I've searched here, and Google (microjogs, microjogs hard drive), and I've seen many posts on how you need to match "microjogs" when doing head swap, but I can't find where you're supposed to find this info. The label? Via Deepspar or PC3000? Looking for a WD donor (know where to search) but I need this info and I'll be damned if any Google search of "microjogs" doesn't point to a Portuguese flash gaming site.

Thanks.
