Before it got to this point I was having issues stated in my previous thread, Now I’m stuck with my M.2_2 no longer detecting drives.
forums.tomshardware.com
After leaving it alone and going to bed frustrated, when I woke up and started trying to get it working again the drive was detected in the bios.
Exiting the bios happy thinking my issue magically fixed itself, the system shut down then instantly started up again and the drive was once again gone. I have tried 3 different drives in the M.2_2 slot and none are picked up anymore. Even the original drive that was placed into that slot and worked fine for months.
All drives work and function properly in M.2_1. I really have no idea how this could have happened and any help trying to get to the bottom of it would greatly be appreciated.
