well running smartctl to disk with bad sector. smartctl -t long /dev/sde after finish smartctl -a /dev/sde .... .... ... SMART Self-test log data structure revision number 1 # 1 extended offline completed: read failure ......... LBA_of_first_error 22549777 # hdparm --read-sector 22549777 /dev/sde i/o error # hdparm --yes-i-know-what-i-am-doing --write-sector 22549777 /dev/sde After that i can read the sector # hdparm --read-sector 22549777 /dev/sde 0000 0000 ..... etc etc #smartctl -a /dev/sde Reallocated_Sector_Ct 0 seem like sector fixed and not relocated. Still the fsck.reiserfs --rebuild-tree /dev/md4 say input-output error, so i am searching for more bad sectors. I know what is the bad sector (fsck say 2328735), but i need translate to LBA sector, and still i dont know how do. ( i found on internet but i close the tab jejejjeje) Best regards Christian PD:what is top posting and how i can avoid? hotmail givme 2 options: Reply, and Reply to All NO responda a esta casilla de email, favor de responder a: sch@xxxxxxxxxxxxxx be free, be linux ---------------------------------------- > Date: Fri, 4 Apr 2014 16:17:03 +0200 > From: swmike@xxxxxxxxx > To: sdvileskis@xxxxxxxxx > CC: schnet@xxxxxxxxxxx; linux-raid@xxxxxxxxxxxxxxx > Subject: Re: Problem Syncing raid1 > > On Fri, 4 Apr 2014, Scott D'Vileskis wrote: > >> I apologize if my relatively simplistic summary of what may actually >> be happening left out the detail of pending sectors.
