I know he got ATA error 11...

If you read the entire thread, you will see that it is indeed a hardware problem...

I have a second unit (broken) and maybe I can replace the chip.

It is the large chip marked LVCH16245A in this picture: http://download.rockbox.org/device-pictures/iriver/h300_back.jpg

Note that this is only a theory. Since the USB mode works, the HDD connector seems to be working, which leads me to think that it could be the connection to the CPU that is broken. The signals from the HDD connector are buffered by the LVHC16245A chip.

koala007:
But why would this chip go bad by doing just a simple battery replacement job (I'm not questioning your theory).

I have no soldering experience with SMD components so I keep the unit for spare parts unless you have an other idea.

I can't flash the eeprom with a new firmware because I can't get access to the harddisc by the menu (even format by the menu is not possible).

One common cause is electrostatic discharge (ESD). It's easy to zap sensitive components if you don't take precautions when working with electronic devices.

Since it happened when you changed the battery, there is a risk that you have damaged the power supply circuit. Do you hear the drive spin up when you start the player?

Don't bother. The EEPROM is not involved in this, trust me.

koala007:
LinusN, your assistance is very much appreciated.

I can start the player with the iRiver firmware 1.29K but it shows me 0 folders and 0 files. I can change language etc in the setup menu but there is no reaction when I try to format the HD or make a firmware update (The HD spinns normal).

I won't get access to the HD when I choose music or picture in the menu.
This happens with a brand new HD or the original HD.
So the problem is not the drive.

LinusN:
If the drive spins, then it is not a power problem. That leaves us with the ATA buffer... I'm out of ideas. Sorry.
