Platter damage.

[HDD_MASTER]

I have been receiving emails from HDD Pig (Great name) abobut some "impossible" platter damage. Does anyone else want to comment on this. I have seen loads of deskstars like this and I have been in data recovery for a long time. Am I the only one to see such things.

Now I have some time to post : no, you're not the only one. These drives suffered form bad heads to platter damage to poor engineering, I remember there were rumors about a class action. Anyway , glass platters are not uncommon, maybe in this case poor quality acceptance or processing lead to such disasters. Glass is an excellent material for magnetic and magneto-optic media despite the obvious fragility : glass is cheaper than the aluminium alloy used for platters, can easily be machined, made absolutely planar and if necessary could be given special characteristics by only adding certain materials/substances during fabrication, has excellent thermal characteristics compared with metals, can easily be "sputtered" with magnetic or metal particles etc. An excellent idea surrounded by poor overall engineering (the only thing I save is the electronic circuit and maybe the case) , despite the fact IBM has in-house capability of doing everything, from chips to magnetic media to precision machining to - obviously - engineering.
Of course, some damage is unrecoverable. Also, in IBM-Hitachi drives, the structure of the SA and the concept itself of the firmware make DR a pain in the ass.
However nowadays the quality standards are - now - acceptable.
That was my 2 cent.

I had a DDYS-T1850 SCSI that had 3 platters, there was only media left one one side of one platter when I opened it!

And a whole lot of magnetic black dust in the case

Yes... do some of you have at home a toy called "magic blackboard" where a metallic reflecting powder is removed by a pin from the rear side of a windscreen, moved in X- and Y- axis by two knobs ? The heads like exactly that way, and the data becomes dust and splatters all inside the drive. Everything starts from a head crash.

It's called "Etch-a-sketch"
