WD 2TB Elite with Corrupted MBR

I have a friends WD 2TB MyBook Elite that had it's HW die in the casing. I am trying to recover the data, but I am afraid it might be too late. Running the commands to view the boot sector tables should the typical:

`bh@ubuntu:~/Documents$ sudo file -s /dev/sdb
/dev/sdb: DOS/MBR boot sector MS-MBR Windows 7 english at offset 0x163 "Invalid partition table" at offset 0x17b "Error loading operating system" at offset 0x19a "Missing operating system", disk signature 0x485f11c2; partition 1 : ID=0x7, active, start-CHS (0x0,32,33), end-CHS (0xc,223,19), startsector 2048, 204800 sectors; partition 2 : ID=0x7, start-CHS (0xc,223,20), end-CHS (0x3ff,254,63), startsector 206848, 3906820096 sectors`

I have run variations of the different commands and also @themaddoctor script to search the boot sector for the lines to try and get the keyblock, but nothing is turning up with the right information. Before I go wasting hours on this, is this a lost cause? Thanks.
