Formatting HDD after fresh install of windows on SSD

[mojeer.ghaghechi]

I'm going to fresh install windows 10 on an ssd, however after that's done, does the partioned C: of my old hdd stay as a partion of merge with the other main partion of the hdd. Are there any files lost from hdd after I plug it in with OS on ssd because I don't have another hdd or external to move my files from hdd to format it before the fresh install.

No. Nothing will be lost after you connect the old HDD. But set the boot priority to the SSD on boot menu else you might endup booting from HDD.

Peace.
