Remove SD Partition

Hello all. I was wondering if someone could tell me how to delete a partition off of my SD card. I used Paragon Partition Manager 9 to setup a 150mb partition (which turned out to be too small) and now Im switching to a larger SD card and giving mine to someone. I loaded the card in Paragon but it doesnt give an option to delete, just resize the partition. Does someone know a way to remove it so the card will have 4gb available again? I searched but couldnt find an answer.
Try using HP USB Disk Storage Format Tool. Its what I've been using and so far it works well.
Oh I see, I googled that and it appears to be similar to the regular windows formatting. So this will delete the partition I set and restore my SD card to full space available?
yeah, if you just reformat the card as a whole it will do it, or get an ubuntu disk and use the partition manager to create a new data table and then reformat

SD card problem

So my Pantech Burst P9070 is having issues. In clockwork mod recovery (cwm) it said my SD card couldn't mount so I tried formatting it. Well apparently I must have done something wrong during the formatting process because my SD card (internal) is no longer detectable by my phone or computer. My phone shows a notification saying that my SD card is damaged and needs to be formatted but when i press the button to format it, my phone says that the SD card is removed, but I do not even have an external SD card so I am confused. Please Help!!!:crying::crying:
Don't panic. If you are trying to use your sd card for songs, apps, photos etc, then just go into windows or any other partition manager, do a FULL wipe and make sure its FAT 32. If you also want to increase your internal storage visit my thread Hope this helps.
But how am I even suppose to use the windows or any other partition manager if my SD card isn't detected by my phone or computer?
Disk Management
Look in the Disk Management Tool in Windows Vista or above.
If you don't have that or it doesn't detect it you can download a disk partitioning tool to do the job.
It none of the tools work from Windows verify that the card is unmounted in Settings and try formatting it form Android.

[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.

Damaged micro sd?

[TRANSLATED, SORRY FOR ANY ERROR
Hi everyone, I have a problem with a 16gb micro SD HC U1 Evo.
I explain it in steps:
1) I have a samsung j5 2016 (sm-j510fn) and moving continuously from the internal memory to the sd ext I almost filled the latter, so I installed the recovery twrp and the magisk root to use Link2sd / app2sd
2) I saved the files of the micro sd in a backup folder on the pc
3) I downloaded MiniTool Partition Wizard and used it (as a guide) to create a primary partition in fat32 and another in ext3, respectively 10.4GB and 4.5GB
4) I transfer some files from the backup folder of the pc to the micro sd
5) Android warns me that the sd card is damaged and the formatting process stops at 20%, after which an error message appears
I have already ordered a new micro sd, so don't comments "buy another" and the like, ty.
To recover it I REALLY tried every tool / program, followed every guide and cursed every saint.
I tried to recover it by reusing the MiniTool Partition Wizard, then an Easus program, after which I tried with the win10 disk manager, the CHKDSK / F and CHKDSK / F / R commands, the diskpart command, 2 programs for a low-level format. No way.
The problem is an image file (.jpg) with a size of 0kb, which I will call namefile for clarity. Below are the errors that I find with each procedure:
1) MiniTool Partition Wizard / Easus / win10: Unable to format
2) CHKDSK / F: namefile.jpg the first allocation unit is not valid. It will be truncated
3) Diskpart (create partition primary): usable space for this operation
Specific that, I do not know how, the files within the micro sd are all erasable but always reappear, as if the microsd does not save the changes made within it. The same happens when I delete the ext3 partition, I extend the fat32 partition and format it all.
I have also used unlocker to delete only namefile.jpg, but in any case everything returns to the initial situation. The files are readable and executable, except for the file in question.
The attempt to change the microsd via the phone's twrp recovery is also useless.
Finally I inserted the sd card into a sd adapter to remove any protection and I tried again by removing the readonly attribute via CMD, to no avail.
By now it has become a personal challenge that I now propose to you.
Further information will be provided in the comments to your answers
Good evening

[Link2SD] SD card not recognized right

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?
