i am getting my new macbook and first time mac user. I need to use xp once a while for softwares such as matlab, sas, etc, so i decided to get the parrallels. my understanding is that parallels creates a virual drive, and you can store ur data outside of that virual drive(same drive where the mac os is), but my question is: what if ur mac os went wrong one day? you still loss your data, right? is there a way to create a 2nd partition where u keep ur data from both xp and mac os, this way, you still have u data regardless which system went wrong. I always have at least two partitions when i use my ibm laptop, so in case my xp crashes, i can always retrieve my data. your inputs are appreciated. thanks.
