RecData and a_disk_identifier_bc.platform

Hi,

Every drive connected to my pc, including drives shares on my NAS have a folder named RecDate and a hidden file name a_disk_identifier_bc.platform.

Norton does not seem to see it as a virus and I cannot find any reference to it on the internet.  The earliest dates of the folder and file is 03/22/2015. But any new drive I plug in get them both with the current date.

Anyone have any idea how to find out what this is?  It's freaking me out.

 

Many Thanks
