Retrieve Data/Pictures from Sandisksecureaccess vault

I recently made a bootable usb drive for windows 10 but in hurry i forget to save the data which was on the usb drive , so when the bootable usb drive become for windows 10 , everything on usb go somewhere (i dont know where)

Is there any way to recover the pictures i kept in sandisksecureaccess … 

first thing i not made the backup… 

second i used some softwares which are available on internet to recover data from formatted usb drive , and yes I am able to recover every thing which i formatted but not which i kept in the vault.

So, is there any way by which I can recover the pictures i kept in vault. or i should forget about them

I would say it’s unlikely Sam.  Sorry.
