I don't have the key sequence to get to the format handy but you'll need to know it.
I had the same issue. For some reason I tried this and got the device to power up in a sub mode that allowed me to download all the files off it.
plug into usb and hit the format sequence buttons.
this should bring up a base OS with light blue background. The device is now downloadable.
Next you'll need to format it from the PC.
Hopefully you have the AOS file for reloading the firmware (I don't remember if I had to do this or not).
Do it from the command prompt. You want to kill all hidden information that is corrupted.
Another thing I learned is that if you format NTFS it scrubs hidden information. If you format NTFS it will fail and tell you to turn off a property like safe removal.
Write down what it says and then goto windows explorer, right click, properties, turn of safe removal (what you wrote down).
Go back to command prompt and do ntfs format and then fat 32.
the hard drive is now completely clean.
click safely remove hardware and remove the archos.
try turning it on again.
As near as I can tell is there is a hidden partition that got corrupted and you need to wipe it out.
I have been using mine ever since.
Archos has no idea about this apparently. I just got lucky finding it.
