M.2 drive not recognized on Prodesk 600 G1 mini

[Downwards]

Hello, 

I've searched the forums here and seen this issue pop up a couple times in the past. Older mini PC (G1) and using a M.2 SSD. It looks from the history here that some folks have had success using them but they have to be PCIe and not SATA connections. 

I bought an "HP EX900 M.2 120GB PCIe 3.0 x4 NVMe 3D TLC NAND Internal Solid State Drive (SSD) 2YY42AA#ABC" and it doesn't appear to be recognized. 

I pulled the original drive and installed the m.2 so that there would be no additional drive causing confusion. Installed windows 10 with a usb flash drive. It did recognize the drive and formatted it- looked like it installed everything. After reboot however (pulled the usb drive first) it said there was no drive in the computer. 

Gone into BIOS and I can't see where it is recognized at all. 

If I try and re-install windows 10 I can see that the drive has been partitioned as if it installed windows successfully, but cannot boot the machine with any changes in the bios (EUFI or Legacy). 

Any ideas why? 

The M.2 is a known good device.

Hi Downwards,

Welcome to the forum.

I am not a HP employee.

Please refer to the specs for your PC at this site (Link). Look at the interface specifications for all storage devices. They are all SATA. Some are the legacy SATA II spec.

This is the first time I have seen this but it appears your MB SSD M.2 socket only supports SATA.

Hello Downwards,

It IS possible to boot that M.2 drive in your HP Prodesk 600 G1 Mini.  I have the same computer AND the same M.2 drive! However it will require you to create and keep attached a USB boot drive called a Clover stick.  This is because your HP Mini UEFI and Legacy BIOS doesn't have boot support built in for M.2 slot devices.  It might be more work than you want to set it up but please review my post here:

Also I have confirmed in testing that you can NOT use a SATA based M.2 drive in the slot so you already do have the right hardware to proceed.

Please let me know how it goes or if further help is needed.
