What exactly would happen if I were to unmount my hard-drive while using Linux? Would I be able to re-mount it? Would the boot sector still work (I'd imagine so.) Would just my personal files be lost, and the core of Linux be remaining?
Don't want to test it out without having some idea of what'll happen...I don't want to have to do a Rescue or a Re-install..
Thanks guys. :-)
Don't quote me on this but it should only be unmounted for that session. Once you reboot or something it should remount, unless you change some configurations. I don't think you can do anything if you unmount your hard drive. I'm pretty sure you would just have to reboot.

Just wanted to add something. Why would you want to do this?Quote:

Ok. Input from anyone else? ::Doesn't feel like try it from one piece of advice...that starts with "Don't quote me."::
Mounting the drive merely makes a partition available to the operating system after the file system has been determined. Unless you re-partition the drive your data is fine. In linux a CD or tape or harddrive (and pretty much everything else) is all the same, its a device and it just has to be mounted to be used by the OS. There are alot of historical reasons for this system, I'm sure google would reveal much.

My guess is your session or will stall if you succeed, or it will say the device is busy,
As long os your harddrive or partitions are in /etc/fstab your box will remount it on boot.
My question too : Why do you wanna do that ?
umount /
umount / device is busy
Is what happens.
One way to handle the device is busy problem is to use umount -l which waits until the device is free and then unmounts it, but that will be when you shutdown in this case.
