There are several possibilities I can imagine. - lots of raid or jbod devices allow hot plug/unplug capability for HD - USB or firewire external drives - external network attached storage - iomega makes a fairly new alternative to their "zip" drives called a "rev" drive using 35GB capacity cartridges - iomega again, for their "rev" cartridges makes a 10 slot auto-loader that would almost make it like a tape changer An aside, which won't tell you linux guru's anything new, but which I recently found out. Under RH at least, you can label an external drive with a unique identifier. The /etc/fstab file can use that identifier rather than a device path. Each of several external devices/drives can have their own unique mount point. Whenever you plug in one of the drives, no matter which port you plug it into, it will be mounted on the same directory you have chosen. I can envision a setup where a virtual changer, using external drives, has a top level directory with subdirs labeled "slot-1", "slot-2", ... And whichever or as many external drives as you have plugged in, they always get mounted back to the same slot you originally specified. Kinda like barcodes :) -- Jon H.
