unplugging devices safely?

[Trent Lloyd]

Hi,

What you need to do is unmount the volumes, if there are file handles
(write ones, read ones don't matter as much i think) then it won't
unmount the filesystem,hence the modules won't unload and it'l think its
still there (and thats all bad)

So always unmount your volumes and wait for it to finish syncing then
pull it out and itl be fine.

Cheers,
Trent
