HDD randomly disappearing in windows 10


One of my hard drives will randomly disappear in win 10. It's not recognized anywhere (disk management, task manager, explorer, crystal disk info. It's just gone.) but if I put the computer into sleep mode then log back in or restart it shows up again with no data loss. Is there a setting that could be causing this? or is the drive just dying? (its only 2 months old)


It's a 6tb Wd red pro with a 32gb optane cache. Xi hero mobo. 1300watt evga 80+ gold psu.


I swaped the sata cable to a new one and tried a different sata port on the mobo.. swapped the sata power cable to a new one and used a different port on the psu. I set HDD shutoff to 0 in power settings. Crystal disk info is not reporting any problems when the drive is working.

Even after trying all that it's still happening and I have no idea what could be causing it.


More Info:

there's also a NVME OS drive and a sata ssd and I'm not having problems with either of those.

I used the program "intel optane memory" to link the optane and hdd.
