Browser-Based HDD/SSD Health Analysis.
Hard drives report their health using a system called S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology). You can read this data using command line tools like smartctl, but the output is often hard to read. Manufacturers store data in raw hexadecimal values. A read error rate might look like 0x00000ab42 in a terminal. This could be zero errors, or it could be thousands, depending on how Seagate, WD, or Toshiba encoded the data. This viewer attempts to decode those raw manufacturer-specific values to tell you if a "high" number is actually bad, or if it is just a routine counter.
