4<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:
5<pre>
6Part. Error
7Pls Chck HD
8</pre>
9
10<p>We are still not 100% sure why it happens. Theories range from
11low-power conditions to accidental chip select failure.
12It has also happened for normal users,
13using the standard Archos-supplied firmware, although it's more frequent for
14us developers.

16<p>We do however know how to unlock the disk:
17
18<h2>Windows/DOS unlock</h2>
19
20<p>Note: This requires taking the Archos apart, which will void your warranty!

22<ol>
23<li>Grab

25(written by

27<li>Create a bootable DOS floppy disk, and put atapwd.exe on it
28<li>Remove the harddisk from your Archos and plug it into a laptop (or a standard PC, using a 3.5" =&gt; 2.5" IDE adapter)
29<li>Boot from the floppy and run atapwd.exe
30<li>Select the locked harddrive and press enter for the menu
31<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.
32<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.
33<li>Your disk is now unlocked. Shut down the computer and remove the disk.
34</ol>

36<p>Big thanks to Magnus Andersson for discovering the Fujitsu (lack of) user password!

38<h2>Linux unlock</h2>
39
40<p>For those of us using Linux, we have written
41<a href="mail/rockbox-archive-2002-03/att-0010/01-isd200.diff">an isd200 driver patch for unlocking the disk</a>.
42This 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.
