I have 2 of these 2.5-inch hard drives. One for Mac and one for Windows. Plug it to format, and split if necessary 2 Tbyte into several smaller partitions, that was it. For the Mac I have a Mac partition (read-only for Mac) and a partition both readable by Mac and Windows. The Mumbi disk bag I bought with fits perfectly with the hard drive. The value for money in my opinion is completely ok.
