I bought a Sandisk 64gb MicroSD, which came formatted in exFat. I could see this partition in both Windows 8 and Linux on my laptop, using an SD card adapter (plugged into the SD card slot).
I wanted to reformat it to FAT so that I could use it in my Cowon mp3 player and/or old phones, so I booted into Linux Mint and ran Gparted. I formatted to FAT leaving 32mb front and back (which I read was necessary to make sure Windows sees it), and in Linux all was well. I copied some files over, put it in the Cowon and it worked.
But... it no longer shows up in Windows. Neither while it's in the device (over USB), or when I put it directly in the laptop in the SD card slot.
I have tried using Gparted to re-partition the drive and reformat using a number of different options - including having no partition, a small FAT or NTFS partition etc, and nothing works. In Windows, not only does it not show up as a partition, but it can't even see it as a drive - Disk Manager doesn't show it, and neither does EaseUS.
I have also had the same problem with another MicroSD card, using the same steps - works in Linux and on the the device - Windows no longer thinks it exists.
Help much appreciated!

I assume you mean FAT32? I'm not sure what gparted calls them but FAT16 certainly won't work. Also, you should be able to use the entire 64gb. It sounds odd to me that you'd need 32mb before and after. Try using the entire card first and see if that helps.
If not... I'm not 100% sure but even if there was no partition info on the card then Windows should still display it in disk manager. Try using the same card reader that works with Linux on the Windows machine. I'm thinking the reader might be faulty.

I bought a new 8gb sd card, formatted in two partitions, worked perfectly until I fiddled with paragon partition to revert my card to normal. Now it can't format. Size unknown. Please insert sd card. Some of the errors. Paragon manager says unallocated space. Can't format from there. Any suggestions. Though now I have a 32 gb but I don't want to waste money so anybody can help.
Stick the memory card into a camera and format it.
$ sudo fdisk /dev/sd* (* being your sd card)
delete the partitions. I've saved a many flash devices using the Linux fdisk command.
Anything i can do with vista 64 bit
anything i can do on vista 64 bit.
Try using HP USB Disk Storage Format Tool. I use it to get my card back to normal after playing with paragon, hope it works for you.
Go to sourceforge and download the live cd for gParted. That'll get the little bugger spark'n again.
Fixed
I fixed it using vista inbuilt partition manager. really simple easy and effective. no bugs. everthing went smoooth.
Hi Guys,
Can I get help on how to copy a file larger than 4GB to SD card? I tried to read up and try a lot of stuff but still really lost here. I'm on Virtuous rom.
- I tried to format my card in ext4 but the phone don't recognized it. (I read stock rom don't support ex4)
- I tried to format the card in the device but it didn't work. (I think the phone format the card to FAT32 but not sure as windows just say "generic hierarchical" file system).
- I tried to format the card in NTFS and the phone didn't recognized it.
- Tried to format the card in FAT32 and can't copy the 5gb file because of the 4GB limitation.
- I tried to format my card in exfat but phone don't recognized ( I read that stock kernal don't support exfat).
I think you can only have your card formatted as FAT32 for the phone to recognize it. 4GB is a limitation of FAT32. So that's it, you're stuck with that limit.

It sucks when alot of devices depend on fat32.

Hey everyone! I have problems with multiple micro sd cards.
I have an 8gb micro-sd card that will not read anywhere at all. The computer won't even recognize it as a device. My phone will say that it is unsupported, and cameras do not recognize it.
I also have a 64gb micro-sd card. The problem with this one is that it is recognized, but not able to be formatted. my phone and computer can not format it. And a camera says that it is too full to take pictures, but that there is not a single file on it.
Any ideas on what to do about any of this? Any help? or just any useful thoughts?
You may want to try the HP USB Disk Storage Format Tool.
With it I've been able to delete partitions that I messed up in linux.
If that still doesn't work you could try a linux livecd with gparted on it.
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.
Hello,
I have a problem with Link2SD which I hope someone knows an answer for. My setup looks like this:
Hardware
Galaxy A3 (2017) - SM-A320FL
SanDisk Ultra MicroSD (64 GB)
Software:
Android 8.0.0 (A320FLXXS3CRK1)
Newest TWRP for my phone
Newest Magisk
Universal Init.d Injector v2.2 (https://forum.xda-developers.com/android/software-hacking/mod-universal-init-d-injector-wip-t3692105)
How I setup the partitions of the microSD
First Partition as FAT32 (Primary) with a drive letter assigned. Second Partition ext4 (also Primary) without a drive letter. MiniTool Partition Wizard was used for this process.
Also tried a few variations of the above like making the second partition ext2 or setting the first partition to active but in the end it all made no difference
Now the strange part ....
The partitions are properly detected when I connect the microSD to the PC using a card reader.
The first partition is also detected as external memory by android and I can use it like every other SD with one partition
Link2SD is also able to detect the second partition, mount it at start and link apps to it
The problem is that my PC wont detect the sd card when I connect the phone to it. When I reformat the SD back to one partition the SD card is detected without a problem (explorer showing the internal memory aswell the external memory)
[*]Sometimes the card is also shown as not detected in the default samsung file explorer even tho the apps moved to the sdCard are stil working
Does anyone have a clue what is happening here or what I am doing wrong?
Dear user
I am having the same troubles with my a320fl when attempting to use 64gb sd card partitioned with fat32 and ext2/ex4.
Once I enter the card in the phone and restart it doesn't register on the phone.
I hope someone else can help us!
I have the same problem, also with a 64GB Samsung Evo, could this be an A3 issue?
