Not running ScanDisk when you install Windows 9x By default, when you run SETUP.EXE to install Windows, the setup program will want to run ScanDisk before it does anything else. And while running ScanDisk might seem like a good idea, sometimes you need to avoid doing so. In particular, installing Windows on a very large hard disk will probably make ScanDisk crash (apparently it doesn't handle multi-hundred-gigabyte drives too well), so you'll probably need to bypass ScanDisk in any case. You can do this by adding the /is switch to the setup command. In other words, instead of just typing "setup" as you normally would, you'd type this instead: setup /is This switch tells setup to bypass ScanDisk, and works on Windows 95, 98, and Me. Note that this switch is just one of the more common switches that Windows 9x's setup program can accept. A complete list of setup's command-line switches is documented in Microsoft Knowledge Base (MSKB) article Q186111, which can be read on the web at: http://support.microsoft.com/kb/186111
