Hello. I've recently updated my computer by adding new hard drive to it. After doing that my OS (win 10) broke and i installed it clean the same day on my SSD (i had to format it). Now my new HDD works fine i believe but my old one (which was not formatted) keeps disconnecting, and whenever i try to save something on it i got an error message saying that device is not existent. Thing i need to say that the old HDD is with me from around 6 years so it can be just dead but it worked fine like 2 weeks ago (i wasn't at home by this time). The HDD seems to be working fine for around 5-10 min after turning on the computer but after that i can hear something like the disc inside stops spinning. I tried to use HD Tune PRO (trial version) to see if it can tell me something but i couldn't start benchmark, there was no info under the "health" tab and after using error scan it scans like 2-4 squares and detects all of them as "damaged". I tried formatting the drive but it did nothing as well. Making new partition or changing assigned letters made no diffrence too. I know its possible that the drive is dead but i don't think so. I don't think that there is a problem with a power supply because all HDD's and SSD are connected with the same cable (with the corrupted one with the middle plug).
PS: I calculated PSU usage few times and it should not be a problem (Ryzen 7 2700x, gtx 1060 6gb, 2x8gb ram, 2 fans, 2 HDDs and 1 SSD for 650W power supply)
