Motherboard: Asus p8z680deluxe
Flash: Sandisk Extreme 64GB USB 3.0
Got 4 USB 3.0 ports. on back(intel) and in front (asus fron panel).
A few days ago was no longer found in the usb 2.0 ports, i try inserted into different PC.
Led light is on, but no other life in Win7
Only recognized in front ASUS panel.
When i insert it on the back of MB in USB 3.0 (intel) she not works.
I try format in different formats. I do full fragmentation in different programs. stil works only in “ASUS front panel USB 3.0 BOX”
Maybe backward compatibility chip is broken?
She was bootable for DOS, but works fine half of year
