on startup s.m.a.r.t. detects error on Spin-Up Time, Reallocated Sectors Count, Seek Error Rate, Seek Time Performance, Spin Retry Count and Head Flying Hours.. but after 5 mins s.m.a.r.t. says hard disk is perfect and excellent.. what should i do?
Get a new hard drive or submit it for warranty/repair
but why is that, after several minutes it doesnt detect any errors? and says that the condition is perfect?
S.M.A.R.T. doesn't suddenly stop detecting errors on a hard drive. Many of the tests on S.M.A.R.T. are counters, so if it detects an error, you get a 1. If it detects that error again, 2 and so on. If you are getting inconsistent S.M.A.R.T. data reads, the tool you are using isn't working correctly or the hard drive is screwed up. Either way, I wouldn't trust a hard drive with errors.
