Help a beginner to restore wd400bb

[cambit]

Hey. First time trying to recover HDD. There is a very ancient WD400BB-75DEA0. Want to merge g-list into p-list and clear SMART. To do this, downloaded 43 and 44 module services using IDE terminal and commands: $0 $0 $3 $0 $F $E0 $21 and $0 $8 $26 $1 $F $E0 $21. Here they are: https://file1.uafile.com/755107 , https://file1.uafile.com/267456. Then merged them with the program Plisteditor, the result is a new 43 module: https://file1.uafile.com/907328. Next, the command $0 $0 $3 $0 $F $E0 $31 loaded the module on the disk, then off-on power to the disk and to check downloaded again 43 module and got this file - https://file1.uafile.com/391563 ahhh! What did I do wrong?
