Alright buddy, now that you met this problem, why not take care in next time?
I think you'd better install a backup software, because data recovery software doesn't work every time. Right?
Now my idea is to download and install a backup software. Here I recommend you
PCNumen Backup:
PCNumen - all the software that protect you from computer disaster? data loss, ect.
CVBackup:
CVBackup - Convenient Backup Software, the best backup software for home and business use.
