Even any third party software like Paragon partition manager cannot delete it's partition

You can't use a BYJU SD-card as normal SD-card. Hence trash it and buy a new one. They're not that expensive if you go for a 1Tb one

I know I can buy a new one but I just want to know why I can't format it and why I can't use it as a normal sd card

Hey! Can I Know which grade sd card you are trying to formate?

I have done it
You cannot do it with any disk partition utility (trust me i have tried them all). You have to make changes in CSD Register of your sd card.

EVO SDCard mount problem

I have an EVO and can't get my SDCard to mount. I think it is a card format issue. I was getting a lot of SDCARD damaged messages. I could get by them by rebooting. I rebooted and copied everything to my mac. On the copy it said there was a problem with the "tmp" folder. I thought I was deleting the tmp folder from my backup, but actually was the SDCARD copy. I rebooted and then unmounted the SDCARD, and tried to reformat. It gives the Format SD card, then erase everything, and then back to SD & phone storage immediately. Mount SD card does nothing. When I reboot, I get SD card safe to remove. I am running amon_RA (RA-evo-v1.7.0.2) recovery, Burnt Droid 1.0. Nothing in recovery that accesses the SDcard works. I do not have a card reader. Cannot access the SDcard from anything. I am thinking about returning to stock and taking to Sprint for them to format card. Any ideas before I do this?
Help anyone?
Try using unix tools cfdisk or fdisk to make a new partition table of the sd card, then use mkfs.vfat on it (this will erase all data, so backup the things you find neccessary if possible)

I got this to work by going back to stock. I could then access sdcard, formatted, and then rooted again. Downloaded SD card formatter for future reference.
Thank you.

Q) how to format FAT32 64gb card ? can't write/delete files.

Was wondering if anyone had any ideas on what I can possibly do??
The card came as EXFAT, but most roms only support FAT32.
I formatted the card to FAT32 which was fine .. but after copying a few files the card now refuses to write or delete files. I can still open and view media that's on it but that's about it. I can't even re-format it, it will say the disk can not be formated or write error. The card isn't corrupt though, I copied around 30gbs of video on it when it was in EXFAT partition before. J
I'm using an SD adaptor into my card reader, but yes I have ensured the lock switch is off.
edit - oh also, when you place the card into the phone it'll say that the card is damaged/blank.
Any help would be appreciated
Cheers,

Make sure you format it in the phone
Every time I place the card in, it will say the card is damaged or blank
Then it tries to format it but then goes through the same loop of saying it's damaged/blank

i had experienced the same problem i tried my best using several fomat tools. think almost all the tools in the world....failed and bought a new one.....think its better go for new card
Did you try to format it on Linux? I've experienced some problems with SD cards formated on Windows (assuming that you run Windows )

pretty much - there's nothing you can do. I decided to email Sandisk and here's their response:
I understand that the error that appear after format is “write protected”. First we would like to apologize for the inconvenience.
I understand that you are getting write protection error while accessing the flash drive. The flash drive has detected a potential fault and become “write protected” to prevent data loss. There is no method to fix this. You will need to back-up your data and replace the flash drive.
So you have to RMA it. I'm abit confused because others on XDA have successfully covnerted their 64gb cards to FAT32 without any issues.
Could it be a faulty batch of sd cards?.

So I understand you want you files and the card to work on the phone?
The phone supports FAT32 file system, if i'm not mistaken so you should format it to that.
Does a pc read the files on the card? Cause if so, then first copy them to you pc and after formatting back on the card.

Does the pc see the card and tell you it needs to be formatted or doesn't it even show on your pc?
If it doesn't even show up, you could be talking about a broken reader of your computer or a broken card.
If it shows up but you can''t acces, than it might be recoverable.

If your laptop's card reader is ok then check it form the device manager. Do you remember about setting any password to your MMC??
I've seen most of the PC doesn't show a password protected MMC.

Try testdisk (cgsecurity.org/wiki/TestDisk), maybe it can recover your partition table.

[q] sd card issues

Hi guys,
I hope this is the right section to post this issue.
Does anyone have a solution to completely erasing data from a sd card, my problem with my sd card is that i am not able to delete files from the card or add any new files. I am able to copy files from the sd card to the pc though. I have tried formating it on various computer operating systems as well as on an android system.
What i get is the format completes but after reconnecting the card to the pc or phone, all the files that were previously on the card have somehow returned and the files are not corrupt or anything because i am able to view images and play music from the sd card. Is there any method I could use or is it time to let the memory card go?
Check for Errors
Try check your SD card for errors on the computer (Mount it first).

Hi JBMorris, i have tried mounting it to the computer still no luck, I used a program called active kill disk to format it and check for errors but the program freezes on the verify and checking for errors section. I think something about the sectors not being readable so I might as well get a new sd card and thanks for the suggestion!

I think you had encrypted it with some device before.... So if you insert in that device and remove encryption...
But if you have factory reset your device and remove encryption key.. Then it will be very hard (may be impossible) to format it or change permissions

Hi killwish, that makes sense it is possible it was encrypted before as i used a different rom, so would you advice me to install the previous rom and try to format it?

Oh.. Yeah it is the solution.. If your card is in warranty
You should format your SD card through CMD
To format a memory card from command prompt, follow the below procedure:
Connect the memory card to your PC through card reader.
Click on Start > Run > Type CMD and click on OK.
Assuming the letter of the memory card drive is G.
Now enter this command.
format /q /x G: and press Enter.
Note: Don't forget to replace the letter "G" with your drive letter.

Hi Snehashish, i have tried using the cmd and get an "access denied error" even though i am using cmd with administrator rights. It seems to me there's nothing i can do as i have tried formatting using different methods.
Replacing Card
Hi guys,
Thanks for all the effort, my card doesn't have warranty and I will be replacing it, what I have learned from all this is to stay clear of encryption if you not sure of what it fully entails!
Cheers Fellas!

Of course you're right with the 4GB file limit. But for testing if your sd card still works it should be totally fine. Once the card works, you can format it to exFat in windows.

Try to use SDFormatter. Try different options. If it doesn't help, may be your beloved sd card is (physically) broken.
Fat32
I think you have to format your SD into fat32
