On my 64 bit Windows 7 desktop, I used to have two Western Digital 500 GB drives, each with one partition (C: and D: respectively). But recently those two drives both started failing their self-tests; so I am replacing them with two 1 TB drives. So then I'll have two partitions, C: and D:, each of which is 1 TB in size. Would you recommend splitting each drive into two or more partitions (so I would end up with at least four partitions total)? Or is a 500 GB partition for C: considered rather small with the advent of ever larger Microsoft bloatware? I guess in general I don't know what the pros and cons are for having more or fewer partitions.
