Obtaining primary information about HDD and SSD using smartmontools
INTRODUCTION:
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; written as SMART) SMART is a system for monitoring and early detection of errors of storage media such as hard disks or SSDs.
All current hard drives and SSDs have SMART functionality. However, the data provided by SMART, (SMART attributes), are different from manufacturer to manufacturer
NOTE: Run IDE as administrator and SMARTMONTOOLS should be installed in the system
IMPLEMENTATION:
This python script displays the primary information about the HDD and SSD present in the system
