Drive data

I copied my libraries to the external drive. I then disconnected it and re-installed windows 7 and then all my programs. I hooked up the external drive again and it doesn’t show all the files. However, when I look at the properties of the drive, it shows the proper ammount of space used to correspond with all the files I saved. How can i get to those files?

sounds like the drive is corrupted

you will need a recovery software to retrieve the files

try recuva or testdisk
