Smartd has reported that I have 7 uncorrectable
errors and it appears to be located in my swap
partition. Zeroing out the swap partition and
mkswap, failed to correct it. So it seems that
the drive after less than 1 year has gone bad.
Looks like I will have to RMA the drive as
it is still under a 5yr. warrantee.
So, I bought a new drive and used gparted to
copy over all the partitions sans the swap
partition from the bad drive over to the new
drive. Everything is now copied over but I am
still in doubt of the new drive's MBR sector.
Question: using gparted, does it also include
the boot sector MBR when copying over the
first partition or do I have manually copy the
boot sector over or to apply the grub-install?
If so, what is the best way to ensure that the
MBR is on the new drive?

I didn't realize gparted could copy partitions from one drive to another
but the MBR is not in any partition but rather the first 446 bytes of
the 512 bytes reserved in the boot blocks
The best way is to have installer DVD/USB and boot into rescue mode,
chroot to /mnt/sysimage and then simply run 'grub-install /dev/sda'
Craig
Yes, gparted can do that; copy partitions from drive to drive. Very. very
handy program, especially when it exists on a LiveCD so that you can
work with unmounted filesystems. I use the Ubunto LiveCD to do this
as it does not exist on Fedora's LiveCD, but no big deal I think. The nice
thing is that it allows you to resize/move partitions around while you are
reorganizing a new drive.
Question: Could I simply use dd to copy over the MBR from drive to drive
or is it too risky?
----
personally, I think it is too risky but it's your setup...
dd if=/dev/sdX of=/dev/sdY bs=446 count=1
You asked what is the best way, I answered but apparently you don't like
best way answers.
Craig
No... it's not that I don't like "your" 'best way answers',
as it appears either way works (grub-install &| dd). What
I like about the dd-way is the ability to do backups but
what the heck, maybe that is not even needed. ;)
