Simple tool to copy large amount of files

[Dreaming]

Hiya.

Getting two new hard drives on monday, both 160gb 16mb cache for fast raid0 performance.

Atm I have 2 250gb just in there, no raid.

So, it's going to go like this:

1. Put in the 2 new hard drives for raid. [lets call it array1]
2. Create partitions on the array1.
3. copy data (roughly 200gb worth) to array1
4. set up data hard drives in raid array [lets call it array2] (not sure whether 0 or JBOD is better really for data, but got annoyed at having two partitions and not having enough space in my movies bit, but having 30gigs free in my games bit. So gonna clump it all together)
5. copy data from array1 to array2, array2 being partitioned as one big thing in NTFS to make it Vista friendly (it's not too keen on Fat32)
6. repartition array1, install OS/es (not sure whether I cba to dual boot yet, haven't used XP for donkeys now!)

so yea, that's it in a nutshell. But wondering, aroud step 5, am I going to need to install a small OS *Just* for copying data, because after the data has moved off array1, then I will repartition it depending on my OS needs :-).

Will end up with:
Array1 (raid0) - 2 x 160gb raid edition hdd with OS/s and program files on
Array2 (raid0 / jbod - need the storage too much for raid1) - 2 x 250gb hdd 1/2 full with data

I bet I could do it with a linux live cd, but they seem really fiddly, as you have to mount drives before you can use them and everything. If there was some small app I could run from a usb stick / cd that was a command line thing, and basically copied all data from one partition to another, without the need for an OS being installed, that would be much better. Linux blows .

Finally, the annoying issue, is that I want to fiddle with the controllers a bit. So, data might have to go from:

data hdd -> new hard drive(s)
set up old hard drives on the slower controller
copy data over
set up new hard drives on the faster controller

Only thing I'm a bit miffed about, is in theory the 2 x 250 will be faster, but I need the storage space, and you can't win everything! It should still be pretty fast.

p.s. it's an Asus P5W DH motherboard, with the following raid controllers:

Asus EZ-Raid (onboard implementation, requires no drivers, but apparently a bit slower)
Intel ICH7R (faster than the Asus, has 3 sata ports rather than the two, but requires drivers)
JMicron JMB363 (can't really be used, it has one sata port on the motherboard, then an e-sata port on the I/O shield to backup your data to an external hard drive easily

atm, the 2 hard drives are using ports on the Intel one.

use a WinPE CD

robocopy is pretty good for data moves.
