Ordered a Swann 8nu DVR & a big Western Digital HDD to put in it . . . The DVR arrived before the HDD, so I pulled the HDD out of an old Clover cdr4070 and put it in the Swann DVR . . .

Used the Swann with the old Clover HDD for a few days until the new HDD arrived . . . After installing the new Western Digital HDD noticed that the Swann now has a much better frame rate on playback than the old Clover HDD . .

So if you are picking up a hard drive to put in your DVR, I think it would be a good idea to get a good quality HDD . . . I have always had good luck with Western Digital hard drives.

Didn't notice what brand the old Clover HDD was, but it was likely some no-name POS.

It shouldn't be that big an issue. Most likely what you saw as a drive who's motor is in the soon to fail stage and you got it early.
