HDD vol. gone new linux part appeard

[matador007]

Hello team cgsecurity,
meanwhile reading testdisk manual i thought that maybe here ill get some clue.

External HDD has been connected to sat-tv decoder. After that it has been unreadable from PC Windows. BIOS see it I can locate disk using diskpart, but volume and NTFS partitions are gone and linux appeared



I can't run chkdsk and running out of options.
