Hi,
I am confirming that using the Easeus Disk Copy (2.3) utility, mentioned several times prior in this and other threads, worked great for me to clone a 500GB eSATA DRIVE (Samsung) to a new 1TB eSATA DRIVE (WD Black) (provided the sectors are not hozed up) and you do not try to use the partition copy. The % free went from abt 51% (500GB) --> 27% (1TB).
I have an SA8300HD on the TWC / Mystro / Navigator setup, so not sure about the others.
By design, there is no standard file system on these SA8300 DVR eSATA drives that Windows or Linux can recognize.
The bootable CD performs a sector to sector drive copy. Afterwards, once connected and booted, I believe the SA8300, using its proprietary file format, simply expands the "unused" space and formats the remaining space dynamically as needed. The target drive I used was a clean, never used, never formatted unit - that may be key as well - unsure. If I we to use a former drive, I'd certainly wipe it clean with 0's.
The sector copy requires a long time, so I had to disconnect my external drive before I went to bed (the recording shows defaulted to the internal drive) and then clone it overnight. It took about 8 hrs for the 500GB of sectors it moved via the USB connections.

I also saw postings in other threads and forums that others have used Active@Disk which also has a sector by sector copy feature and the linux guys can use the familiar dd if= of= while booted from a small CD/DVD distro to do a sector by sector.
I do not know if any of these tools are or will be confuse by the new 4K sector drives.
I may try a 1.5 TB WD Black in a few weeks for kicks. I was tempted to try a 2.0TB but it is currently out of stock, so not an option for me.
Rough outline:
Download and burn utility ISO
Hook up both drives up to older laptop using two Roswell eSATA/USB enclosures.
Booted laptop using the Easeus Utility
Select the DRIVE copy
Selected the correct source and target drives.
Let it copy.
When I reattached the new drive to the DVR, I followed the procedure noted here by many others:
Power down SA8300
Unplug Power from SA8300
Connect eSATA, power up drive
Connect Power to SA8300
Allow to boot
Power on
Press "A" when prompted by SA8300 for new drive. In my case with Mystro/Navigator, it did not threaten to wipe the drive, it just wanted you to ack that you had connected a drive.
Review the % Free and make sure shows are still there. If not, force a reboot again and watch for the "Press A".
I will post if I have any issues in the coming weeks.
Later.
