Pendrive must scanned shows corrupted

I was transferring pictures from my PC to pen drive and it took a very long time to be done , so being stupid I was I removed it without thinking now the files gone and under my pen drive name it shows "FAT32" or something like that instead of 120gb free of 124gb . Now when I open the the pendrive's file , it shows that it need to be scan and it is corrupted ... So my question is , can I even fix it ?
