This is probably a simple question, but I've only recently switched from win98 to XP. I have a freshly formatted hard drive as a slave (drive E:\) and want to use XCOPY to copy everything to the extra drive. I want to keep it as a backup in case something happens to the C:/ drive. I'm using the commands xcopy C:\*.* /h/e/i/k in the ms-dos command function and it works great until it hits a file that is in use by XP. This tells me I have to boot up to the dos prompt so that it can copy all the hidden and system files. Any reason why that wouldn't work if I could figure out how to boot up to the C:\ prompt?
