HI. I have Western Digital (model WD400BB-00CAA0, S/N WMA8H2247875, 40 GB) IDE disk, that unvisible in BIOS -> unvisible in OS Windows. Is there any way of recovering data (without of replacing the controller)?

Yes it is possible. You will need to find your local data recovery lab where they can diagnose the fault for you.

You have Western Digital Drive that is not seen in BIOS. To be fair, this does not mean a lot. the first step is actually diagnosing the fault, which you may not be able to do correctly without specialist knowledge and equipment. Assuming you are able to diagnose correctly, do you have the relevant tools/equipment/parts/skill/knowledge to repair the fault?

Maybe if you can give more information regarding any symptoms, is the drive spinning, does it make any noises, was the drive dropped etc.

If data is important then it is very important that you get this dealt with by a professional, and you must refrain from opening the top cover. If data is not important and you are curious, then it is your choice but recovery or repair is unlikely without a professional.

I work in a company that distributes, implements and maintains special programs for accounting. One of our clients had brought the disk which does not work. There is the databases on the disk. The disk was not dropped, broken, etc. The client said that "Yesterday all was well. And today we turn on the computer, but he was not worked." May be is there any software that may I use?

Yes, of course, there is a software wich can help depending on the problem.
But the software is a software-hardware complex, and the price is much much more than paying for one-case data recovery in the nearest lab.

Without the proper diagnose, you can make things only more bad.
If you open the drisk's clean area, the recovery price will be doubled in any lab!
Additionally WD is a special case, not all the company can solve all the problems on it....
Keep this in mind....

yeah. it no too hard to do. but need pro tools for process.
