Default I think I've solved my Spin Retry Count problem

I've also rebooted the system quite a bit more often than I usually do in that time. HD Sentinel is also now
starting to upgrade its Health rating automatically, it had gone down to 40% at its lowest and today it's at 52%.


I've never considered those numbers are very useful, what matters is the raw value.


Well, they seem to be based on the same criteria that we'd use to
judge quality: how many errors are there, and how often do they occur.


The raw numbers for that particular drive dont support those 40% and 52% claims, particularly with a parameter like
spin retry count thats much more likely to be a problem external to the drive than internal to the drive.


Well, HD Sentinel uses some kind of proprietary internal rating equation, which seems to be logarithmic (slows down as
it gets closer to zero).


Its clearly terminally stupid to give that particular drive either
of those numbers to that particular drive when the bulk of
the causes for spin retry counts are external to the drive.

I don't concern myself too much with the absolute values they come up with, just with the relative values.


It makes a lot more sense to do that with the raw SMART numbers instead.

In this case the relative values has indicated an improvement in health has been noted.


But there isnt a shred of evidence that the health of the drive has changed one iota.
