Recover files from a deleted and erased external disk partition

I had an external disk with two volumes: - Volume A was formatted as NTFS which had videos/photos backed up - Volume B was Mac Extended Journaled - which was used for Mac Time Machine backup. However, Time Machine wasn't working, so I formatted/erased Volume B - not sure what exactly happened, but the NTFS volume was gone too, and now there is just the Mac volume. The NTFS volume with video/photo backup is gone. Is there a way I can get back at least some of the data from that NTFS volume? It had years of backup of videos/photos. Note: - Original HDD was 1 TB with 2 volumes of 500GB - Now there's just one Mac formatted volume that covers whole HDD of 1 TB Any help would be appreciated.
