Unlocking a password protected harddisk
During development of the Rockbox firmware, on several occations the harddisk has become locked, i.e. password protected. This results in the Archos displaying:
Part. Error Pls Chck HD
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.
Note: None of us developers have experienced this problem since march 2002.
We do however know how to unlock the disk:
Note: This requires taking the Archos apart, which will void your warranty!
Big thanks to Magnus Andersson for discovering the Fujitsu (lack of) user password!
There is also a program for win32, ArchosUnlock.exe, that creates a linux boot disk with the below mentioned patched isd200 driver.
For those of us using Linux, we have written an isd200 driver patch for unlocking the disk. 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.
