Need Help Cloning a Drive

Well, the saga continues.....
I tried going the MS route....I hooked up a usb drive and created a system
image and a recovery disk from the Windows 7 partition that came with the
laptop. I then booted with the new 750 GB drive using the Windows recovery
disk and restored the image that was save earlier. I then booted into
Windows and that worked! I was thinking I would just re-install Debian and
then copy over my data from the old drive. However, when I booted into a
Knoppix disk and ran gparted, I discovered that Windows had created an image
of the whole drive - Linux and all! However, being Windoze, it failed to
take into account the difference in partition sizes, and force my new shiny
drive to use 512 b sectors! This is what fdisk reveals:
Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x81d6785f
Device Boot Start End Blocks Id System
/dev/sda1 1 5 40131 de Dell Utility
Partition 1 does not start on physical sector boundary.
/dev/sda2 * 6 1918 15360000 7 HPFS/NTFS
/dev/sda3 1918 7017 40963092+ 7 HPFS/NTFS
/dev/sda4 7018 38913 256204620 5 Extended
Partition 4 does not start on physical sector boundary.
/dev/sda5 7018 37615 245778403+ 83 Linux
/dev/sda6 37616 38913 10426153+ 82 Linux swap / Solaris
Partition 6 does not start on physical sector boundary.
Note the sector size line....
So, now I have two problems to solve.
1. How do I "fix" the drive so it uses the same sector size for logical and
physical sectors? I have seen studies that show setting up a drive like this
is very inefficient when it comes to reading the drive.
2. How do I reinstall grub from the Knoppix disk so I have my dual boot back
in operation?
Thanks for all your suggestions!!
