Some days ago I’ve bought a part of Hitachi HDDs (Hitachi Ultrastar A7K2000). The seller offered those disks as NEW (not as refurbished). But if I took a look at S.M.A.R.T report of those disk I’ve seen that there are some strange entries.
There is “Power on hours” 0 (like for a new disk) but there are also some test reports form the past (28390 hours ago = years of power on). And there is a lot of log entries from the same time (years ago).
Might I kindly ask you to help to interpret those values? In my opinion someone removed the the most of S.M.A.R.T data but some of values are keept on disk (above logs and tests result) abd was unable to remove it. Next the seller sold this used HDD as a completely new?
Will you be able to confirm my suspicions? I need this to negotiate of return of those disks. Your help will be very appreciate for me!
