What could be the problem?

In General, the point of this, put on a PC ssd drive which works together with a seagate 1tb hdd. At some point the system began to slow down wildly, after a reboot, the hdd drive is no longer detected by the system (as if the drive is not connected) how to fix the situation?

Judging by the description of a drive failure. Check on another computer, if not determined by change healthy.

1) Change SATA cable to the HDD.
If the disk is not visible,
2) Connect SATA cable to another SATA port on the motherboard
If the drive is still not visible, and hands not quite the curves, then
2) Unscrew the HDD cost and carefully eraser to wipe the contacts of disk heads on it. Two rows of contacts.
There screwdriver torx T8 or T6.
@wulfdogif the data is not needed, it is possible to wait the end of the warranty. - Marjolaine_Glover commented on March 19th 20 at 08:36

The drive when power is applied does not emit unusual sounds (clicking/rattling, grinding, squeaking/buzzing etc.)?

If Yes, and you need information from it, then disconnect the drive and stop the attempts - alas, but at home nothing to do.
Clicks, knocks there - hosea.Huels94 commented on March 19th 20 at 08:38
@hosea.Huels94, Then, it's unfortunately game over for independent attempts. Most likely, the disk has problems with the heads (also possible damage to the surface, this is a common problem for Seagate) and nothing to do.

Moreover, be sure to keep in mind that in this state any attempt of inclusion could either greatly hurt, or to make recovery possible at all, because either the drive will attempt to read the service information or the OS will try to work with it as with the live. The result is a washed down (s) on the surface of the plates.

If you need the data from the disk, put it aside, choose a company dedicated to professionally restore the data only, and go to him. Here is a memo-educational program choice:
