I am considering some disaster recovery scenarios.

Lets assume my MDF is gone - the disks are dead.

The LDF is on a different disk channel. Lets assume its fine.

Can I make a "final" TLog backup from the "good" LDF file?

Maybe copy some-earlier-MDF file into place, would that enable a TLog backup from the LDF file?

'Coz if I can then I could use that as a route to getting a zero-loss recovery - make a final TLog backup, and then restore the whole lot from last FULL + All TLog backups thereafter.

You can make a "final" TLog backup from the "good" LDF file.

For example:

BACKUP LOG Database4
TO DISK = 'D:\SQL\Database4Log.bak'
WITH NO_TRUNCATE
