Google is probably your best friend. Try searches for disk copy, backup etc. Many of the new harddrives will have some kind of software that can be used to copy the contents of the bad drive to the new drive. Maxblast is probably one of the simplest to use. IIRC it boots from a floppy, has a semi grapical interface which allows for partioning and formatting the new drive and then making a copy of the old. BTW many of the purchase products have a limited free trial. As previously posted, set up the new drive, lets sau as master, (if you have two controllers on the mb) set the other as master on the second controller, fire up the software and go. The new drive will be bootable and you can then trash the old one. Pretty sure that IBM drives had a similar utility, not sure if Hitachi stills has the same one. Don't sweat the thing, its really simple.
