Which tool is safest?

Just right click on the drive, select properties, go to the tools tab
and "check now." Check both boxes and push START. It'll complain the
disk is in use and ask if you want to schedule a scan for the next
reboot. Say yes and reboot.

It'll take quite a while depending on drive size and speed of the
machine.

Surface scan and choose both options:
Automatically fix file system errors
Scan for and attempt recovery of bad sectors
Click Start. It will schedule the surface scan for the next reboot of the
computer.
