WD20NMVW-11AV3S2 with sed problem error

[Navafigo]

Hi , i have this model with error sed.

When I try to take the step of "upload dir into HDD RAM" i can't execute it because i get this error.

Any idea?

This means that there are likely issues reading module 1 off the surface:

1. Damaged heads
2. Damaged module
3. Damaged surface
