Seagate HD in BIOS but not PC Question

Have a 1TB drive pulled out of a FreeAgent GoFlex case. I connect directly to SATA connection on the MB and it is recognized by the BIOS but not by Windows/Linux bootdisk/Seagate Seatools. It doesn't show up in Device Manager or SeaTools does not see it. The drive powers up as I can feel the motor. I can't hear the heads move but it is a quiet drive so I am assuming that they are not stuck.

What is throwing me for a loop is that the BIOS can see the drive yet SeaTools does not. I would think that they pull the drive info from the same location. If the PCB has failed, wouldn't that mean that the BIOS would not see the drive as well? Even if something like the heads or platters have failed, wouldn't the Seagate tools still be able to give drive info such as model number and serial number, etc?

Any suggestions on where to go from here? It is not my drive otherwise I would open it up and see if the heads move during power up.

Some SATA ports are shared with the M.2 slot. Be sure you're not using a shared SATA port. Also, some SATA ports use another controller that's not the Intel Chipset, so drivers might be missing to enumerate the drive at the OS level.

Essentially, try moving to another SATA port on the motherboard.
 


Maybe the disk need to be initialized (All data on disk could be erased)

Does you see the disk in Disk Management?
Right click 'My Computer'> 'Manage'> 'Disk Management'
Right click the Seagate disk and select 'Initialize', then create a partition and assign a driver letter.

I figure the drive is bad. It slows down the system as well. I'm just trying to determine what component has failed whether it is the PCB, heads, platter, motor, corrupt firmware and if any data on the drive is salvageable. The drives owner said that Seagate will back up the data and put it on a new drive for $600. Let me caveat this with, that is what they told me and may not be the case. It is up to them how to proceed. I wouldn't mind opening the drive to see what is going on inside but I must let them figure out what they want to do first.

 


Recovering data is a very lucrative business, you could pay from hundreds to thousands depending of the media and size.
Unless you are trained professional recovering data, it is not a good idea to open a disk to take a peek.
Disk components are extremely sensitive to dust, moisture, etc and can make harder and sometimes impossible to recover the stored data.

Not only that but if the drive were to be in warranty opening it up would void it.

The drive is out of warranty. As far as opening up the case, I wouldn't do so unless they decided that the drive is a lost cause and the data on it was not worth sending out to be recovered for an exorbitant price. Assuming I was able to somehow bring it back to life, I would immediately back up the data then [strike]trash[/strike] recycle the drive.
