I'd been suspect of it for some time now, but finally confirmed it with a reinstall to 5.2.1 when GEOM started removing it for me ;) Some more tests with smartmontools (http://smartmontools.sourceforge.net/) indicate read failures at the same position on the disk. This problem is made worse by the fact that this is a 100GB disk, part of a Vinum RAID-0 array (together with two more 120GB disks). I have managed to get my hands on a 123GB disk for backing up the data to to. I know I am going to have to use dd for this, but this is something I've never done before (short of a quick flirt with floppy images, etc.) Since GEOM has previously removed the volume when it hit the bad area I need to know if I can disable this to recover as much data as possible (some is better than none). If this requires installing 4 then that's how I'll have to do it. Basically I would like to ask -questions if anybody has any advice (other than ``you should have made backups'' -- I was in the process of buying a 3Ware RAID card for this purpose ;) as to how I should go about this. Anything at all... I'm pretty desperate at this point!
