Hazards of hard disk internals in the house

The platters are very thin & brittle glass. When they shatter the shards are deadly sharp! GLASS? U sure about that?! |

Ceramic. Like ovenproof dishware.
I was under the impression most drives used them now. "Dave" wrote in message news The platters are very thin & brittle glass. When they shatter the shards are deadly sharp! GLASS? U sure about that?! |

You bend them,and you see the chromium?? layer break up(much harder then the disk itself). I have not yet come up to the point of disassembling gigabyte disks yet(they have to fail first -)-)-)-) ). |

I dissassembled some "DeatStars". Definitely metal platters. My guess that you need to look in the 200GB area for the ceramic platters. Arno |

Think any current IBM/Hitachi, probably. Most aren't. Define 'most'. If most then it must be easy to name one, right? So what did they do to solve the problems with aluminum substrate platters that the glass substrate was to solve ? |

Then they obviously weren't the 75GXP and 60GXP a.k.a "DeathStar"s. My guess that you need to look in the 200GB area for the ceramic platters. Arno |

I meant most older drives, I've opened quite a few from past years, typically up to 60GB size and they weren't glass unless there's a new glass formulation that allows it to bend. That doesn't necessarily mean most new drives are, it wouldn't be surprising if many have switched to glass or ceramic in more modern models. So what did they do to solve the problems with aluminum substrate platters that the glass substrate was to solve ? No idea, was it actually solving a problem or same thing different day, they they'd merely hoped to increase density more, and sought lower expansion and more rigid platters? Supposedly they're thinner too but I don't know that this is necessary unless there are several platters in the drive. |

The HD in my old laptop failed, so I took it apart to destroy the platter. I took a pair of pliers to it, and it shattered into a thousand shards. They sure looked and acted like glass! |
