Bought a GT6800 and a 32 gb microSD UHS card from A-Data. Two days after something happened to the card while the tab was indexing dictionaries on it. Now card is recognized by a Windows PC, but won't open with the message that is has to be formatted, and won't format with the message "Windows was unable to format..".
I did read this thread and many other similar, and here is what I tried so far:
- Formatting via Windows Explorer
- Formatting via Windows Disk Management
- Formatting with MiniTool Partition Wizard
- Surface check with MiniTool Partition Wizard (no error)
- Wiping partition with MiniTool Partition Wizard
- Low level formatting with HSS LLF Low Level Format Tool
- dd if=/dev/zero bs=1M count=1000 of=/dev/sdb
- partitioning with fdisk in linux
Is there anything left for me to try?
One more thing: not sure what capacity the card had before the incident, but now fdisk reports it to be 32.4gb. A bit too much for a 32gb card, don't you think?

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 everyone,
I just bought a 32GB sdhc card. At first it mounted just fine on my windows 7x64 machine. I opened up minitool partition wizard home edition to format the card with about 2GB for sd-ext and the rest for fat32. It said it was successful but now the card will not mount in windows 7 or in my optimus V phone (which supports 32gb sdhc).
So then I tried to format the card with CWM instead directly on the phone. Here is the log from that experience:
Partitioning SD Card... please wait...
checking script requirements...done
unmounting all partitions...done
partition 1 may not be aligned to cylinder boundaries.
to continue, this must be corrected.
this action will remove all data from your sdcard.
correcting cylinder boundaries...sh: 0: unknown operand
done
err: must have a fat32 partition greater than 0MB
Done!

Basically I think minitool screwed up my card (or i did using the wrong settings) or the card was already bricked; but not so much that my card cannot try to read it. However, I can't mount the card in my phone in CWM or if the phone had the rom loaded. Further, I can't see it when invoking fdisk -l through ADB.
Does anyone know if there is a way to somehow fix this cylinder issue or do you think this card is bricked and is not even heavy enough to be a paper weight?
thanks.
it looks like CWM uses sdparted to do these operations.
I tried running that through adb manually but it failed with the same error:
err: must have a fat32 partition greater than 0MB

I've can't find the answer anywhere, so I'm starting a new thread.
I have a problem partitioning my 32 GB class 10 micro sd card. I need to partition it to use link2sd, so I need other partition to be ext 2/3/4. So if I try partitioning it with minitool, the first partition (fat32) works fine, but the second one (ext) after partitioning shows type as "other" and that the partition is full (no free space). If I partition it with cwm recovery, minitool shows what should be ext partition as unallocated space.
AOMEI partition assistant can't finish partitioning to ext (fat32 can with no problem), and gives this message:
Sorry, the current operation has been canceled!
Information Code: 305
Description: Unknown Error.
I haven't been able to find not only solution, but even similar problem is nowhere to be found, so I hope someone can help.
Hi,
My SD card suddenly went unmountable. My phone restarted automatically and hasn't been able to mount the card. It is not recognizable in Windows too. I just see a grayed out drive that has 0MB.
I'm using Apps2SD on my phone and I had to partition my SD card with one Ext4 partition and on FAT32.
The thing is that because the first partition is Ext4, Windows cannot see the second FAT32 partition.
How can I check if my SD card really went dead or is it a matter of corrupted file system?
What program can I use to scan and check Linux partitions on SD card?
[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.

Good evening
