I have two usb external hard disk and I want to know if I can merge them as it had one hard disk and thus the SO see them as one hard disk.

Are there tools to do that or can I do with Windows builtin tool?

Thanks but I don't want to buy an enclosure! Is there a software solution? – xdevel2000 Sep 13 '10 at 17:55
I'd strongly advise against doing a software RAID on external drives especially. You then have 2 points of failure. – John T Sep 13 '10 at 18:02
-1 ??? why? I think it's a good question! There is really no reason to have a -1... – xdevel2000 Sep 13 '10 at 20:41

Windows built-in diskmgmt.msc does only support merging partitions from the same physical hard drive.

The only way to achieve that using only out-of-the-box software would be to use diskmgmt.msc to mount your drives as folders in your system drive.
