I'm interested in knowing if partitioning a drive can put your hard drive under undue wear and tear. I've been partitioning my hard drives ever since I got the original iMac, and I've never had a problem with the hard drives I've used. I actually recommend partitioning because that way you can use one as a repair drive, if needed. But my friend said that it could cause a 30% higher chance of the hard drive failing. (I have no idea from where he got this stat.) If that's true, I might rethink my decision to use partitioning. So is this true, or is the difference negligible?
