[smartmontools-support] Question about reallocated sectors

[Bas M. <ab...@ba...>]

Hi,

I've a few of the following disks running. They show a number of 
relocated sectors. I never saw these on other drives. Is this something 
to worry about? The disks are hardly used (daily backup) and used in 
perfect conditions.

Regards,

Bas.
