Date: 12 Sep 1996 03:44:25 GMT Organization: Concentric Internet Services Lines: 18 Message-ID: <5180up$gbo@herald.concentric.net> NNTP-Posting-Host: voyager.cris.com X-Newsreader: TIN [UNIX 1.3 950824BETA PL0] I am running FreeBSD 2.1 from an Adaptec 2940 SCSI controller. Recently I am finding messages like these in /var/log/messages: Sep 11 20:02:44 dnn /kernel: sd0(ahc0:0:0): MEDIUM ERROR info:208003 asc:11,0 Un recovered read error sks:80,1e Sep 11 20:02:47 dnn /kernel: , retries:4 I assume it means that my root disk has a bad sector on it. How do I determine (decode) which partition (slice) it is on, which sector it is. Are there tools in FreeBSD to remap that sector on the fly or must I reformat the disk ? What is the best thing to do ? Thanks.
