Even if you install a brand new HDD on your PC, it may give out only after a few weeks of operation. It is pretty tricky to determine how long your hard drive will last. Why You May Need to Check the Health of Your Drive But before we begin, let’s go over a few telltale indications of a bad hard drive, so you can spot the issue before it’s too late. In this article, we will go over 5 proven methods used to check hard drive health, so you’re never caught off-guard and lose all your data. This is why you need to make sure that it is running optimally from time to time. Since your hard drive contains all your important files, it cannot be swapped out like other hardware in case something goes wrong with it.

#Disk health check code
When a disk is monitored using a custom script:Įxit code is 0 : Health = (disk health calculated by S.M.A.R.T.) * 100%Įxit code is 1 (warning): Health = (disk health calculated by S.M.A.R.T.) * 50% This means, when the current health is 90%, 9% will be subtracted. parameters, which have a predefined by manufacturer threshold value, also affect disk's health: after decreasing below the threshold, this parameter subtracts 10% from the current disk health. attributes affecting the health value with their weights and maximum limits. The following table contains the health related (critical) S.M.A.R.T. Spin Retry Count = 12 (attribute value), weight = 2, limit = 50.Soft Read Error Rate = 30 (attribute value), weight = 1, limit = 20.
attribute_value - current parameter's value.limit - limit of each critical S.M.A.R.T.Weight - weight of each critical S.M.A.R.T.П - the product of minimums from (limit, attribute_value*Weight) - calculated for each critical S.M.A.R.T.The overall disk health is calculated by the formula below:ĭisk health (%) = П (100% - (min(limit, attribute_value*Weight))) A weight of an attribute defines how important the parameter's value decreasing the affected the disk's health. Such attributes have a predefined weight and a maximum limit value (see a Table 1 below).Ī limit defines how much the attribute may decrease an overall health value. parameters considered by Acronis Drive Monitor as critical for a hard drive (if they are available for monitoring, it depends on the manufacturer), decrease the calculated health status of your disk. Initially a hard disk has 100% health condition.Īll S.M.A.R.T. This will help you to protect your data before your disk fails. Health status warns you of disk degradation, when S.M.A.R.T. The calculated hard drive's health shown as percentage provides you a better visual representation of S.M.A.R.T. Disk health calculation by Acronis Drive Monitor Description
