I have a Sci Atlanta 8300hd with an external sata drive connected (500mb). Although the drive can be disconnected and reconnected no problem, you cannot connect it to a different dvr.

I want to upgrade to a 1.5tb drive, however, my 500mb is still half full. I was planning on removing the 500mb, recording shows to the 1.5tb during the week, then reconnecting the 500mb on the weekend to finish watching what's on it.

Question is, will my DVR continue to recognize the programs on the 500 after I attached and unattach the 1.5 or will it ask me to reformat the drive?
