You do not want to know what happens when you have bad RAM, so, if you're buying RAM, make sure it's good. The best you can do is buy from high-volume distributors who offer a good exchange policy. Hard Disks Hard disks are very well made and supported even better. From time to time a manufacturer puts out a bad batch and everybody grumbles for a few years. However, on the balance, it's hard to get a bad drive these days.
Hard disks are mechanical devices, though, and they're sensitive to vibrations.
In the same way that a fish tank will crack if there are too many trucks passing on the road outside, vibrations can kill a hard disk. When the drive is working, don't shake the computer. Avoid vibrations as much as possible, and always make backups. Too Short No comment After entering your name, e-mail address and comments, press the SEND button above to mail your comments.
