I do know the SCSI drives have their own bad block table but it appears from the description of the SCO OSR5 badtrk utility that OSR5 may also maintain an OS level bad block mapping capability as well. I still would like to see the SCSI bad block table but I cannot expect Linux to support what might be an SCO OSR5 specific feature. > I've also been using this for YEARS on > SGI's under > IRIX. Ahhh IRIX, I remember it well but it has been many years since I worked on SGI hardware. Well made and well supported. I hear they may be making a come-back. That will be interesting to see. > Under IRIX, the command `fx' is used to partition SCSI > drives, exercise > them, format them (which is something one never does to SCSI > drives), spare > out bad blocks, list the bad block table, etc., etc.. I never had the opportunity to work at that level. That was handled mostly by the SGI techs. This does bode well that I may be able to get at this data in Linux if I can just find the right utility.
