Help with Unerasable SD Card

Hi. I've checked the SD card for physical errors and it's all good, have partitioned and erased on OS X, both in Yosemite and the most stable by far Snow Leopard, Linux (Gparted, the most popular one) and Windows with both it's built-in and third party partitioners but when I partition or erase, giving it the title Untitled (or any title), it would partition or erase successfully with that name but when I click or check it again, it's back to the previous name and the contents are all still intact, as if nothing happend even the programs like Disk Utility and many utilities used says it's successful. I've tried it on a USB reader in case there's a problem with the physical SD card slot itself but the result is still the same. I've also checked the SD card itself if the tab is in protected mode, it's not.

It started when I tried to create a USB installer for Yosemite using the createinstallmedia built-in in its .dmg installer using OS X's terminal. How can this be erased and partitioned?

Thank you in advance. Belated happy father's day.
