Hello to Everyone, First I want to thank all those who share their investigations and results. I built my inteface according to this schematic: http://www.llamma.com/xbox/download/ST3100...l%20english.pdf It worked perfectly but ... the driver still refuses to be detected by BIOS. The problem with my Seagate 7200.11 500GB HDD started about a month ago, sometimes, while using the computer a low click sound came from the hdd (almost unaudible) and it stopped working. As it was the OS computer the whole system just hunged in seconds. If I tried to press reset bios just didn't detect the hdd, I had to turn power off and on again in order to get the hdd to be detected. Two days ago it just completely died, the hdd is no longer detected by bios. I tried the BSY recovery method and everything went smooth but the hdd still behaves the same way. I cannot understand what is going on, it seems to me clear that it is the BSY problem but I can't get rid of it. If I boot from the firmware update cd and once it is loaded I power up the hdd it detects it (after I hear the motor running), but after a couple of seconds it stops and obviously I cannot flash the new firmware. I'm mad at me for not being able to recover it, any help would be very much welcomed. Cheers.
