yeah i'm compressing via commandline but it's not one step this is the 3 step but only for data3 i used this
arc a -r -ep1 -w.\ .\Disk1\Data3.bin -mprecomp042:v+srep+lzma:a1:mfbt4:d256m:fb128:mc100 0:lc8 "%choice1%\*"
if ERRORLEVEL 1 goto arcfail

the first 2 bins just used this
-srep+lzma:a1:mfbt4:d256m:fb128:mc100 0:lc8
and i have tried what you said and nothing when it comes to extract the data3 it just stop no error massages or any thing else only the first 2 bins extracting perfect
i also tried
PrecompVer=0.42
didn't work
please save my day

EDIT: i have found the problem and solve it thanks every one for helping me
