I purchase a LaCie d2 extreme triple, external hard drive, the other day. I would like to be able to read and write to the drive from one XP machine. I would also like to keep it formatted for my Mac, for ease of of use on my end and to keep it boot-able. Does anyone have any experience with MacDrive? The person in charge of the PC said I could install it if I was "confident about it's peaceful coexistence." Will it be obtrusive to others using the PC? Any other alternatives?
