    SubjectRe[2]: Urgent SCSI I/O Error
    Hi All,

    If the Hard Drive is died, means I will need to replace. I have backup
    for the Data in that /www partition.

    Means when I replace new HDD, I will have to partition/format using
    fdisk /sda ?

    From my partition info,

    /dev/sdb6 917072 732972 137516 84% /
    /dev/sda1 18820 5811 12037 33% /boot
    /dev/sda6 2218336 462492 1643156 22% /www
    /dev/sda5 5297560 418936 4609520 8% /home
    /dev/sda7 1210440 711516 437436 62% /software
    /dev/sdb1 5550188 50896 5217356 1% /usr
    /dev/sdb5 2016016 28572 1885032 1% /var


    My problematic HDD is /sda so if I replace this HDD, how can I boot as
    boot images are in /sda1 /boot partition. How can I copy this boot
    images to somewhere and make it work and what will be the process?

    I know if I reboot and replace the HDD, it will give problem while
    booting, any Idea to struggle with this?

    Thanks a lot for all your help.

    Regards
    Manohar
