A friend lent me an old HDD so I can use an OS and extract whatever is salvageable and yeah, the SSD is now an Unknown Device in Device Manager's disk drives. Unallocatable by Disk Management. Disconnects the moment the PC boots into anything and when we tried to boot it on 2 different motherboards and none of them recognized it or could use it. So I think if your sata disconnects your SSD then it's the SSD's fault not anything else, rip all of my savefiles that weren't on a cloud. As for what could have caused it, between power surges and constant use at near full capacity, who knows... the site that still distributes this brand got review bombed. Hope this helps anyone who may experience this!

I've had this MSI A68HM-P33 V2 for roughly 1 year and 3 months now, came with a AMD Athlon X4 840 and a 4GB SDRAM Kingmax, I had my gpu for over 2 years now, a Radeon RX460 and an HDD Toshiba DT01ACA050thats older than 6 and had been reinstalled 4 times.Now, to my problem.I have a Teclast 240GB A800 SSD which I don't think is older than 8 months but was bought from a retailer known to sell 2nd hand hardware.I installed my OS there with the thought that it's faster than my old HDD.After I boot my PC I am met with the EFI shell and when I check the board explorer in BIOS the SATA port 1 where I have my SSD is empty.I found out that if I unplug and plug in the PSU cable and restart, then spam the button to enter BIOS the board explorer sees it and recognizes it.After I save and exit by putting it to boot from the SSD the PC resets and puts me in EFI Shell, when I type exit and return to the BIOS the SATA port is empty again.I've tried: Switching cables Switching ports AMD-RAID BIOS launch Rearranging Boot options Disabling and enabling win8/8.1/10 configurations Disabling fast boot Restoring defaults Overclocking Resetting hardware monitor to defaults(for some reason it says my CPU temp is dead frozen at 128C and fan speed at 1850) Disabling, enabling and defaulting power timers I have also ran into different things since it started to occur: BSOD CRITICAL PROCESS DIED BSOD INACCESSIBLE BOOT DEVICE BSOD CRITICAL SERVICE FAILED Boot manager status 0xc00000f I welcome all suggestions and will ask on different sites and forums as well. If you need more information I'll try to provide asap!Thanks in advance!Sorry for the long wall of text,TLDR: MSI BIOS disconnects SSD SATA port on reset
