Hi there, this is my first post in this forum, I would suggest that the guide and info from aimtrading have some picture, or diagram for clear view. As the title, 'newbie', perhaps some newbie quite confuse where these term are located, such as me

explained so well that this newb almost understands it!

so here are my newb questions then:

1) where can i get the Samsung firmware writer?
2) is there any Samsung firmware available?
3) is it possible to update/upgrade the firmware on a Samsung SP2504c drive form vt100-41 to vt100-50?
4) have i posted this in the wrong thread? :oops:

i have no real reason for doing this, other than my fetish for having the latest drivers and firmware for my equipment.

cheers,
Andre

I'm new to the board.... thanks for the info so far!

I had a drive or two every now and then that needs data extracted from it... now I just crashed my main drive and need of ton of things extracted. I figured I should start learning....

The SA is stored on 'negative cilinders' of the HDD and therefore is not accessible by normal read commands. However, the area can be accessed with other ATA commands. An example of a (more or less) 'standard' ATA command that can access info on the SA is the 'download microcode' ATA command, that can be used to update information in the firmware code module. However, most of the commands that can be used to access the SA are vendor specific. Since vendors (obviously) don't want users to mess around with the SA, these commands are generally not made public. However, these commands can be deduced by, for example, reverse engineering the firmware code itself.
Aimtrading.

I dont understand - you say above that normal commands cant read the SA - yet you say you can deduce the commands by reverse engineering the SA. How can you reverse engineer the (commands) to the SA if you cant read the SA in the first place?

Confused,

SA also means ROM. If you know how to read these and then what to look for you can glean a whole host of info from these.
