Hi Leonard, Thanks for your response and advice.

You should use >two disks on separate controllers. I am aware of hardware RAID on M$Win OS using a controller connecting to 2 hard discs. But I am interested to learn whether Linux offers software controller to connect 2 hard discs. If "Yes" then how to make connection to 2 discs ? One to Primary IDE another to Secondary IDE, both as master ? Or to the same IDE, one as master another as slave ? Could you shed me some light ? Thanks in advance. B.R.
