It crashed this evening. Whenever I try to run fsck on one particular partition, I get the following message: ** /dev/rsd0s1e BAD SUPER BLOCK: NCYL LESS THAN NCG*CPG pid 161 (fsck), Uid 0: exited on signal 8 floating exception - core dumped First of all, why does fsck dump core when performing this operation? Second of all, is there any way I can retrieve the information off of this partition? Our backup system is on the blink, and it is imperative that the information in this partition be extracted. Can I relabel the disk in order to validate the superblock information, or is that a newfs operation only? The problem is that newfs will erase all of the old info. I am desperate to restore as much information as I can. Is there anyway that I can use the raw disk device as an input file and dump the information onto another partition, or into a file? Any help would be warmly accepted. Josh Pincus
