Cannot access my possibly corrupted 128gb flash drive

Hello,

I have reason to believe that my PNY 128gb flash drive has become corrupt, and the primary partition has become damaged. I cannot format it, and every attempt to fails. It creates a spam of errors telling me to format it on my windows 7 computer, and on my windows 8 laptop, it reads as "Removable Disk (H:)", and flickers between a hard drive icon and a blank document file icon constantly. I cannot access it, I cannot right-click it without the menu immediately going away, and Disk Manager freezes every time the drive is plugged in to either computers. I would really like to use this flash drive, and I'm hoping it's not ruined beyond repair. Please help!
