I have a dishnetwork model 626 with hard disk of 120 gigabytes?

And I have a hd of 40 gb inside my pc. Can I change the hd of 120gb form the dish to my pc and vice-versa? after the change , will work well the two devices again?|||Not a good idea, the hard disk in your computer and the one in the DVR are physicaly the same but the one in the DVR is formatted diffrently so if you tried to put it in your computer you wouldent be able to use it without re-installing windows after formatting it and if you stuck the one from your computer into your DVR it wouldent know what to do with it due to the fact that it has diffrent applications on it that it hasnt seen befor. That and you would be voiding you warrenty in like 40 diffrent ways.
