Thank you. 1 - back up your data 2 - convert to hw raid 3 - test carefully to be sure it works 4 - reload your data And left out, step zero, consider why you want to do this if what you have is working reliably also, between 2 and 3 consider upgrading to a distribution and kernel written this millenium. Given the state of hardware raid when that kernel was new, and the state of the drivers, I would be very sure I had a GOOD reason to change anything. -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979
