Perhaps I misunderstood something, but I'm unable to reallocate offline_uncorrectable sectors with the method described in badblockhowto. The disk currently is a member of a raid1 array. I have found the "bad" blocks around the reported sector with the following command: export i=139735500 && while [ $i -lt 139735600 ]; do echo $i; dd if=/dev/hdb of=/dev/null bs=512 count=1 skip=$i; let i+=1; done I have removed the partition (not the whole disk) from raid1 (raidsetfaulty && raidhotremove) and I have zeroed the sectors and soon the whole partition (with sync!) but nothing had happened. I have executed smartctl -t offline /dev/hdb when finished smartctl -t long /dev/hdb but I still have errors when I executing the script that I mentioned earlier: 139735510 1+0 records in 1+0 records out 139735511 dd: reading `/dev/hdb': Input/output error 0+0 records in 0+0 records out 139735512 dd: reading `/dev/hdb': Input/output error 0+0 records in 0+0 records out [..] Regards, Zoltan smartctl version 5.1-11 Copyright (C) 2002-3 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: SAMSUNG SP1614N Serial Number: XXXXXXXXXXXXXXXX Firmware Version: TM100-24 Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: ATA/ATAPI-7 T13 1532D revision 0 Local Time is: Sun Jan 9 21:48:40 2005 CET ==> WARNING: Contact developers; may need -F enabled.
