About a week after I built my PC, my PC started running slowly so I restarted it and then when it restarted my WD 2tb black hard drive was not showing up in windows. After a restart it appeared again so I thought it would be a one off occurrence however it happened again a few days later, and again another few days later. I also check the BIOS and the hard drive wasn’t showing up there either. I tried changing the SATA cable, the SATA port and the power cable but it still happened. I eventually came across the power management settings and made sure that the power saving settings were turned off. My hard drive hasn’t disappeared since changing the power settings however it seems to be running slow now. In disk usage in task manager it always seems to be at full usage at less than 2MB/s. I have used the Western Digital diagnostic tool and have run multiple Quick Tests and Extended Tests and they both say the drive is okay. I will provide screenshots below of the results from all of the tests I have carried out. If anyone could help me fix this problem or let me know if I need to replace my hard drive it would be much appreciated, thanks.
