It is not true, if anything you are more prepared for a hardware failure of any sort, because you not only have a backup, you know how to use it, and can apply it when anything goes wrong.
Other than the total time of spin=up, and any bumping jostling, or abuse of a hard drive, other than very bad enviromental conditions, the hard drives for the most part will happily change the data on the platters over and again like (can I say that) million plus times. The heads will wander back and forth for about as long as the motor that spins that platter will last. Or it could die or break down at any moment.
So unless this hard drive reading and writing exceeds the Operating systems own unabated activity :-) by many many times over. unless your drive is unnessisarily spun-up for years longer. unless your drive doing this extra work is suseptable to abuses, there is little that will change for the added activity.
Plus you have the advantages of an OS that is probably cleaner of cruft, probably more reliable, could have less viruses and malware on it :-) and will run like a dream (until it doesnt).
