I have a western digital 1 TB har drive 3.5 in and I have the drive trays that were advertised as 3.5 in ones. The tray does not fit around the drive though it seems about half an inch short, don't know why they don't fit because I specifically searched and checked for 3.5 in, anyone know anything? Also the screws don't match on the drives screws location so I know that I'm doing it right. Thanks
