Try sudo modprobe md_mod to load the MD driver, then check /proc/mdstat. The -Q info does not look promising. -dsr- -- http://tao.merseine.nu/~dsr/eula.html is hereby incorporated by reference.

Re: Linux Raid Partitions
Hi Dan, Thank you for your reply. /proc/mdstat -> no such file or dir /dev/md0 -> no such file or dir mdadm -Q /dev/sdb2: -> device 0 in 2 undetected raid1 mdadm -Q /dev/sdb4 -> device 0 in 2 undetected raid1 mdadm -A /dev/md0 /dev/sdb2 /dev/sdb4 => mdadm: error opening /dev/md0 How do I create /dev/md0? Thanks for your help and patience.

Linux Raid Partitions
Hi All, I have a drive out of a Western Digital Mybookworld World edition drive. cfdisk -Ps /dev/sdb tells me that there are four partitions and this drive and that the file system is "Linux raid" on all four partitions. How do I mount this partitions so that I can copy the files on this partition onto another drive? Thanks in advance for your help Yours Sincerely Stephen Grant Brown <>
