Corruption on external disk - strange behavior

I have a media jukebox device with an internal drive bay that can accommodate SATA drives, and have a bit of a mess this weekend. The media jukebox is designed to be used with a TV, but I occasionally remove its disk (it has an "eject" function like Windows so that you can proceed safely) and do a little housecleaning/additions/deletions on my 4tb disk while plugged into a USB hard drive dock on my Windows 8.1 workstation.

99% of the time, there are no problems when managing this NTFS formatted disk on my Windows 8.1 computer. Today, that changed.

As soon as I plugged it in, I immediately noticed that I could not navigate into any of its directories. I received a "parameter is incorrect" message when trying to do so. I ran a "chkdsk /f /r" against the drive, but since the drive is so large, it took awhile. During that time, my computer crashed and chkdsk was interrupted.

Here is where it gets complicated. After I got my workstation back online, I checked the same disk and found that a directory I used for the DVD and Blu Ray rips of my collection (yes, I still actually buy physical media) was now listed as a file. For example, my "movies" directory was now listed in Explorer as a file with the same name.

I ran chkdsk again with the same parameters, and this time it ran to completion without interruption. After chkdsk completed, the movies directory was still listed as a file. I also couldn't access many of the files located in other directories on the same drive. I can navigate and view what's in each directory, but about 50% of the files (randomly) couldn't be launched. This includes pictures, music, videos, Office documents, etc. When trying to launch, I receive errors like "cannot render the file" if launching via Media Player Classic. Similar types of messages are returned by whatever the native app is for the respective file type.

After chkdsk completed, I turned on the ability to view hidden files/folders and noticed that there's now a "found.000" directory. Inside of that directory, there's a number of subfolders (dir0000.chk, dir0001.chk, etc) that appear to contain the contents of the previous mentioned "movies" directory that now appears as a file. While I can't browse this "found.0000" folder via Windows, I was able to browse when using EaseUS Data Recovery Wizard. I was able to restore a couple of the files as a test, some were accessible afterwards, but some weren't.

I'm trying to solve the corruption problem for the drive in general, as I'm not sure what event just resulted in the drive getting hosed to this extent. Any ideas on how to fix?
