First, hard drives were designed to be mounted flat. You can’t turn a hard drive on its side, and expect the bearing to last more than a couple of years. In 90% of the replacements on computers under two years old, the hard drive has been mounted on its side, usually for space considerations. This puts excess pressure on a small part of the bearings of the hard drive. By mounting the unit flat, the weight of the disk in the hard drive is distributed evenly over the entire surface of the bearing. This reduces the wear on the unit, and promotes long life.

Second, when HD’s are placed above other heat generating devices or are sandwiched in between various parts without any circulation room, they fail more often.

Remember that your hard drive has a motor and moving parts. All of which generate heat. The more room your system has to circulate the heat, the better your system will run. The easier the excess heat can be vacated from the system, the longer it will last.

Check to see that your hard drive is mounted flat. All you will need to open up your system’s case is a Phillips head screwdriver (the plus sign tip) and sometimes a standard screwdriver. If you find that your hard drive is mounted on it’s side, check to see of you have some spaces available under the floppy drives and CD-ROM. If you need to move the other drives up, that’s ok.
