I'm afraid it may be not possible to "fix", it may be too late when a hard disk reached this point.
This happens when the disk surface can't be accessible at all - when the firmware and/or the adminstrative area of the hard disk damaged and the drive even can't provide the correct system parameters.
As you can see, the hard disk drive does not show any identification information (its model ID, firmware version and even its capacity is not provided correctly).
This is generally why it's not available in Windows for use: it can't be read/written, can't be tested - and can't be "fixed".
Not sure if this is an internal hard disk or external hard disk drive.
If it's a 2.5" external hard disk, connected to a single USB 2.0 connection, then I'm afraid such failure is very common as a single USB 2.0 port can't provide enough power for proper operation. Using an external hard disk that way can cause complete, unrecoverable "sudden" failure.
So if it's a 2.5" external hard disk, make sure to connect to USB 3.0 port or connect to an USB hub with external power supply to provide enough power for proper operation.
If this is an internal hard disk drive and you have the opportunity, I'd recommend to check
- connecting the hard disk drive to a different SATA port and power source, maybe check with a different computer
- check with an external, USB enclosure / adapter
just to verify that with the different operating environment and conditions (different connections, power source, etc.) may help the hard disk to identify itself correctly.
If the drive can't be detected in any cases then I'm afraid this may be caused by a permanent damage of the hard disk, for example caused by overheat condition (see
http://www.hdsentinel.com/hard_disk_case_overheat.php for details) or mechanical shock (or the insufficient power mentioned).
On the above link, it is described that during such damage, the hard disk internal firmware may be damaged/broken. The result is that the hard disk can't report its actual model ID, serial number and/or the real capacity (as you can see).
If this happened, I'm afraid no software can help - as no software can make it working again, no software can fix a completely failed hard disk drive.
Hard Disk Sentinel is designed exactly to avoid, to prevent such situations: to reveal and fix any possible problems long before it can result in a failed hard disk. Fixing is always more problematic (if possible at all).
The cost of data recovery can be high (if it's possible - which is not true in all cases) so it may better to avoid this by constant monitoring and tests available in Hard Disk Sentinel.
