The 160GB and 250GB SATA hard-drives I bought from MDT are labelled "MDT re-certified" drives. In fact, they are Western Digital WD1600JS and WD2500JS, re-flashed with a new code and showing a new manufacturing date sticker; one of the 250GB failed during format and reverted to "WD" code. I believe that MDT re-manufacture drives e.g. WD drives; calling these "re-certified" drives "white-box drives" is somehow mis-leading. Hope this helps
