OK... did you partition the new drive first? You'll need to make sure
<br />>
that you do that.

NOTE: Don't just copy and paste this, because if you get it wrong,
<br />>
you'll wipe out your remaining good disk. Make sure you edit to fit
<br />>
your particular installation & needs.

This will copy your partition table on /dev/sda to /dev/sdb:
<br />>
sfdisk -d /dev/sda | sfdisk /dev/sdb
<br />>
<br />>
If your bad disk is /dev/sda and your good one is /dev/sdb, then you'd
<br />>
want to turn that around appropriately. (ie: swap positions of the sda
<br />>
and sdb in the above statement).
<br />>

Again, make sure that you get it right, because I'm just trying to help
<br />>
you with the command syntax here and can't be responsible for its
<br />>
misuse. Nobody, least of all you, wants to see your next post be "Now
<br />>
all my data is gone."
