here is what I would do.

setup zoneminder and mysql on a small 80gb or less
do not start zm or mysql

now your 1tb drive format as one big partition.

mount the drive under /storage
now create 2 folders /storage/mysql and /storage/events

copy the /var/lib/mysql to the /storage/mysql
same goes for zm events folder copy /var/lib/zm/events /storage/events

now sym link you /var/lib/mysql to /storage/mysql
and /var/lib/zm/events to /storage/events

turn mysql on check for errors
make sure you still have zm off and there are no events
setup your cameras.
now go into filters and in the "purge when full" filter instead of deleting have it send you a email at say 90%

Now turn off mysql and unmount the partition.

Now install partimage and make a image of the 1tb drive.

now remove 1tb drive insert new 1tb drive
next use partimage to restore the image you took

repeat last 3 steps for more drives.

Now when you get the full drive email.
Shutdown remove 1tb drive insert one of the formatted ones.
And your ready to go.

and when the drives need to be reused just restore the image file to them.

Now the trick to reading them back.

2 solutions

get a pc to view.

or

On the same zm server install Sun virtualbox (not the OpenSourse version).

make a copy of the 80g drive and use that as the image in Sun virtualbox

next go buy a usb to sata adaptor.
now setup the sun vm to always use that usb adaptor.

so when you need the old eventsplug in the usb drive.
and start the virtual machine
