Generally, yes. Linux installers also require you to partition drives manually. However, the interface is different. You must select "Something else" or "Manual partitioning" to ensure you only format the target drive. If you select "Erase disk and install Linux" with multiple drives connected, it may sometimes target the wrong drive depending on the distro. The "Physical Disconnect" method (Phase 1 above) is highly recommended for Linux beginners.
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.
If your goal is to wipe only your primary C: drive and leave your secondary storage drives alone, follow this procedure.
Physically disconnect secondary drives. If you are not comfortable identifying drives by their size or model number in a list, the safest method is to: does clean install wipe all drives exclusive
Many users confuse "clean install" with "low-level format" or "zero-fill wipe."
| Action | Wipes Drive C? | Wipes Drive D? | Wipes External Drives? | | :--- | :--- | :--- | :--- | | Clean Install (Windows) | Yes (Target partition) | No | No (unless unplugged) | | Diskpart Clean | Yes (Entire physical disk) | Yes (if same disk) | Yes (if connected) | | Factory Reset (OEM) | Yes | Possibly | Possibly | | DBAN (Darik's Boot and Nuke) | Yes | Yes | Yes (everything) |
The exclusive nuance: If your Drive D is a partition on the same physical hard drive as Drive C (e.g., a 1TB drive split into C: 500GB and D: 500GB), then a clean install using the "Delete partition" function will wipe both C and D because they are on the same physical disk. Generally, yes
If Drive D is a separate physical SSD (different hardware), a clean install will never wipe it unless you manually click on it and press delete.
To answer your query definitively (and exclusively):
The Short Answer: No. Not exclusively. But the confusion is understandable, and getting this wrong can cost you your entire digital life. You must select "Something else" or "Manual partitioning"
When you hear the term "clean install" of Windows (or any operating system), the immediate fear is that you are about to nuke every photo, document, and game from every hard drive connected to your PC. However, the reality is much more nuanced.
In this exclusive deep-dive, we will separate fact from fiction. We will explain exactly what a clean install targets, which drives are safe, which are at risk, and how to perform a true "full wipe" if that is your goal.
If you have only one physical drive (e.g., one 1TB SSD) but split it into multiple partitions (C: for Windows, D: for data), a clean install that deletes all partitions will wipe the entire physical drive — including your D: data partition.
