Never formatted my home rig: OSR2. I have gotten new HD's a couple times, and always just swept the old contents onto the new HD. I've upgraded the motherboard several times, and always managed to get everything smoothed out without needing to format.
The reason I do not like to format is because I would lose all the tweaks to my system and to my programs, plus you would lose all your email archives (unless you back them up to CD or something). I mean, like all your bookmarks, your game configurations, registry tweaks...all of this would be wiped out in a reformat, unless you back it up to CD. But then again, if the person backs up registry tweaks to CD, isn't that kind of defeating the purpose of the reformat?
I keep an extra copy of my Windows directory in case anything goes horribly wrong. This has saved me on numerous occasions. Just rename the directory, and you are back in business where you were a month ago or so.
Seems to me there would be two reasons folk would format:
- The person enjoys tinkering with the PC because it is his hobby (kind of like taking apart your car and reassembling it). In this case there is no real point to it, other than that the person enjoys the hobby, which is fair enough.
- or, the person reformats because it is a relatively easy way to resolve conflicts, such as when upgrading an OS, or upgrading a motherboard or HD. In this case, reformatting is kind of like a clumsy brutal way to solve the problem (like leveling your house to fix a leaky roof), and if the person had more savvy and more patience, he could get everything working fine without needing to reformat.
