Testdrive 
icare data recovery 
stellar pheonix 

& now am trying easeus , please guys i need help with this , i bough my passport 1tb wd & i want to recover data on it 
I also read that this is due to corruption of file system & there’s some softwares which can rebuild or rewrite this filesystem & then get hdd to work 
What do experts here say ?! 
Thank you very much guys for your time !

If data recovery software doesn’t work then try TestDisk http://www.cgsecurity.org/wiki/TestDisk Sometimes running the command prompt to convert from FAT32 to NTFS will fix it this link explains how to run the command prompt http://support.microsoft.com/kb/214579 I would use that last.
