Hello all, I am thinking of buying a 2 TB WD My Passport Ultra External Hard drive and I'll be using it with both OS X and Windows. I am planning to use this drive for my Time Machine data backup after creating additional partitions in the external HD. I will also be storing a large number of files of Music, Videos, VMs(>4GB) and software setups. I know the limitations of Fat32 that it can't be used to copy files that are greater than 4 GB and of exFAT that it is prone to data corruption and chkdsk errors. I am confused on how many partitions should I make and what should be the formatting scheme on each partition? Also I want to know how much space should I leave on external HD for Time Machine Backup? I'll be backing up data only after a month or two, and my MacBook Pro has 256 GB SSD out of which around 220 GB is in use. Any help/opinions would be appreciated.
