how to clone failing disk in RAID 0 array

One of the disks in my hardware RAID 0 system drive array is failing, but it's still booting for the moment. Is there any tool I can use to clone just the failing physical disk to another identical one?

Typical drive image software will not work for this because Windows sees the two disks in the RAID 0 array as a single volume.
What I need to do is basically mirror the failing disk exactly onto the replacement. I just can't find a tool that will do this -- all my searching keeps turning up drive image tools that run under windows and will happily clone the *entire* drive, but not just the one failing disk.
Because it is a large drive (each one is 500 MB -- I know, I know; I was going to move to RAID 5 shortly, and just hadn't had the time :/) I would like to avoid having to go out and get a 1TB drive to clone the entire disk, not just for expense but because I am afraid that the amount of time it will take to clone everything will increase the chances the disk will die for good somewhere in there.
