If you have a controller which has a nice little bios setup utility, like the later Adaptecs or Buslogics, you can go to "verify media" which will cause the SCSI drive to remap out the block automatically. Then you just make sure to run fsck's on everything and you should be back. -- - Jordan Hubbard President, FreeBSD Project
