Solve wd1600aajs FW/0MB problems with MHDD & HDDL

[hdd07]

Hi all,
I have the WD1600AAJS-M0A0 with SA problems and gets 0 MB.
The models with problems are, 29h, 52h, 7Bh and F6h.

I tried to use MHDD with script to regenerate the translation, but seem not work.
[1] what models are they for 29h, 52h, 7Bh and F6h?
so far I know that 29h is the smart log.

[2] Am I use the right script?
-----
reset
waitnbsy
regs = $45 $0b $00 $44 $57 $a0 $80
waitnbsy
regs = $d6 $01 $be $4f $c2 $a0 $b0
waitnbsy
checkdrq
sectorsfrom = mwtrrec.bin
waitnbsy
regs = $d5 $01 $be $4f $c2 $a0 $b0
waitnbsy
checkdrq
sectorsto = i
------
3] should I fix the models first before running the script?

Thanks in advance.
