Normally when we disconnect a USB flash drive, we have to right-click the lower right corner of the taskbar and remove hardware. Is there a way to do it with DOS commands instead?

It should be possible, search for rundll32.

Left-clicking is already very convenient...

devcon ........ I looked it up online, seems like it has very powerful features. [ Last edited by WANKOILZ on 2008-5-29 at 11:04 PM ]

@echo off for /f %%i in ('devcon findall usb* ^\|find /i "usb mass storage"') do devcon remove "@%%i" devcon rescan This deletes the installed USB drivers. How can I make it only disable them?

Just try: devcon remove @usb\* . But first you need to download devcon.exe into system32

The partition command built into XP can unmount it.
