I recently reformatted a Solid State Drive (labeld D:) in my computer. Previously the SSD had Windows 10 installed, as I was dual booting Windows 10 & 11. I also had Steam games installed to it.

After reformatting, when I try to re-add a Steam library folder to the drive it fails with "Steam library folder is not writable". Currently the drive is empty, so there shouldn't even be a Steam folder to write to.

Why can't I add a Steam library folder to my empty drive?

The issue was caused because the drive had an existing Steam library folder before it was reformatted and assigned the same drive letter (D:). Steam still had the old library path saved and was looking for it on the new blank-drive.

To resolve the issue, I located the old path file C:\Program Files (x86)\Steam\config\libraryfolders.vdf. I then re-created the Steam folder that was being used before the drive was formatted (D:\\Program Files (x86)\\Steam). After restarting Steam, the folder now correctly displays in my Steam Library.

Thanks to KRoman47 for the solution.
