Hi there, have you already experienced some data loss ? Well I almost erased accidentally all my stuff and I wanted to share with you an excellent (free) tool for recovery.
Before finding it, I tried some commercial products which showed me the files which could be recovered and 50% looked broken (to recover, you have to purchase). Well this free program just get me back 100% of my data with no loss
EDIT : scroll down to “SoftPerfect File Recovery”
