I know that a read-only test does not remap sectors.(*) That's why I use a read-only test to CHECK for errors. (*) Actually, I suspect that drives will remap sectors if they encounter errors but are eventually able to read a sector. > A qualified yes.

The point is that this is not a new error, so it's pretty odd that smartd chose to report (re-report?) it, and it certainly doesn't look like the drive is in imminent danger of failing. -- ======================================================================== Ian Pilcher [email protected] Sent from the cloud -- where it's already tomorrow ======================================================================== ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
