Info 2 Sandisk 64GB microSD card corrupt in Samsung: Error 0x80070570

So, this may be helpful with others that have had issues with Samsung, or other Android Phones and Sandisk microSD 64BG cards.

short version: if you have an issue go to and they will approve an RMA. If you want the details keep reading:

I got a 64GB microSD and tried to move the files from my PC to the card via the card reader and SDCard adapter.

I have an ATT SGSIII and a Samsung Galaxy S 4.

About half-way through I get "An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem."

Error 0x80070570: The file or directory is corrupted and unreadable.

[Description of file.mp4]

I searched high and low and found many users with this issue.

Many formatted as FAT and that worked, so, I tried that to no avail. Same error.

I tried low level format, recreating the card as FAT32, making it an active partition, 32KB, etc. Same error.

I tried formatting as exFAT in the phone and then transferring. No luck.

I tried non-windows copy utilites (Teracopy and FastCopy) that did transfer the files successfully, but when I put the card in the phone it said "Damaged SD Card"

So, I found this little nugget on Google:

"SanDisk has been made aware of potential product issues involving a very small percentage of its 32GB and 64GB SanDisk Mobile Ultra microSD cards. Under certain circumstances the cards may lock up and the card becomes inaccessible. The issue has been identified and a manufacturing fix has already been put in place. SanDisk stands behind its products and any customer who experiences this issue with the microSD cards cards is asked to contact the SanDisk support center for a resolution immediately."-SanDisk

I filled out a support request and they sent me back

Thank you. I was searching allllll over the internet for answers to quell the unfortunate realization that my card was finished. I just came off the phone with Sandisk and I will be sent a replacement card as soon as I send my defected one. Again, Thank you for this, though I most likely would have contacted Sandisk with my problem, finding this post made the process faster, helping me avoid wasting my time.
