| 1 | #define _PAGE_ Unlocking a password protected harddisk | ||

| 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> | ||
| 6 | Part. Error | ||
| 7 | Pls Chck HD | ||
| 8 | </pre> | ||
| 9 | |||
| 10 | <p>We are still not 100% sure why it happens. Theories range from | ||
| 11 | low-power conditions to accidental chip select failure. | ||
| 12 | It has also happened for normal users, | ||
| 13 | using the standard Archos-supplied firmware, although it's more frequent for | ||
| 14 | us developers. | ||
| 15 | |||
| 16 | <p>We do however know how to unlock the disk: | ||

| 18 | <h2>Windows/DOS unlock</h2> | ||
| 19 | |||
| 20 | <p>Note: This requires taking the Archos apart, which will void your warranty! | ||

| 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" => 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>. | ||
| 42 | 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. | ||
