Short answer: No — a clean install typically only formats or overwrites the drive/partition you choose, not every drive attached to the system. However, whether other drives are affected depends on the installer, your actions, and the operating system. Read the rest for specifics and safe procedures.

Power users often run scripts or use tools like diskpart to automate clean installs. A common script is: clean all (applied to disk 0) If the user does not properly check which disk is which, or if their second drive auto-assigns to Disk 0, the script wipes both drives.
