[Q] SDcard not recognized [SOLVED]

Hi this is my second time coming across this problem, and I'm posting after searching/ googling for an answer. Any help is appreciated.
-I took my factory 16bg micro sd card out of my phone and put it into an SD card adapter which i then placed in my computer.
-using W7 and easus partition master i formatted the card to fat32
-when placed in my phone, the card is not recognized under settings or in cwm
-The card is fully working under linux and windows.
-I rewrote my backup of my sdcard to the newly formatted card thinking the addition of androidsecure would fix the problem. It didnt.
-I reformatted with windows a few times with no avail.
Again, any help would be appreciated as I am at a lost and would not like to have to start over with odin.

EDIT: Problem solved with Panasonics SD card formatting utility. It did a quick format that took all of 3 seconds. Popped it in my phone and it worked.
-I hate opening and immediately closing a thread, so my apologies.

Try reformatting through your phone.
Settings > SD card and phone storage > unmount SD card > format SD card

When I go to that tab under settings, mount sd and format sd are grayed out. It says to insert an sd card. Any thoughts?

Try formatting to fat, not fat32. I think your phone will recognize it afterward and then you can use the phone format tool.

I know that this thread is marked solved, but I had a similar problem that this solution didn't clear up. I re-formatted the sdcard in the phone but, when I boot into recovery, CWM still can't mount it ("Error mounting /sdcard"). This means I can't make a backup, which is going to be a prerequisite for trying out a new rom.
Any suggestions?
Thanks.

same issue...
I am having the same issue. I have CWM up but it will not mount the SD card, can't seam to find any real straight forward answer. Any help would be vary helpful.

SD card bad disc?

Hello, I when I tried to partition my sd card using MiniTool Partition Wisard to create two partition (20GB with filesystem ext2 and 10 GB with FAT32) it shows me that the partition process was successful. However, I could not see the SD card on my computer (it should show the partition with filesystem FAT32). Okay, therefore, I decided to remove the card from the computer. And when I inserted it back to the PC, it still can't show the card. Therefore, I decided to open the MiniTool Partition Wisard to see what happened. And it says that my SD card has Bad Disk filesystem. Also, when I insert the card into the phone, its says that my SD card is blank. What when wrong? Isn't the partition successful? What can I do?

[Q] My Memory Cards Space Got Drastically Decreased.

I have been using a 4gb memory card out of which 3.6 was usable. One day, I connected it to my chromebook and transferred a few files and directly pulled the wire off forgetting about ejecting the device and turning the usb mass storage off. Then I opened the file manager it was showing total storage:447MB and availabel storage:447MB. pls help me with this problem.

Here you go
First point first - Backup your data
I assume that you have access to a Windows or a Linux desktop...
For Windows you will need Minitool Partition Wizard Free Version...
For Linux - GParted will do the job...
----------------------------------------------------------
For your specific problem, it appears to me that the primary partition of your SD card is accidentally shrunk...
So, Plug in your SD card
Open up Minitool Partition Wizard or GParted, find your SD card.....
... and if I am right, you can see 2 or more partition in your SD card
[Make sure you have backed up your data before proceeding]
1. Delete all of the partitions present in your SD card one by one (right click on the partition to find 'delete')
2. You will now end up with an unallocated space of size of your SD card.
3. Right click on that unallocated partition and Create
4. Make sure your new partition is Primary, NOT LOGICAL, and FileSystem = FAT32
5. Apply your changes, and your SD card will be showing it's full capacity.

Thank you I will try it out and let you know if it works

One reason may be that your sd card has some bad sectors due to which some part of the sd card may not be accessible or maybe there is some kind of virus in your sd card. Actually it happened with me also but in my case it was my pen drive and the reason was some of the sectors were not working properly and at last pen drive did'nt work at all....

If that is the reason wouldn't formatting the sd card work out.

Recovering an "Adopted" SD Card?

Hi folks,
I have an SD card here that I was using for Adopted Storage but I've managed to get it stuck as an "adopted" card and can't seem to get it back functioning as a normal SD card
Long story short... I wiped the device the card was in but I didn't "unadopt" the SD card before hand - as in set it back to portable mode. While the device could recognise there was an SD card afterwards, it couldn't prepare it for use and suggested a card error or something to that effect.
I figured I'd just pop it in my laptop (Windows 10 x64) and re-format it but this didn't work. Failing this, I decided I'd "nuke" it using Minitools Partition Wizard. While this program had better luck identifying the card, could display and delete the partitions on it and could run the Wipe task - it had no effect on the card... the partitions just re-appear after any attempt to nuke them!
Has anyone any ideas about how I can restore this card back to a normal FAT formated SD card?
Just to clarify - I don't care for the data that might be on it... I just want the card back usable
Thanks

Recovering an "Adopted" SD Card?
The best solution for now would be to plug the sd card into a phone with android 6.0 so that the phone can read the card and then while setting it up,you can format the card as "normal "(the part where it asks you whether to use the card as in adaptive storage or for accessing files).

When I try this, I get "Unsupported SanDisk SD card"
I'm then asked to select either Portable or Internal and then Erase & Format but neither work. They fail at 20% and the message "Unsupported SanDisk SD card" is shown again
I'm a bit stumped. I thought surely the encryption used on adopted cards was only to stop external reads. It seems in this case it's stopping me from writing to or formating the card

problem formatting SD card

Hi All,
I have a problem with my SD card. (Sandisk 32gb).
The SD card was used in an android phone and formatted as internal storage, which I'm guessing encrypts the data as well.
In order to use another card in the phone, the card was removed and 'forgotten' in the phone (yeah... not very smart...)
I have already come to terms with the fact that my data is now lost forever, since the key for the encrypted data was deleted. I'm trying to reformat the card so I can use it again.
The problem: I can't format the SD card.
I've tried the following solutions, which did not work:
- Try to format the SD card using the phone. -> this gives an error message.
- Try to format the SD card using a computer:
The card doesn't show up in explorer, so I worked around using EaseUS partition master, when I try to wipe the disk, or when I try to delete partitions, I get an error. When I do a surface check, the program crashes.
- Try to clear the SD card using DiskPart, which gives a 'Data Error (cyclic redundancy check)' error.
What else could I try?

If you format your SD card directly from a PC, your choices are NTFS (which an Android device can't read) or FAT32 (inefficient & doesn't support files greater than 4G).
The best way to format an SD card is using the official SD Card Formatter from the SD Association:
https://www.sdcard.org/downloads/formatter_4/
This will format the card as exFAT which is supported by Android, while maximizing storage space.. Download, install, format, enjoy!

Thank you EEngineer for reacting so quickly!
I've tried the SD card formatter you recommended. However, although the card is recognised by my computer, it is not assigned a drive letter for some reason (I've tried to give it one using disk management, without success (it basically gives a cyclic redundancy check error every time I try to do anything with it)) and it doesn't show up in explorer. It follows that my card is not recognised by the formatting program, and so I can't get it to work.
My hypothesis is that the phone has formatted the card so that it cannot be read by my computer anymore and then threw away the key, so that it cannot be read by anything anymore. (which really sucks, because there's probably nothing wrong with the hardware of the card, and yet I'm going to have to throw it away if I can't get it to work)
Any other ideas?

Have you tried fdisk command?

There has been some time in between posts. Sorry for that. I really appreciate you helping me out.
I'm quite keen to get this issue resolved, since if I don't I've just wasted some money...

Yes, I have already tried fdisk. It resulted in the same error described above.

Try SD formatter for Windows, it has some tools to diagnose/repair SD cards.
