ST4000LM024 MCMT Table corrupted : issues during reading sysfiles

[hddr49]

Hi there.

I have a ST4000LM024 who start busy.

Terminal shows MCMT Table corrupted and No HOST FIS-ReadyStatusFlags

I unlock the drive and try to read 348 sys file to go further. (Both 348 & one 21D sys files are corrupted)

Tools -> Utility extensions -> Service iformation objects -> System files
Check the file id I want to save / right click / Read selected to file

When I put terminal at 38400, it crashes after a while with "Terminal : reply timeout error"

When I put 115200 it seems ok.

But I have an error :
Root Sys File 3.348 Rd Err (sect 0x0) !

What the next step ? How can I fix the MCMT table ? and give user area access ?
