So you can recycle a slot which is much smaller than a hard drive.
Remember that recycling is all or none. So if you make the volume the
entire size of a hard drive to recycle you have to recycle every job
stored on the hard drive.  At home I use a virtual autochanger with 40
5GB slots and 2 magazines with each magazine being on a different hard
disk (one external one internal). At work I use a tape autochanger.
But at work I have 180 tapes and 50TB+ to store in my backups..
