|Re: [PLUG] Cloning a dying hard drive|
Those instructions are sane. I'm sure folks have different approaches they
would take. My approach would be..
- power down the computer
- attach the new drive
- boot to a USB Kali linux drive
- make sure the new drive is /dev/sdb by doing fdisk /dev/sdb
if this works then 'p' to print the partitions.
'c' to create a new partition (use 1 primary and use all space)
'w' write changes and quit
- mkfs /dev/sdb1
I'd probably use dc3dd which is just a patched version of dd that's intended for
forensics use. It takes the same options, etc.
- dc3dd if=/dev/sda of=/dev/sdb
If there are errors then you can add the dc3dd option, conv=noerror,sync
- dc3dd if=/dev/sda of=/dev/sdb conv=noerror,sync
This will prevent dc3dd, or dd, from halting on error.
That should do it.
You could test by trying to boot from /dev/sdb and see how it goes. Of course you
can also boot as normal and make sure everything you want it on the new drive.
Hope this helps. Let me know if you have any questions.

The hard drive on my home server is starting to give me errors. I actually got a kernel panic today while I was out because of it. I fsck'ed it and it seems OK for now, but that's what I thought when I fsck'ed it a few days ago when I saw errors, too... The machine is old and needs to be upgraded, but I'm going to need a few days to order the parts. As a stopgap I just stopped by Microcenter and picked up a 1 TB HD in hopes of copying everything off the old 1 TB drive before things get any worse. I've done this process at least once before, it was probably like 10 years ago. Does anyone have any thoughts on the instructions here? https://wiki.archlinux.org/index.php/Disk_cloning#Cloning_an_entire_hard_disk That certainly seems the simplest method, assuming the errors remain manageable. Other methods that might work would be * rsync from the roots of the old partitions to the new ones * full restore from my backups Thanks in advance for any advice. Walt
