I have an external harddrive to which I thought I lost all of the information on. Whenever I plugged it in, the light would come on like it was going to read and then turn back off again. Whenever I tried to access the volume, I would get an error message saying “Error performing inpage operation.” After looking extensively online, I ran

chkdsk l: /f 
substitute l: for your volume label

It repaired the drive and works great. Off to buy another terabyte hdd for backups. Hope this can be useful for someone.
