You don't change jumpers anymore. That went out with IDE drives, none of which ever reached TB capacity to the best of my knowledge, so you're clearly using SATA drives. Which brings up an important question that must be answered before you can proceed any further: Do you know how to install XP on a SATA drive?
I have an 8 year old computer running XP. Three years ago I installed 2 1T hard drives and left the old one connected as a backup. The old one has now finally failed and my c: drive is acting funny ...suspect it is sick too. I would like to change my currently lightly used 1T drive into my c: drive and use the current ailing one as a backup until it completely dies. How do I do this? I assume it involves reinstalling XP but at what point do I also change the jumpers? I don't want to lock myself out of my own computer. I hope that is enough information. Thanks for any help.
