That usually means a quick format, which means you have the chance to recover some files. You need to use software recovery like Recuva or EaseUs to see what's on there. But to have your best chance to recover things, you'll need to either put this drive in an enclosure and recover files using another computer or install Windows on another hard drive and use this as a secondary drive. Every second you operate an OS on this hard drive, the less likely you become to recover the file you want.
