Thread: hot gluing sata cable

didnt work, ill try the power cable next but maybe WD "green" drives just suck.
haha
damn its annoying too.

Are you mounting the hard drives on its thin side and calling them vertical platters?

To the original poster, hot glue works great.
Only apply the glue to the cable tips, then quickly insert them. That way, when removed, most of the glue sticks to the SATA cable itself, and not so much on the hard drive.

1Tb, drives are only available because of "perpendicular recording". Basically vertical instead of horizontal recording. But ~400Gb is where it gets hairy with standard recording. Remeber how hard drive size took a while at 320Gb and 400Gb, then some 500Gb but they were really really expensive? Well that is because they needed to be perfect to work. With perpendicular recording it just like making a smaller capacity standard drive. More densely packed data means every little bump can wipe out a total sector instead of just part of 1 meaning it is less reliable.

From this article: http://www.technologyevangelist.com/...chmark_th.html

Before we try to answer that question let us look at perpendicular recording to understand how this latest improvement works. The recording basics really have not changed since the beginning. Magnetic spots are created on a rotating disk surface that can be detected by a magnetic pick-up known as a read head. The spots are actually oblong on the surface of the disk along the direction of travel. The read head senses the magnetic field of the spot and identifies it as either a digital 0 or 1 depending upon the direction of the magnetic field. Over time ways were found to make the spots smaller and smaller and tracks closer and closer until it appeared that no further improvement could be made.



Looking at the illustration above, the dark arrows represent the magnetic spot son the disk looking at a cross section of the disk, with the pick-up sitting above the disk detecting the magnetic fields as the disk rotates. The practical density limit of this approach was reached about 2 years ago. What to do? Well it turns out that a Japanese professor; Professor Sun-ichi Iwasaki in 1975 came up with the idea of creating vertical magnetic spots instead of horizontal spots. Sounds easy but it required a lot of hard work with materials, design and manufacturing techniques to make it work. But finally all the problems were solved. Below is the equivalent illustration for perpendicular recording. As you can see,several spots can be squeezed into the same horizontal space as was achieved with horizontal recording.

Aah, I see. You are referring to the recording characteristics of the hard disk, and not how the platters are mounted in the drive.

You said that "all +400Gb drives are vertical platters".

Platters, are the disks inside a hard drive. They have always been fixed in the horizontal position, provided that the end user secures the device properly.

The round frisbee looking deal with a mirror reflection seen below is a platter:


Perhaps there's a little bit of confusion on your behalf. No pun intended.

Yeah I know a platter is the physical disk part. I thought it was obvious what I was talking about though...
