Difference between a sfc /scannow and a repair/overlay ins..

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

well, sfc /scannow checks your system for damaged or deleted dll files or
other system files and repairs them, or installs them when they are missing,
and the disk might be needed, or not, but have never heard of a
repair/overlay install. I've heard of a repair install, a clean install,
and an in-place upgrade, but never a repair/overlay install.
A repair install will attempt to repair your copy of windows by deleting
your files, then reinstalling them with the OS disk.

Hello,

Thanks for all input. Your understanding of scf /scannnow and repair
installation is correct.

As to "overlay installation", based on my research, it is called "overlay
installation" when your computer is using hard disk management software
(such as Disk Manager, EZ-Drive, or DrivePro) for hard disk geometry
translation. It is mentioned in the following article.

Hope it helps.

If there is anything unclear, please let me know.

Regards,
