| you could set up mdadm, RAID1 the drives, add new drive, sync, remove old drive, then expand sizes. I've done this before, but I also use LVM which makes it a bit easier... |

IMHO, I would start from scratch, it can save headaches later, but you can also wait for more replies  |

Boot a live cd/usb, with both disks connected. Partition the new disk and create the filesystems.
For each partition (e.g. you may have a seperate /home or /usr or whatever) mount the old and new targets (e.g. the old and new / partitions) and "cp -a" or "rsync -a" the files from the old disk to the new one.
Fix the uuid's in the new /etc/fstab so they have the new values (you can "ls -l /dev/disk/by-uuid" to see them). umount the old systems disks and follow the manual guide to chroot and re-install grub to/from the new disk.
Hopefully I've remembered everything  |

Thank you guys, but will any of these methods copy MBR?
See, I have legacy GRUB in MBR, and GRUB2 in the aptosid root partition.
Otherwise, bfree method will be the solution and dig out a sidux live cd for legacy GRUB
Also, I feel nowdays harddisks are big disappointment and WD doesn't carry the enterprise line anymore(or they've hidden from me). What brand/model are you satisfied with?
In order of importance: Reliability > Speed > Noise |

Is there a special reason you are using legacy grub in MBR ?
To backup the MBR you can use
sfdisk or dd |
