this has probably come up before but is there a way to make your own time capsule for OSX??

or better off just using whatever spare harddrive for timemachine to connect to and backup to

Hello,

As of right now, I am using a Partition on my 500GB Seagate External Hard Drive as a Time Capsule. It works well, and no problems with it. Any external or portable drive will work if you format it to Mac OS X Extended (Journaled).
