Hi all,

So my SD card recently kept unmounting itself from my phone, and I've been allowed to get a full refund as it's a known compatibility issue with SanDisk cards and S4.

The problem here is that I cannot format my card using most means (through PC, MAC, Phone, and DSLR). The card is currently using exFAT. It mounts to my system fine, I can see all files stored perfectly, although whenever I delete the files individually and remount my SD card, all the files appear again!!

Through PC, I have used Disk Management, EaseUS Partition Manager.
Through MAC, I've used Disk Utility, SD Card Formatter v3.

At the moment, i don't feel comfortable in sending it back, with personal data easily accessible.

Anyone have any other methods / ideas?

Sandisk messed up and make faulty card. It seem this only happened to 64gb SDXC card. I already had mine replaced under warranty 1 time and then after a while it's acting up again. So I ditch that card and buy the other brand.
