Because it disables any interrupts during doing dump, it can avoid lots of problems LKCD has. Main Feature - Reliability Diskdump disables interrupts, stops other cpus and writes to the disk with polling mode. Therefore, unnecessary functions(like interrupt handler) don't disturb dumping. - Safety Before writing to the disk, diskdump checks its disk partition to confirm whether it is a really dump device. Therefore, diskdump doesn't overwrite filesystems by mistake. Currently, diskdump supports only scsi disk(aic7xxx/aic79xx), but, I'm planning to support IDE disk in the near future. Diskdump can be downloaded from here. http://sourceforge.net/projects/lkdump Please see readme.txt which can be downloaded from this site. Any comments? Best Regards, Takao Indoh
