Right, so this isn't complicated, just time consuming.
Before you do any moving of anything, I strongly suggest plugging in your new SSD and booting your current win7 OS, and let windows New Hardware Wizard install the drivers for the new SSD. Will take less than 5 minutes and can save serious headaches in the process if anything goes silly later on.
Which disk backup and recovery program are you planning to use?
I personally use Acronis products, for your needs, Acronis True Image Home 2012,
http://www.acronis.com/homecomputing/pr ... jKccj67F9Q but there are free products that will also work.
My suggestion is to create a virtual image of your current OS drive
You can also create a Virtual machine out of your current OS installation and keep it as a backup.
VMWare option:
VMware vCenter Converter, Convert Physical Machines to Virtual Machines
ONce converted to a VMWare virtual machine you have options as to which software you use, VMWare, Virtual Box, MS Virtual Machine, etc.
Best free backup software. Hard drive backup and recovery, image and clone freeware - EaseUS Todo Backup Free is a free backup utility that will work. The paid version is much better. I prefer Acronis products as I mentioned above.
1. Defrag your 1.5TB HDD that will be used as backup.
You should grab mydefrag.com defrag utility
Download and install if you do not have a commercial product. When installing it, do custom installation, do not add daily or monthly defrag Tasks, do not install the screensaver. When installed, run mydefrag and run a "Data Disk Monthly" defrag on your 1.5TB HDD.
2. Use mydefrag on each disk you need to backup, data disks use Data Disk monthly.
This is the controversial part, you CAN OPTIONALLY defrag your SSD with the System Disk Monthly, it will remove the spaces between files, allowing Acronis, Norton Ghost, and EaseUS ToDo Workstation to shrink the partition size and speed up the backup and recovery.
There are plenty of other programs that will defrag and compress your data , if you have as many 3dSMax files as you've posted in the past.
3. Install Acronis, EaseUS todo free, or VMWare Converter.
Each solution has specific steps, let us know which way you prfer to go.
Acronis lets you mount the backup image file in WIndows Explorer and you can then move files from the backup to your new OS installation.
EaseUS Free does NOT allow this.
EaseUS paid Workstation version does allow this.
A Virtual Machine would allow you to create a shared directory between your new OS and your OLd virtualized OS, start new OS, then Boot your old OS installation, and copy files from the VM Old OS to the shared directory in the new OS, where you can then transfer it to the correct directory in your new OS.
