[X-Newbies] how to seamlessly use added hard drive

[Chris Beamis]

It's a Seagate, and I tried putting it on the end of the line with  
jumpers at Master, but no joy, so I set it back to Cable Select.   
What finally worked was to boot off the new big drive with it in the  
middle position and the other drive not installed, set boot drive to  
CD, open CD drive and insert install CD, boot off the CD and set boot  
drive to the big drive, reboot.  First tried running with only the  
new big drive on the end of the line, and now I'm running off the new  
big one at the end of the line and the old small soon to be wiped one  
in the middle position.

Thanks for all the help to everyone.

I'm going to look it up but just in case anyone would like to  
contribute any free advice :), any recommendations for securely  
wiping the old disk, with ones, zeros, randoms, repeatedly?

Thanks  again,
Chris
