Inspiron 7000 Gaming (7577) - Problem adding 2nd hard drive

Hello, I'm basically having the exact same problem as referenced in this thread : http://en.community.dell.com/support-forums/laptop/f/3518/t/20021480 

I received the laptop yesterday. It came with the 256gb Toshiba NVME SSD and an empty SATA slot. After updating windows and installing the latest drivers from the dell driver support page (included the latest bios, version 1.1.3) I turned off the machine and installed a Samsung 850 EVO 500GB SSD in the spare SATA slot. As in the referenced post when I turned the laptop back on the hard drive was not seen by the BIOS, Intel RST, or Disk Management within Windows. The BIOS is set at it's defaults which are UEFI and RAID I believe. I went through the Dell Diagnostic and no issues were found, the laptop performs perfectly except for this issue.

I'm happy to go through troubleshooting but in the linked post user ttmcmurry has really went all out documenting the issue so I'm not sure what I can add on that would be helpful.

Hello, just received my 7577, exactly the same problem. In this case the ssd is a Crucial MX200 500GB.

HDD, no problem, SSD, no go..

The system ships in RAID mode, which needs to be changed to AHCI in order for the system to pick up the additional drive.  This will require either a reinstallation of Windows onto the original drive, or a boot into Safe Mode to enable the AHCI drivers for Windows 10.

ein63 normally that would work but from my own experience and the various test ran in the other dell thread linked in my first post that is definitely not the case with the 7577. I have the bios currently set to AHCI and the second SSD isn't detected in the bios much less in Windows itself.

Same problem here too! Just bought a dell 7577 and added a second ssd in the open bay, the pc will not detect it, no matter what I do. I tried calling dell, but that was an absolute joke!

On my 7567 I am running a Samsung PCIe M.2 drive so I do not still have the factory installed M.2 drive, just in case it might make a difference to the discussion.  My system runs with the SATA controller as ACHI to accommodate the second drive on the SATA controller.

Did the unit come with the cabling needed for the extra drive?  Did you check to make sure it was connected at both ends?  If the Bios doesn't see the drive then you certainly can't format it.  I suppose for the same reason the Intel utility does not see the drive.  

There may still be some sort of bug in the Bios which is keeping the system from seeing the second drive but you should be able to run the system as RAID without problems.  Also, I don't think I added the second drive until I had removed the original drive which was configured as SATA.

If anyone thinks it might help to test on a 7567, I will set my system back to the Factory configuration (LiteOn NVMe) and test installing a secondary 256 GB 2.5 inch SATA (Samsung) drive.

Well, I tested my system (7567) with the Original Factory configuration and it sees the second 250 GB SSD just fine..  It does show as Disk 0 in Disk Management and the M.2 drive goes to Disk 1.

One warning .. remove any SD card you have installed until after you have the second drive configured.
