    Hi!

    I've just bought a new 60gb Hitachi 7k100 off eBay which was being sold as "used".

    When I check the S.M.A.R.T. data, it reports as little as 20 hours of usage (my usage !)

    Is the s.m.a.r.t. data reseted when you change the drive from a computer to another ?

    Is it possible to reset that counter to zero ?

    Or the drive is basically brand new ?

    I don't think SMART data is deleted when a drive is removed - I think the info is stored solid state somewhere on the hard drive's PCB.

    This is interesting actually. I think SMART depends on a relationship between the BIOS and the hard drive, so I wonder what info is permanent after removal. Test it out!

    I still have the old drive, and I have an 2.5" to 3.5" adapter ... I might be able to compare the S.M.A.R.T. readings on my desktop and on my laptop for the same drive !
