Thank you.

I plugged HDD to my Macbook and now it disk2s2

MacBook-Air:~ evgeniy$ sudo fsck_hfs -f /dev/disk2s2
** /dev/rdisk2s2
Executing fsck_hfs (version hfs-305.10.1).
** Checking Journaled HFS Plus volume.
Invalid B-tree node size
(3, 0)
** The volume could not be verified completely.
MacBook-Air:~ evgeniy$

I used command from your manual. "fsck_hfs -r -d /dev/disk2s2"

MacBook-Air:~ evgeniy$ sudo fsck_hfs -r -d /dev/disk2s2

If it doesn't improve after another fsck, you will have to use PhotoRec to recover your data, but it will not recover the original filenames.
