Sure, quit thinking like a Windows user!
Running an unnecessary check frequently could possibly be more harmful
than good, plus you just don't need to do it! Turn on Smart disk in
your bios, as this will test the disk on startup and let Linux take
care of the rest for you. The file system is better, the OS is better
and will keep you better apprised of what's happening with the
hardware.
