Hi,

I am new here and new to harddisk recovery. I hope people here are kind and can help me or guide me in what direction to seek help to my headaches.

I have a Hitachi (IBM) Travelstar 2,5'' disk that is not detectable by BIOS. When the drive starts it clicks 1 or 2 times (hard) with the heads, apparently trying to load the system info.

I have almost identical drive (newer revision / MLC version) that works fine. Changing the PCB from the defective drive to the good one works, but not the other way. So the PCB must be OK. The error must be in the mechanics or the system area / firmware of the drive.

MHDD does not detect the drive. ID command returns an error "drive not ready". RST command does not show an error, but the T0NF error register is set ON and the last register shows code 2.

I would be glad to get any help to diagnose or repair the drive. Where should I look for tools and information? How can I determine if it is mechanics/preamp error or system software corruption?

Also to mention, this is my private disk I am trying to recover. I am willing to pay for tools and knowledge, but the data on it is not worth astronomical amounts of money. My guess is that firmware error will be cheaper for a professional to repair than hardware error requiring opening of the drive in a clean room. Am I right? If so, where do I find (in Scandinavia or Nort Europe) a good data recovery company specializing in Hitachi (IBM) notebook disks? Can I download or buy (for reasonable price - I'll need it only once) tools that can repair damaged firmware?

Any help will be highly appreciated. Thanks!
