Here's exactly what I did:
I have a 3TB Seagate hard drive that I primarily use with my Windows 8.1 machine every day. I turned off that computer, unplugged the drive, and plugged it into my Windows 7 laptop. I moved (not copied) about 2GB from C:\ImportantPhotos to the external drive to Z:\Photos\Unsorted. The files moved in about 7 minutes. They were gone from my Windows 7 laptop and appeared fine on my external hard drive.
I then plugged the hard drive back into my Windows 8.1 primary machine and turned it on. When I went to navigate to the Z:\Photos\Unsorted\, I saw ImportantPhotos folder and was pleased to know this was a success. I mean, why wouldn't it be? However, when I clicked the folder it gave me an error about the folder not being available, and now the folder is completely gone. I tried to view the folder back on the Win7 laptop, and it was still missing completely.
Where did my files go? Did I lose them completely
(Possibly relevant: There was definitely activity on the external drive, as the parent folder (Unsorted) shows Date Modified time of exactly the time the files were moved.)
THANK YOU for any help help! My engagement photos are on there!!! If you need any more information at all, please ask!
