Your best bet would be to jumper pins 7-8 and then in the XP reinstallation, delete and recreate the partition you’re installing to.
If you’re using more than 1 partition, you’re going to need to either create the partitions in your current version of XP and then run one of the alignment tools on them or you can just let it install “slow” and then run the alignment tools on them on the new install of XP.
I’d recommend the former personally. As always back up your data.
Newer linux live cd’s made for partitioning can do it as well, but you need to be sure you know what you’re doing.
You can go to the downloads page for your drive and use WD Align utility to align the partition with XP installed. That’s if you have just one partition, though. Also, remember to back up important data before doing that.
You can use it for more than 1 partition too. I know there was another post about someone having inordinate amounts of free space before and after partitions after aligning them. Would explain why if the utilities are only meant to handle one partition on a drive.
Here, look at this link, and see if that helps answer your question. We actually put out a couple of different kinds of utilities to help in this. I’m not sure, anymore, which do what.
