Seagate Barracuda ATA IV

[rosepigg02]

Hi there.
I'm requesting help regarding a Seagate Barracuda ATA IV - ST340016A drive that i want to SelfScan.
Drive have some realocated sectors and i want to SS it as an experience, but i need to be able to write back Vendor and ATA when selfscan finish.
So far i've manage to backup those tracks correctly, because i've compared in HEX editor the files that i've downloaded from my drive with the ones for the same moddel under HDDGuru files and they match, so i'm using the right procedure to download the data, but i can't upload it back.
Here is more info :

Barracuda IV - SNOWMASS
Service Area SPT - 0x02B9
Firmware version 3.19,
Vendor data track - 0x700C - offset 0x0C (0x100 sectors)
Buff-R - 0
Buff-W - 10

I'm using ST_Mem to write VENDOR to drive. To test i've changed drive name on STUFF manually to "Spildit" instead of ST340016A. I'm assuming that when i manage to restore the vendor track back the model will revert to default because i'm using a track saved before the changes. I will not risk to start selfscan if i can't find a way to write back to the drive.
