I purchased a larger hard drive (~750 GB)) for my laptop and want to clone my current laptop drive (~320 GB) to the new one. The new drive is connected to the laptop via usb - I can mount it and read/write to it. This is what I did, but it didn&#39;t seem to work out...<br>
<br>1. Boot laptop using latest Knoppix<br>2. umount both /dev/sda(old drive, internal to laptop) and /dev/sdb (new drive connected via usb)<br>3. I was going to use dd, but read that dd_rescue is a little better (read error handling, reporting progress), so I installed that and fired it iup <br>
<br><span style="font-family: courier new,monospace;">knoppix@Microknoppix:~$ sudo ddrescue -f -n /dev/sda /dev/sdb</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;">

<span style="font-family: courier new,monospace;">Finished       </span>            <br><br>4. I thought, time to use gparted to expand the Linux partition for my new drive to the full size, and install the new drive.....but wait, there are problems!<br>

I am not sure what the warnings are for sda, but it looks like dd_rescue did what it was supposed to do. However, What do I do about the errors on sdb? GParted does not recognize the partition table for sdb, and reports 698 GB of unallocated space.<br>
<br>Thanks for any suggestions you may have to solve/explain what is going on!<br><br>Mark<br>
