My sister got one crucial p3 as well. Along with a new motherbaord, ram and cpu for an upgrade. Haven't had the time to set things up for her but I'd like to see if it works with her new components.
(I have been testing that second crucial drive as well, same issues).
If it works in her setup then she can take both the drives, if it doesn't work then I'll just ask my brother in law to return both of them.
Kind of afraid that it will work on her set up, if it does that'll mean there's something wrong with my system right?
