preparing sd card - Samsung Galaxy S7 Edge Questions and Answers

Hi,
I'm getting "preparing sd card, checking for errors" notification whenever I insert SD card or phone gets rebooted. Notification never goes away but card is accessible and can be read or written. If I want notification to go away I have to manually unmount and remount card. I tried with several cards, even with one formatted in this device.
Anyone having similar issues?
Thanks!

Phone/SD card storage not readable after JI6 update

I received the JI6 update today, and all went well with the installation, but for some reason my vibrant can't read my sd card or the phone storage. I never rooted it or put any lag fix or any hacking like that. Everything is stock, including the sd card. When I turn it on, it says "internal storage damaged", and then the message disappears shortly after. It also says "unable to mount external sd card" with a red triangle notification. When I press mount in the phone storage settings, it does nothing.
I have rebooted the phone many times, and nothing has worked.
Any help would be greatly appreciated. This is my first post, so I am not sure if this is in the right "category". Thanks in advance.

SD Card
Mine did the same thing. I had to reformat my SD card which totally erased everything on it. (8gig) Good thing I had it backed up however I did lose some stuff. After reformating it you should be good to go.
The main problem is the internal sd card (16gb). I went to the tmobile store yesterday and all they could say was that I should try doing a factory reset. Is there any way I could get some files (pictures, etc) from the internal (16gb) sd card?

memory card not recognized

Today my x started saying the memory card was blank. It will not let me format it or anything. Anyone else have this happen yet?
I have gotten a not recognized mesage before. I took the battery out and pulled the sd card out then booted the phone. Then turn the phone back off and try re-inserting the card.
Do you have another sdcard reader that you can test it in?

I just got a Droid X used. It didn't come with a memory card. I tried the 4gb card out of my Incredible but it wasn't recognized. I tried an old 1gb card. Not recognized. I bought a new 8gb card from Sam's Club. Not recognized.
I did a search here and this post is the closest to what I am experiencing.
I tried to format the new 8gb card to FAT32 just to see what happens. No success.
I have rebooted the phone several times, removed and reinserted the card, and made sure it is seated properly.
The Settings>Storage screen states the following:
Total space - Unavailable
Available space - Unavailable
Mount SD card - Insert an SD card for mounting <grayed out>
Format SD card - Format (erase) SD card <grayed out>
Any suggestions?
If this is a software glitch and rooting is an option, I can do that. I am familiar with rooting from my Incredible. I am hesitant to root with this issue lingering.
Thanks.

Evo sd card issue

Good morning,
I recently tried to upgrade to a kingston class 4 32gb card in my evo running cm7. I have tried everything to make it work. Under storage settings, it will read the card on boot up and I can see the files in file manager. If I try to input and remount it says unsupported file system. Sometimes in the camera it says failed to access sd card. Can anyone help?

did you format the card with your phone or pc(sometimes when you do it with pc you accidentally do a quickformat, which most of the times gives problems(format fat32))
I gave reformatted in the computer and in the phone and nothing works. I can add files on the computer but after some time in the phone I can't do anything related to the sd card.i also ram as chkdsk

SD card suddenly no good??

Hey all, I'm hoping somebody can help me. I'm currently running a rooted stock S5 I have safestrap installed and towel root.
All of a sudden this morning when I open to my gallery and pressed on a picture, it would not get bigger. I didn't think anything of it so I rebooted my phone. And when it came back up there was nothing on the SD card, all of my pictures and my music has disappeared. I unmount the SD card pulled it out rebooted we mounted SD card and I got an error message saying that the SD card was blank or the files are not supported. Has anyone come across this before?
When I got home from work, I pulled the SD card out put it in a card reader and on my computer again there were no files at all on the card. I put the card back in the phone and tried to reformat it, it would not reformat. I tried with several different SD cards and I'm getting the same error message saying that the card is blank and the file is not supported.
Any help would be greatly appreciated.

you might wanna try minitool partition wizard on your pc with your micro sd in your card reader and plugged into your pc and when you pull up your sd card im sure youll see your sd card isn't fat32 anymore and is Linux so to fix youll need to right click on the sd and click delete then put back into your phone and format then youll have it working again, but sorry to say your files are now gone on your micro sd

SD card not working

Hello, I'm new here.
I'm using Moto X Style Indian version with Android Marshmallow from last 5 months. I'm using "SANDISK ULTRA microSD UHS-I CARD" with format as internal storage without any problem, but now suddenly a notification show up that "Insert your SD card", I even didn't remove my card since I put it once. I tried to insert my SD card to HTC phone, saying "Damaged SD card" with only option for format it. (I'm not able to take screenshots or click any pic)(SD card is still in my moto x style but in setting it shows "Not Inserted".)

Welcome to the world of adopted storage...
Try to power off the device, remove the card and reinsert it, then power back up. If that fails, either the card has failed or the encryption key has gotten corrupted or "lost". There isn't a lot you can do to save or resurrect it if your device doesn't see the card and unencrypt the data.
When a card is adopted as internal storage, it is encrypted and uses the ext4 filesystem, it will only work in the same device with the same key and cannot be read in any other device without formatting it back to FAT32 and wiping out all the data. There is some information here about reading the data with a Linux computer, if you have the appropriate card reader and can access the encryption key on the device.
Thanks for your reply @acejavelin,
I tried everything turn my phone off, eject card then reinsert it, still same error. Now what to do? Will I format my card with FAT32 by attach my card with PC? I know my data will not save... but I have no option.

Yes... Reformat it in a PC or in another device. Personally, I would not reuse the card, especially as adopted storage, since it can no longer be trusted.

Ok, I will also not use this card again with adopted storage. Thanks for your suggestion @acejavelin .
Seems my problem will be solved , but all my data will loss :crying:
Sounds like the problem is with your phone's SD card reader, not with the card itself. Other computers / phones will tell you the SD card is damaged/corrupted because they cannot read it (the card is encrypted), but that doesn't mean the card is actually damaged or corrupted.
You won't be able to extract your data from it unless you can get it to read the card again. I would try popping out the sim /sd card tray and shoving it back in many times, to see if eventually it will read (mine takes 2-3 tries before it will read)
If you can't get it to work you may need to contact Moto support to get a replacement under warranty (assuming you haven't unlocked the bootloader / voided the warranty)
Definitely try another card though if you have access to one, just to check and see if it will read a different card.
