That is the info in the terminal when we powered off and on the drive.From the picture,it looks like a CELOG problem.Generally,this problem is caused by corrupted Log modules and can be easily and well solved by CE Log Repair of HD Doctor for Seagate.You can get the detail from this link.

After took a CELOG REPAIR,we could see such info in the terminal.Then we try N50,,22 and found that drive can’t get into level 50 properly.As far as I know,that is because there are many errors in this drive and just click the CELOG REPAIR button is not enough to solve this problem.However,it will cause the drive can’t go back to the level 50 after CELOG REPAIR.

So we decided to solve this problem by commands.

1st.Press Ctrl+R to load the cert table module.

2nd.input N4E,,22 and click Enter,press Ctrl+L to initialize the selfscan.

3rd.Input N50,,22 after the selfscan finished.

Then go to the Sector View Tab and we found the sector can be accessed properly.Just connect the drive to the Data Compass to get back the data.
