I run a total of 76 mods for skryim, and have been able to use old rim mods on skryim vr with out porting. I Have never had an issue, certainly not one that wipes a hard drive. (I aslo have a master back up on a ssd external just incase.) Same for Fo4 - no issues. %90 of the mods are from here but a few are from an external site. I have to agree with hey you's reply. FNIS Behaviors can cause issue if not used correctly, or mods that write over existing files. Sounds like a hardware problem. Hard to know with out more info. like what mods you are running, and what hardware you are using. my old machine i was running a GTX 1070 and it ran with no issues. And if its wiping windows, a mod wont do that. Side note, if you cut the power or hard reset while a hdd or ssd is writing it can wipe and possibly corrupt the drive. ( During updates, saving or transferring etc.) And if you dont already no this, if your running mods on skyrim you should be launching with sse launcher not the main skyrim launcher, this will cause issues as well.
