Re: Q:Ram issues: YO Paul
My email is invalid. If I'd known about the rules about how to properly
form an invalid email address, I wouldn't have used a "real looking" address.
But for as long as I want to be able to trace my own messages in Google
Groups, I'm stuck with it.
I don't use email, because the newsgroups are public and all can share.
Kingmax likely does not make their own memory. You can buy memory
chips with nothing printed on the top, and affix your own labels.
You can probably buy "bare silicon die" and do your own packaging.
Fewer companies would have the capability to make the silicon itself
(and be cost competitive).
The Kingmax web site is not helpful. You probably know more about the
product, than they do.
For some time, hard drives have used "embedded servo", which is
information written at the factory, to make it possible for
the head assembly to track the information on the disk. A
"low level format" cannot replace all of the magnetic areas
on the platter. The data portion of the sector can be overwritten,
but not the servo.
Previous generations of hard drives, used a "servo writer" at the
factory, to install the servo information. Apparently, the mechanical
tolerances are now so small inside the drive, that the external
servo writer is insufficiently accurate for the job. So they somehow
now use the drive itself, to write the servo. (SOme kind of timing
generator, lives on the drive controller.) But I don't think
that means the drive is capable of rewriting all magnetic info.
I expect the end user is still prevented from overwriting servo.
