You need to explain your issue better. Sounds like you attempted to rebuild your hard drive and wonder why it isn't working.

Suddenly my HD was no longer present in the bios. After several attempts not recognizable. Not recognizable in USB dock. Replacement heads, replace interface, both of the same 1TB WD hard drive. I have the HD plate in another - functioning - HD and then put it is not recognizable.

✔ Best Answer
Do you have a clean room setup in your basement? Did you suit-up & glove-up before working on them, like THS?

Here's why it can't be done in a non-clean room >> Notice the gap between the read/write head compared to the Platter Contaminants.

In other words, you destroyed the hard drive(s) the minute you opened the cases. You might be able to retrieve your files by taking the parts to a data recovery service, but I'm guessing it would cost a small fortune.

I do not entirely agree with you, the head and disk were after replacing it again functioning in the original HD. So any idea how I can get the data on the disk

Jan, if you yourself did the replacement than what Rider says is perfectly correct.

Unless you have access to a "clean room" there are no user serviceable parts inside a hard disk.

The only way you can get the data of the disk is with a data recovery service as stated.

is it a new drive? check connection.
if the connection is OK, and the disk still can't be seen in bios or disk management, then then there must be physical problem with the disk.

Sorry if you do not want to hear it but the only thing you can 'service' physically on the hard drive is SOMETIMES replacing the circuit board on the outside of the drive with one from a brand new drive of EXACTLY the same size and series model if the board or connectors prove to be bad. Once the drive itself has failed, Your only option is to pay a recovery service a lot of money to extract the data from the drive or pound it flat with a large hammer so no one else can if found and put it in with your metal recycling or trash.

It is too late already so try what you want but the chance of you being able to extract the data at this point if the BIOS does not recognize it is nearly zero.

You have to be a little bit crazy to keep you from going insane.
