I have a file server running by samba.
I have a suspect that my hdd has a bad sector and will be crash sooner as I get IO Error most came from hdd6 and hdd8.

My idea is to replace it. I have an 80GB hard drive. How do I replace it?

Is it ok to format my 80GB and partition it to /home, /data/dept and /data/public and remove the old hard drive and replace the new formatted hard drive ?

Would you think this will work?

This is my snippet of my df

Filesystem Size Used Avail Use% Mounted on
/dev/hda2 1.9G 749M 1.0G 41% /
none 125M 0 124M 0% /dev/shm
/dev/hda3 3.5G 2.8G 528M 85% /var
/dev/hdd6 14G 9.6G 3.5G 73% /home
/dev/hdd8 31G 28G 2.5G 92% /data/dept
/dev/hdd7 10G 7.8G 1.8G 81% /data/public
/dev/hdc5 73G 64G 5.9G 92% /data/dept2

What you don't want to do is copy everything over to the new drive, take out the old drive, and then discover that you have a lot of problems and a big mess on your hands.

I would place the new drive on a new address and run it in parallel with the old drive. Set up 3 partitions on the new drive. Then copy hdd6 to the new drive. Switch to using the hdd6 on the new drive. If it doesn't work switch back to the odl drive. Once hdd6 is working OK on the new drive switch hdd7. Then switch hdd8.

After you get all of the hdd data moved over to the new drive the you can start playing around with hdd and try to permanently fix the problem with hdd. Run bad blocks on hdd, repartition hdd, reformat hdd, and so on.
