CCD Issues

[Cameron Brunner]

Well my CCD was working fine for about 2months until I rebooted, i'm not exactly certain whats wrong now but im dreading the fact that it might be dead.

The array strip was on 3 'old' Seagate 9gig SCSI hdd's, here's as much info as i can work out.

FreeBSD 4.5-STABLE from April 2002 sometime, it's generally VERY stable.

da0 is the boot disk, da1 da2 and da3 were the raid array and da5 is another disk that had a backup of most things off of the ccd incase this happened. da4 exists but the drive itself has stopped spinning, i havnt had time to get it pulled out of the system yet. da0 and da5 are both already mounted fine and working as normal.

Any and all suggestions welcomed. I would like to revive the CCD if at all possible but if it isn't possible then I just need to know this so I can work on rebuilding the lost data.
