The problem of HDD from Seagate

In General, I was drawn to this problem. I have an old Seagate barracuda 7200.12 500GB on which I for a long time used as a primary for Windows, and storage information. Last year, I bought myself a 250Gb SSD for under games, but since playing I have become much less recently decided to reinstall Windows on the SSD. Reinstalled, everything was fine, but as a week passed, I have ceased to work normally with my old HDD. The system sees it and recognizes it, but the open sections are not wants. One sees the partition fine on the 60GB, which was once under Windows, and the other does not recognize the size and does not open. Maybe someone knows what's the problem? It's a pity not more HDD than data that is on it, is there any way to get it back to normal working condition?
