought, maybe the sd reader in phone broke. Rebooted to recovery and guess what? First SD card that showed corrupted message works just fine in recovery. Now, one reset to factory setting would probably solve the problem but i have tons of apps that i'd need to backup and no space to do it because my sd card ain't showing in OS.
All i wanna know is am i doomed to reseting android or is there any trick i could use to avoid that?
Copy all things on your pc,format the SD Card in the Phone and copy all Things back to SD Card
nope, didn't work. had to reflash OS
