So my 750 gig finally came in. I got tired of waiting for NCIX (2 mos) and ordered from a shop in the US. It was about the same price, but got here in a week.
I then followed up with the idea of sector copying my old drive so I wouldn't lose any stuff on my old drive. I discovered that in order for my computer system to recognise the drive, I had to turn off any large block access and other "speed" options for the drive, rather than leaving things in default or auto. The duplication then worked like a charm, but with one major issue. The partition size on the new drive was duplicated as well. Due to the type of file system, I could not resize the partition in the duplication effort, regardless of which program I tried. I even tried Acronis, which is one of the most powerful programs I'm aware of. No luck.
So after all that effort, I to just ended up with a new clean drive with tons of space. I also had an issue with frequent reboots initially. I decided to reformat the drive a second time and bingo, all problems seem to have disappeared.
As an aside, I actually had another hicup. When I put the drive in my machine, it went to the perpetual reboot... blue lights and nothing else. I popped in my old drive and same thing. I had been having some occasional weird problems with it before the upgrade, so after some time with *Choice support, we determined it had just died a regular death as so many others have.
I have a second 530, so I popped the new drive in there, and all is well.
By the way, the place I got the drive (the special PVR model) is ComputerHq.
Good luck to all who plan to do this upgrade.
Good luck to all
