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.
