| #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 happens. 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's more frequent for |
| us developers. |
| |
| <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! |
| |
| <ol> |
| <li>Grab |

| (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. |
| </ol> |

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

| <h2>Linux unlock</h2> |
| |
| <p>For those of us using Linux, we have written |
| <a href="mail/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. |
