Hi, Just finally migrated to Mac from using Customized PC for years. Fact that is I had 2 HDDs ( 2TB NTFS, and 500GB NTFS storage with tons of personal data) that I want to reuse as a storage, since I have 512GB Flash on my nMP only. I would like to know what I can do to simply just plug in this two NTFS drives and continue to use it as an external without formatting it. Options that I know so far but not sure whether or not I have to format are: NAS, and External RAID. Can anybody clarify the concept on how to deal with this transition?
