G-List is cleared successfully!

But when I read the G-List again I get the same number or larger sometimes.

I need the MBR and MFT badly since the customer wants few files out of full 4tb, when I started imaging the drive it started to give me all black sectors after the imaging hit the first one, which marked the beginning of the partition and the MFT as bad sectors

Try open with Com connection. Sometimes working .
But I think your case not about clear g list .

You have to patch the DD.bin module (if you know how)....

Can you read the tracks?

Why would you touch the P-List if your intention is to recover the data?

[BGman]

Why would you touch the P-List if your intention is to recover the data?

The OP has said nothing about data recovery...
You should ask him the same question about the G-List.

Wow ,
Brain Antenna Says Post If About Data Recovery Lol . Also i wanted to ask thread starter do all your heads read fine in different area of srive like 25% 50% 75 % and 100% i reverse

[BGman]

No. It says conventional hard drives, which means Data Recovery and HDD Repair.

[Amarbir[CDR-Labs]]

Well,
There is a typo above " Wow ,Brain Antenna Says Post If About Data Recovery Lol . Also i wanted to ask thread starter do all your heads read fine in different area of srive like 25% 50% 75 % and 100% i reverse " , I Wanted To Say " Wow , My Brain Antenna Says Post Is About Data Recovery Lol . Also i wanted to ask thread starter do all your heads read fine in different area of Drive like 25% 50% 75 % and 100% in reverse "

I have MQ04ABF100 drive in my hand. MRT doesn't cleaar G list , Also dosen't open P list. even with Com port connection. Maybe MRT still not solve MQ04 architexcture yet. My version is 2.1.3.1

[BGman]

MQ04ABF100 is a SMR drive. Commands are different.

@LostDataSa, could you please upload your resource dump? I'd like to write a tool to analyse the P-list and G-list, but I need to see some working examples.
