#define _PAGE_ Unlocking a password protected harddisk
|
|
#include "head.t"
|
|
|
|
<p>During development of the Rockbox firmware, on several occations the harddisk has become locked, i.e. password protected. This results in the Archos displaying:
|
|
<pre>
|
|
Part. Error
|
|
Pls Chck HD
|
|
</pre>
|
|
|
|
<p>We are still not 100% sure why it happened. Theories range from
|
|
low-power conditions to accidental chip select failure.
|
|
It has also happened for normal users,
|
|
using the standard Archos-supplied firmware, although it was more frequent for
|
|
us developers.
|
|
|
|
<p>Note: None of us developers have experienced this problem since march 2002.
|
|
|
|
<p>We do however know how to unlock the disk:
|
|
|
|
<h2>Windows/DOS unlock</h2>
|
|
|
|
<p>Note: This requires taking the Archos apart, which will void your warranty!

(written by

|
|
<li>Create a bootable DOS floppy disk, and put atapwd.exe on it
|
|
<li>Remove the harddisk from your Archos and plug it into a laptop (or a standard PC, using a 3.5" => 2.5" IDE adapter)
|
|
<li>Boot from the floppy and run atapwd.exe
|
|
<li>Select the locked harddrive and press enter for the menu
|
|
<li>For Fujitsu disks: Choose "unlock with user password", then "disable with user password". The password is empty, so just press enter at the prompt.
|
|
<li>For Toshiba disks, if the above doesn't work: Choose "unlock with master password", then "disable with master password". The password is all spaces.
|
|
<li>Your disk is now unlocked. Shut down the computer and remove the disk.

|
<p>Big thanks to Magnus Andersson for discovering the Fujitsu (lack of) user password!
|
|
|
|
<p>There is also a program for win32,
|
|
<a href="http://www.ws64.com/archos/ArchosUnlock.exe">ArchosUnlock.exe</a>,
|
|
that creates a linux boot disk with the below mentioned patched isd200 driver.
|
|
|
|
<h2>Linux unlock</h2>
|
|
|
|
<p>For those of us using Linux, we have written
|
|
<a href="mail/archive/rockbox-archive-2002-03/att-0010/01-isd200.diff">an isd200 driver patch for unlocking the disk</a>.
|
|
This modified driver will automatically unlock the disk when you connect your Archos via USB, so you don't have to do anything special. Apply the patch to a 2.4.18 linux kernel tree.
