corrupted firmware

Hello!

I have a problem with a Hitachi Travelstar HTS548060M9AT00.
On last weekend I have changed some parameters with hdparm on Linux, because the harddisk was a little bit slow.

After the next reboot some minutes later, the hd didn´t spin up again :shock:

The bios is not able to detect the hd correctly. I think the firmware is corrupted.

Is there any way to reflash the firmware, even if the bios isnt able to detect the harddisk?

Thanks in advance.

Are you sure it's not spinning?
If it's not spinning it looks like not a firmware problem. Either PCB is dead or the heads are stuck to the platters.
You can open the drive and if the heads are not on a parking ramp you can try to move them gently to the parking position by slowly rotating platters. But that's just for data recovery - I wouldn't use this drive after that.

Yes, I am really sure that it isnt spinning.

I switched off all fans and there is nothing to hear, only a single quiet click from the headers.

Maybe I should try your advice.
But I still have warranty until 22th april. I am not sure if I am able to open and close the device, without leaving any mark.

Opening the drive will for sure invalidate the warranty.
I would do that only if I care about the data and don't have money for professional data recovery company.
