My family has a 250GB external USB hard drive. We have thousands of photos and important documents saved to it. Recently, I tried to access the files so I plugged the hard drive in and turned it on. Everything opened as normal but when I want to see all the files, I could see the correct amount of folders that we had but all of them had no titles except for saying "recycled." I could open some of the files and they would have little white boxes where the pictures used to be. I immediately thought that it was my computer not reading it correctly so I plugged it into our other computer which is a iMac (My other computer is windows 10 btw). So once i plugged the hard drive into the Mac, it showed up and when I opened it that time it had NOTHING. No folders,no white files, Im really concerned about this and I need help. Any suggestions? I have a feeling that someone pulled it out without ejecting it first and it corrupted it. Please help.
