HEy can one zero fill, or erase a DOM disk on module to return it to factory settings? I have a security dvr from avermedia which has crashed and am trying to restore it. But when I downdate the os gui dvr it holds my old settings. It is the dx5000 series http://www.aver.com/2005home/product/dvr/linux/dx5000/dx5000.shtml I know contact them I am trying, but just playing till then, curious also. the os ended up locking me out even as root. Also why can one not boot from a dvd iso bootable zero fill utility, just a cdr? Cdrom is a dvd reader btw tia cjae

Try downloading a Red Hat ISO from linuxISO.org or a mirro close to you. Then when your burn it off to a CD reboot with it in the tray. See if you can boot it in failsafe or rescue mode. lammas cry¿?rp$
