OK, I get the theory. But AFAICT this drive hasn't remapped *any* sectors. Yet. (Which would not be impossible; it's a relatively new drive, a few months old at most.) Quoting smartctl:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0033 100 100 050 Pre-fail Always - 0 196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 0 197 Current_Pending_Sector 0x0032 100 100 000 Old_age Always - 3 198 Offline_Uncorrectable 0x0030 100 100 000 Old_age Offline - 0
This seems to suggest that there are three *candidate* sectors with reallocation pending, none of which have actually been remapped (yet). If so, drive replacement would perhaps be premature.
I suppose it's time to read up on the details of the SMART spec. -- Chip Salzenberg - a.k.a. - <chip@pobox.com> "I wanted to play hopscotch with the impenetrable mystery of existence, but he stepped in a wormhole and had to go in early." // MST3K - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
