I am planning to reinstall windows on my computer (clean install, meaning formatting the disk).
I already have 2 partitions, C: and D:, and I already have my important stuff in D: (the same physical hard drive).
My Windows 7 license is an upgrade, not a full, therefore, I will not format C: first and then install Windows, but let the installation disc do the formatting and install.
When reinstalling Windows in C: with a clean install (formatting), is there ANY risk on deleting stuff on the D: partition, or is it perfectly safe?
Note that of course I do know that there are always risks and I should have another backup elsewhere of my stuff in D, but let's assume physical damage is not an issue. Is there still any software-related issue in the formatting process that may delete D:?
The whole point is that I want to fresh install windows 7 and I don't want to wait long for a complete D: backup, so should I just do it with no worries?
