Hard drives are hard drives...no matter if they come from a DVR. All you need to do to use them in a computer is to reformat the thing (it takes the little programs off of it that the DVR uses and makes it function on a PC.



NOW that being said...you have IDE hard drives....not worth much and probably not long before they crap out (hard drives have a shelf life based on number of hours used (they have mechanical parts that wear out). Not sure how much they are worth, but Ebay will tell you....MAKE SURE TO MARK pulled from machine, reformatted and worked at that time NO WARRANTY. If you see bad sectors come up when formatting, scrap it....about to crap out. Otherwise, sell as is with no returns or warranty listed in the ad. Rest, scrap away.

When you start pulling from the newer DVR's, SELL those working ones like you STOLE them....worth far most than scrap.
