Just precleared one of my Samsungs that I had laying about, I think from the numbers in the start and finish files it looks okay but the "pending re-allocation" parts in the report is what concerns me.
I've also attached the start and finish files from the preclears if that is needed.
Any insight as to what I should do with this drive, and perhaps a little understanding of what the last paragraph means for future preclears would be appreciated, thanks.
