It is very minor, all drives are made with the ability to have spare sectors to be used in the event there is a bad read/write to one and it just is reallocated.
Rydia, is this warranty case? Should I return unit for support? If it will grow, which number of Reallocated Sector count critical?
It would be a massive number to require concern in the hundreds or thousands. You can warranty the device any time you feel the need. The process is just done on our website. Support > Warranty & Returns > Warranty Returns
Thanks for information, I’ll be watching progress of grow this number
