You can use hdparm to quiesce the bus. Your version of hdparm support hotswap, but no guarentees if your kernel does. http://www.redhat.com/archives/fedora-test-list/2004-March/msg01204.html Even if it does work for your kernel, I have to advise against your approach, because hotswap != removable storage. If you have wiggle room in the colo space, give firewire a fair chance. > MonMotha wrote: > > This is mostly useful on RAID arrays though.
