Here are a few things you can check about this issue:
- Was there any change or event around the time this issue started? (Power Outage, Hardware change, new software, system updates, etc.)
- Confirm that the SSD is in a PCIe* 3.0 x4 Slot.
- Go to Device Manager - Storage Controllers and check if the Intel® SSD Data Center Family for NVMe Drivers is displayed, it shows as Intel® SSD P3700/P3600/P3500/750 Series. You could also check if the drive is shown in Computer Management - Disk Management.
Thanks for the reply.
-No hardware or software changes. Computer was powered off overnight, connected to a UPS.
-Have tried the card in two x16 slots and two x8 slots, all of them are PCIE 3.0 slots.
-Device is not shown in DeviceManager, Disk Management or in the Intel SSD Toolbox.
I have just tested the card in another computer in a x8 PCIE 3.0 slot and it also does not show up in Windows or BIOS.
