Final verdict: 9.4/10 – A near-perfect utility, slightly deducted for its old-school interface and lack of cross-platform support, but absolutely essential for data-sensitive Windows users.
Note: Always verify the integrity of downloaded software from the official site and maintain offline backups even when using prediction tools – no software can guarantee 100% prevention of drive failure.
