[ale] SATA Hard Drive Issues?

[Lightner, Jeff]

Actually it happened under warranty and at Sun's suggestion.  Of course
we were a major multinational and had installed the Sun solution as a
middle ground test for long term solution so Sun might have been
treating us better than they would have otherwise.   

 

Unfortunately for Sun (and me) the company went with an IBM mainframe
solution for DB which meant they didn't really need many UNIX Admins for
the few AIX front end servers they were going to have.   The funny thing
is I get a headhunter email at least once a month saying my skill set
would fit well with the company's then current job opening. 

 

By the way speaking of Sun - Last week the EU cleared the Oracle
acquisition and today Oracle announced they had completed the
acquisition.

Yes. Amorphous diamond coatings are applied to (some) hard drives. But
I'll bet the replacement order from Sun didn't happen until after the
warranty was over :). 

Diamond dust in the drive factory would be a major fubar event. The
platter coating process by default must be kept away from everything
else int he factory as it does make sub-micron size "clinkers" that are
diamond-like and can thus be a major contaminant.

It's my understanding that laptop drives in particular are coated with
a fine layer of diamond in order handle the banging around they get.
So it is not unreasonable that they got a bunch dust in the wrong
place.
