I have a WD2500JB hard drive. When I connect it, I don't hear it start, I only hear a beep. I guess it's completely dead, but maybe there is a solution, anybody can help?

It needs those things to start up. If you reinstalled them in the machine and it won't start up you need to check some things:
Does the screen flicker when you power it on or does it stay completely black? If it stays completely black, then the connection from the screen to the computer itself is lost. Normally it is caused by a broken cable.

If the screen flickers and then goes black, then check the following:
Does it beep at you? If it does, then the amount of beeps is important. It will state in the users manual what that numbers mean.
If it doesn't beep, then my best guess would be that there is something wrong with the power distribution in the machine.

Hard drives don't require special drivers. Should work perfect as is.

Not the answer you are looking for ... you will probably need a pro to get these files for you.

That is an old drive. No need to buy an exact replacement since that one is so old. Any hard drive will do. If your BIOS supports a larger drive, you can get an even higher capacity drive to replace it.

It is not necessary to buy an exact replacement hard drive. You can even replace the drive with a larger capacity drive. Find a local shop or look online.

Chances are your disk is partitioned. If it's your Operating System drive, you should reformat with your OS disc. If it's just a secondary drive, check in Disk Management (Windows) or Disk Utility (Mac/Linux) and you can re-partition the drive as you desire.
For windows, do search in the start menu search bat to find disk management, and in mac use spotlight to find disk utility.

Your hard drive is bad. If you are hearing clicking reptitiously it is you head not moving. Sorry about the bad news.

remove hard-drive and put it start in to your computer this sounds hard but isn`t. it sounds as the internal board has gone.

I assume the hard drive is installed inside the desktop computer.
Depending upon the age and make of the motherboard/BIOS, it may not support a hard drive as large as the 250Gb capacity. You maybe able to upgrade the BIOS version to allow it to access the full capacity of this hard drive. Go to the motherboard manufacturer's WEB site to download the latest BIOS firmware.

It's possible that the controller board on the underside of the drive has failed.
