Problem #1: So when I go to the Disk Management tool in Win7, it says I must first "Initialize Disk". It's giving me the option of using a Master Boot Record (MBR) or a GUID Partition Table (GPT) partition style. Which do I choose?
Master Boot Record partition tables are "classic."
You should choose MBR by default, since they are recognized by pretty much all operating systems and utilities.
GUID Partition Tables are somewhat cutting-edge, and only required for disks > 2TB. Many computers won't boot from a drive with a GPT.
Problem #2: Migrating the OS from 2X500 RAID 0 > 240GB SSD
Question #1: Will True Image be able to copy all of the partitions and successfully move them to the 240GB SSD? By successfully, I mean, will the recovery partition still be usable?
When I do a Disk Clone and select the entire disk, True Image copies all partitions, boot sector, and partition table. It may resize partitions to larger or smaller size, depending on the relative sizes of the drives. By default, it makes some choices for you, but gives you advanced options if you need to adjust the partition sizes manually.
Question #2: Also, will there be problems trying to move an image from a 1GB RAID0 setup to a 240GB non-RAID one using True Image?
As other posters have noted, converting RAID to non-RAID could present an issue during boot. I've used True Image on laptops and desktops with many drives and complex partition schemes, and it's always worked well. I have not yet used it to convert RAID to non-RAID.
The only other obvious issue is that the 1TB RAID volume might have more data in it than the SSD can hold. True Image will clone a larger drive to a smaller one so long as the data doesn't exceed the smaller drive's capacity.
Question #3: So I guess I can use the free edition, right?
So long as the RAID configuration doesn't prevent the installer from identifying the drives as WD brand. There's no way to know unless you download it and give it a try. (The installer is about 115MB, as I recall.)
Question #4: Oh, and is True Image one of the only few ones that can do this kind of a transfer?
It's the one I have the most experience with, since I often use WD drives, and they made a free version available. I've been cloning hard drives since 1995 or so using HDCP and Ghost for DOS. True Image isn't the only tool like it, but it has been the most reliable and capable tool I've used on Windows XP, Vista, and 7. I haven't had a need to look elsewhere.
SUMMARY
I suggest you download
Acronis True Image WD Edition and give it a try. The worst case is that it won't work and you'll have to seek another solution. In the process, though, you'll learn a bit about cloning and disk management, which will be useful experience going forward. (At least skim through the user's guide.) You need to get comfortable with this sort of thing if you plan to handle your own upgrades and computer migrations.
Others mentioned aligning partitions. True Image resizes and aligns partitions for efficiency automatically. I'm not sure whether it accounts for the
new alignment issues for Advanced Format drives, but I doubt that your SSD uses Advanced Format (low-level sector size grew from 512 bytes to 4K bytes to accommodate drives > 2TB).
Finally, did Dell give you a set of recovery media on CD/DVD? If so, I would try a fresh install of Windows onto your SSD using those disks. Once Windows is installed, you should be able to boot from either the RAID or the SSD by switching the boot order in your BIOS or pressing the hotkey for a boot menu.
This task could be fairly complicated due to the RAID setup. Ideally you should disconnect both RAID disks so the only disk the computer sees is the SSD, to avoid any chance of installing on the wrong drive or erasing your data. I'm not sure how your BIOS will react when both drives are disconnected.
It sounds like a fun project, though, and a good learning opportunity.
If you have another PC or an external hard disk, I strongly encourage you to begin by copying any files you can't easily replace to that other storage - photos, documents you've created, etc. Also, visit Dell's web site and download the latest drivers for your computer / operating system and put them on a flash drive or external hard drive, so you can easily reinstall them.
Good luck!
