Unplugging a drive while on use is a huge mistake. You have corrupted the partition by doing so. Using a data recovery software should help but if the partition table is too messed up  you will need a Data Recovery Software. 

thanks your reply  but now i just use the   some recovery software like but it can’t access my passport driver . has another advise?

Try using another software or take it to a Data Recovery Company.

Just take it to a data recovery facility as DIY data recovery jobs often cause more harm.  Spend the money so that your data is recoverable.
