Obtaining key attributes and Health of HDD and SSD using smartmontools
DESCRIPTION:
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 HDD and SSD health status and also its key attributes
import os
#device record
class DeviceRecord:
def __init__(self):
self.deviceHealth = None
self.deviceAttributes = None
class SMART:
#to run a smartctl command
def RunSmartCtl(self, strArgs):
#get the command with strArgs as the argument
cmdString = "smartctl " + strArgs
#get command output and store each line in a list
output = os.popen(cmdString).read()
lines = str.splitlines(output)
return lines
#get device health
def GetDeviceHealth(self, deviceId):
deviceInfoLines = self.RunSmartCtl("-H " + deviceId)
return deviceInfoLines[-2]
#get device attributes
def GetDeviceAttributes(self, deviceId):
deviceInfoLines = self.RunSmartCtl("-A " + deviceId)
for i in range(len(deviceInfoLines)):
if deviceInfoLines[i].startswith('ID#'):
index = i+1
break
infoDict = dict()
for i in range(index, len(deviceInfoLines)-1):
x = deviceInfoLines[i].strip().split()
infoDict[x[0]] = x[0:len(x)]
return infoDict
if __name__ == '__main__':
smart_features = SMART()
deviceid = input("Enter device id: ")
#fetchig disk health
devHealth = smart_features.GetDeviceHealth(deviceid)
#printing device health information
print("Disk Health Information")
print(devHealth)
#fetching attributes details
devAttr=smart_features.GetDeviceAttributes(deviceid)
#printing attributes information
print("Disk attribute Informaion")
print("ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH")
for attributes in devAttr:
print('\t'.join(devAttr[attributes][:6]))
