The adapter works flawlessly, perfectly and without problems !! But I can not use him. What I am disappointed is: an IDE hard drive is standardized. So the connections are the same for all IDE drives, so you can each build in the notebook without having to be afraid that the connectors are twisted and does not fit the plate. In S-ATA disks which is also well standardized so. worldwide. The adapter fits perfectly on the S-ATA drive and is also aligned nicely. But the IDE port is now not at the point where it would now be at a IDE disk, but so that the plate if you have it infects below air, and exactly by that distance then of course projects. So the problem is not because of the size, but because of the connection offset (rotated) is. From the length and width and height, it would fit. I have done some handicrafts at the housing, also tried umzuplatzieren the motherboard something (going in tight Notebook housing but only minimally). The "useless" Jumper (which was already described by others) was removed from me, and I have the two pins clipped the then protrude yet, so I won a place for my experiments. Therefore, the adapter works fine, but I can now, of course, this is no longer return. So this adapter will buy only if it is NOT installed on a "normal" notebook for plates. I have the adapter in two Acer and IBM tried as mentioned works, but is exactly reversed.
