said by spudmanmike:What i'm worried about is when I plug the 400GB drive into the PC (or Mac), it could write some hidden files to it and render the drive corrupted to the DVR. Do you think the SA is picky with the drive..?? With how flawless and uncomplicated its install was, I wouldn't think so..
The external HDD is matched to the STB it was formated on. Files on this HDD will not be able to be used on another STB.
When you connect the dupe HDD (If your able to get it copied from the original) it will force you to reformat it, as the STB ID code will not match.
This is required by DRM.
