I'm preparing an ADATA S102 Pro 16 GB USB 3.0 flash drive to holding a Windows 8 installation for a new computer. Following a guide, I'm told to clean the drive using Diskpart in Command Prompt, but as I enter the command it returns "Invalid Function". At this point I notice Windows (7) is no longer recognizing my flash drive. So I replug the drive and it shows up, Windows says I need to reformat it. I try, it says "Windows cannot complete the format". If I go around this and format/create a new volume using Disk Management, Windows will recognize it again but using clean/other functions in Diskpart causing Windows to stop recognizing. Is there anything I can do to fix this?
