MacOS'da Disk için S.M.A.R.T Kullanımı

MacOS’da ön tanımlı olarak gelen herhangi bir Disk durumunu belirten uygulama göremedim ben. Disk durumlarını sorgulayabilmek için brew ile gereken uygulamanın kurulması gerekmekte

brew install smartmontools

Kurulum tamamlandıktan sonra aşağıdaki komut çalıştırılır.

Sudo smartctl -a /dev/disk0

Aşağıdaki gibi bir çıktı verecektir. Disk hakkında tam detaylı bilgiyi bu sayede çok basit bir şekilde alabilirsiniz.
