Hi, I've some unreadable sector on a Samsung SATA disk. The output of "smartctl -a -d ata /dev/sdc" shows 2 pending sectors: 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 2 the offline smart test also logged the error: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Short offline Completed: read failure 90% 2835 54754753 and I got the following kernel message if I try to read the sector with "dd if=/dev/sdc skip=27377376 bs=1024 count=1": kernel: res 51/40:00:c1:7d:43/23:00:03:00:00/40 Emask 0x409 (media error) <F> But there's no buffer error, I always get the content of the sector after 6 "media error"! The disk is member of a raid5 array, but I cannot force the re-write of this sector, cause there's no read error. The array is slow when the read runs into this sector and I'm not sure that the content what I get is correct. What should I do? Should I fail and re-add the disk? kernel 2.6.24 intel AHCI sata ctrl.
