When I tried to use disklabel from 2.2.6-STABLE, it simply segfaulted. It seemed from reading the man-page, that `-w' should just write the table out after figuring the parameters out _without reading the disk_. >How-To-Repeat: Hard -- you need to hose your disk in some special way. My machine did it for me and would not tell me how. >Fix: Nuke the first several sectors with ``dd if=/dev/zero ...'' I had a swap partition on that disk prior to the precious file system I tried to restore, so I did not worry about nuking too much. After this, I was able to auto-create the disklabel and edit it to access my FS. I used to mount it as sd1s1e. Well, now it is /dev/sd1e, but I prefer it this way -- shorter... >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
