Tryed OS reinstall --> and that diden´t work (same Status: Corrupt root") 

so i tryed --> Factory default --> and that diden´t work (same Status: Corrupt root") 

so i tryed --> ERASE all data --> and that diden´t work (same Status: Corrupt root") 

so i tryed --> Switch possitions on HDD and then Factory default --> and that diden´t work (same Status: Corrupt root") 

Then i have tryed Factory default a cuppel of more tryes but it allways goes back to Corrupt root.

Try putting the drives into a PC, and zeroing them with the vendor disk diags (both seagate's seatools and wdc's lifeguard can do that in their "advanced" tests).

IS it maby possibel to load / upgrade firmware from USB memory?

There were two problems here.

1. The firmware on the flash was corrupt, so the factory reset would have failed as a result of this. I fixed this. Whilst USB Boot Recovery could have been used to fix this particular problem there may have been some side effects.

2. One of your disks appears to be bad.
