one folder from external hardisk disappeared after failure to open

[nodame]

I was using a seagate backup plus, (NTFS format). I plugged into a windows 8 laptop, and tried to open a sub folder in the main folder. however it can't be opened and there is an error message something like "the directories cannot be found" or "the folder is not located locally/on this disk".

I tried opening other sub folders and they could be opened. When I went back to the main folder, I found the folder that can't be opened previously disappeared.

I've tried:
looking in recycle bin
changing setting to show hidden folders/files
plugging into a macbook to see, which was used yesterday to transfer some video files into the missing folder.

all don't work. please suggest how to recover the data in lost folder

Try plugging it in to a different computer, preferably one that's running Windows 7.

Oh, and keeping your data backed up in future wouldn't be a bad move either.
Otherwise, when that Seagate fails (as it surely will one day) you've lost the lot, not just one folder!

Tip: In my experience Seagate externals are very unreliable and prone to early failure. Avoid.
