I recently went through my pile of computer components (dusty garbage) and found that I got a lot of 5~7 years old sata drives lying around.

I found a couple of 400gb sata drives are from around 2007 - and they got an average Power-On Time of around 7 months.

Question Which SMART values from a the drive diagnostics table are the most important to predict an hardware failure?

Can't find any data on what's the industry average before a drive gets an hardware failure.

Thanks in advance

  • The most important and really the only statistic I worry about how many reallocated sectors exist. Simply stated this number indicates how many sectors had to be moved because an existing sector was determined to be bad by the firmware. – Ramhound Feb 8 '14 at 16:11
  • Thanks, so it seems that does relocations typically start to happen before an major h/w failure, correct? – PJJ Feb 8 '14 at 16:19
  • A working hdd typical has a very low amount of sectors it believes to be bad or none at all. A failing drive will often detect a large amount of sectors, and this fact, will often lead to the hdd spending a large amount of time moving files off "bad sectors". Most of the time this can result in your system crashing, files becoming corrupt, or your system feeling like its "slow" – Ramhound Feb 8 '14 at 16:52
