I use metastock data on hard drive, Now how I can go back to Stockalyze own date to use it.
I didn't get your question. Do you want to use Metastock data in Stockalyze? You can change the data format in Stockalyze, just go to Data->Change Database... and change the format to Metastock.
In case you were asking something else or you need any other help please let me know.
