In my humble opinioin all these three disks are ok.
Thanks again

What is the output of cat /proc/mdstat after running the readwrite below?
Did you try the --run option?
You need to make sure the array is active/running before you try to
mount it.
BTW, has anything else happened to the array, other than the drive
that failed?
Probably should have asked for this before, but what is the full
output of smartctl for each drive, also mdadm --misc --examine
/dev/sd[bcd]1 (or all three relevant devices)?
Regards,
Adam

Still the same. Nothing seems to have changed.
Same answers for mount commands.
