I've never done it, but I have read that it is possible to use

It might be more satisfactory to spend some more cash on a twin to your
new drive.


Return address scrambled. Replace nkbob with bobkn.

To give an example, if you tried RAID1, using a 40GB and a 320GB drive,
the resulting mirrored array has a capacity of 40GB, and 280GB on the
second drive is inaccessible. Given the low price of drives, buying two
new ones ro make a RAID1, makes more sense.

Thanks, This might work if I can remove the smaller drive later and use it
as a recovered drive.
My main problem is that I can not copy all of drive A: (the smaller, older
drive) to the newer drive. (it's larger) Windows crashs while copying it and
so does the Seagate utility that came with the drive.
I was hoping the Raid function might work around it by copying everything to
the new drive as a back up and then installing the new drive in place of the
older drive.

Think it will work?
