Hard drive making odd noises or running hot, and the raw S.M.A.R.T. numbers mean nothing to you? HDDExpert, a free tool from KC Softwares, translates them into plain health and performance ratings for HDDs and SSDs, marks errors in red, and tells you what to do next.
Reading a drive’s S.M.A.R.T. status
S.M.A.R.T. records health indicators reported by a storage device. HDDExpert collects those values and presents them alongside a health overview, so users can see drive condition without having to interpret every raw attribute. The program also surfaces error and performance information, giving technical users details to investigate while keeping the main status easier to scan.
A health reading is a snapshot of information the drive reports. It can point to warning signs, but it cannot guarantee that a drive will keep working or predict the exact timing of a failure.
What drive details does HDDExpert show?
