Disk Hitachi HDS721025CLA382 has worked for 6 years well and quietly. However, since it has not much space, there were not always enough place for video and textbooks. The processor is also slow, it's Pentium 4, 2GB RAM. However, websites when loading took much place, video and music also took lots of disk space, that's why the processor has always been loaded on 100% and free disk space rarely was more than 5 GB. I always had to delete old files before I downloaded new music or books. Browsers were also very slow, they took up the entire operating memory and loaded processor on 60%. Recently, few days ago, I freed up nearly 20 GB of space, I decided to download my favorite tv-show through torrent. When the video file was downloading I heard the sound of a spinning spindle or parking of heads. Initially the intervals between spinning were small, and then more frequent and louder. And suddenly it gone quiet, the desktop with the cursor did not move, only time on the taskbar was working. So, I shut down the computer. And then, in an hour, I tried to turn computer on, there was a quiet clicking and spinning sound, and the message "reboot and select proper boot device or insert a boot media in selected boot device and press a key" on the screen. Next times I was trying to turn hdd on again and every time I heard only silence from it like I didn't work anymore. I wanted to scan disk for errors with HDDScan, but BIOS doesn't detect the drive. So what do you think could happened to it so suddenly? I want to try to repair it on my own, so I need your help with it. How do you think could the problem be in the controller board or in printed circuit board?

Sounds like it's a goner, with the disk heads hitting the platters and not being detected by your bios.

Have you check to make sure the power connection hasn't come loose? It could also be a bad motherboard. I've had drives not spin up if the IDE or SATA controller failed. Try putting the drive in another working computer if you can. If it isn't detected on that drive, then it's toast.

Unlikely. It sounds like a problem with the heads. Although it could be a power loose issue as well.
It's not a power loose issue. I have only one computer. And now I connected to it WD disk, and it works fine. When I connect Hitachi again to the same cable it doesnt't produce any sound. Like it's dead. But central chip LSI, which I think is a hdd controller is becoming hot. What does that mean?

It's dead. The board may still produce heat when connected to power if the circuit board works, but the motor, heads or read coils are broken.
Wrap the enclosure in plastic wrap, tightly. Freeze it overnight. you MAY get it to power on in an external case long enough to retrieve data. But it's not looking good. I hope you have a backup.
You need to have a back up always if the data is that important to you. Waiting til you have issue is not a good idea. It could die in the process of being backed up.
Absolutely correct. But you also retrieve anything that you do not already have backed-up (or vitally need) at the first hint of problems, and that it often not soon enough. Sometimes the first sound you hear is also the last sound you hear coming from that drive.
