Modern USB software hosts and USB mass storage class have a mechanism to handle the surprise disconnect without unmounting USB drives first. This hassle has ended with Windows XP. Otherwise billions of users would have really bad USB experiences. | |

I would for sure mount/unmount in software, I wasn't trying to emulate a forced-removal situation... Just wanted to have the device sit plugged in, but be otherwise unmountable/detectable in software. | |

It does not solve the problem of stopping communication on the device before the power is shut down. If you pull the power during a read or write operation, you may corrupt the memory, thats why you unmount first, to stop the software from talking (and to sleep the device sometimes) | |
