Why is my HDD slowing down my PC?
OK, so I've got a Toshiba 1TB HDD, but my old HDD (WD Caviar Blue 250GB SATAIII) slows down my pc everytime I plug it in. I plug in the SATA, the SATA Power, but when I try to open it anywhere, Windows Explorer crashes, Diskpart is not listing the disks, and Windows installers (I tried wint 7, 8.1 and 10) don't load in, and if I try to boot from it, it says that "Non-System Disk or harmed disk. And when i try DPS Self-Test in BIOS, it says that " disk replacement recommented", and I don't know what to do with it, because some important files are on it.
Thanks for any help!
