I have a Verbatim 53018 Store n Go 1TB USB 3.0 2.5 Inch External Hard Drive.
It's formatted as FAT32. I attempted to copy 4GB or larger HD video file to the drive, Windows gave me an error.
I typed "convert f: /FS:NTFS" to the CMD. It seemed okay when it's done. Then I double clicked the drive and came across "this folder is empty". When I turn back to "Computer" the disc seems fine "410 GB empty, 931 GB general"
and the disc is still Fat32. :S !?

I don't want to lose all my data by formatting.
I just wanted to change the format to be able copy larger files. I didn't do anything wrong.
Is there any solution to be able to get my data back become visible?
