Aurora R7, second internal hard drive not discoverable?!

Hello all,

I had recently bought an Alienware Aurora R7. I love the function of the desktop, however I can never use a second internal hard drive. I hooked them up to the SATA cable and the computer can not recognize this new 2TB SSHD. It does however recognize the hard drive if it is plugged in through a hard drive dock. I have searched the internet to no avail, Here is what I have tried:

  • Boot drive using secondary cables -- Boots up properly
  • Boot drive using primary cable and hook second hard drive up to additional internal sata cables -- Boots properly, but the secondary hard drive is not recognized. 
  • Boot drive using primary (or secondary) cables, using external dock for second hard drive -- Boots and recognized the second hard drive. 

 I am POSITIVE that the secondary cables are in functioning order as the boot drive can use these cables.

 

I really want to have this hard drive INSIDE the computer rather than using a dock (I am borrowing a friends). I have tried looking for settings in the BIOS and there is no such setting that has helped me thus far... Has anyone else dealt with this issue?

Not entirely clear what type of hard drive you're adding but SSHDs requires power. But did you connect both the sata data cable plus the power cable from the psu to the HDD?

Yes I did for the SSD. I am a little confused on why the SSHD needs power as it is a 2.5" Hard drive. It would not be a power issue as the SSD also has difficulty on connecting via the second hard drive slot. I did connect power and SATA cables.

 

If the SSHD does in fact require the power cable, then why do they only include data cables for secondary hard drives?

Power cables are specific to the PSU.  Non-modular PSUs like the 460W PSU included in the R7 have no connections on the PSU to add or remove power cables.  It doess have two spare 15 pin power cables for a HDD in the case behind the metal tab on the swinging arm.

I don't know what "SSHD" you bought, maybe you got a different type, but usually the basic concept is a spinning HDD (requires power to spin) + a nand/ssd component.  And yes, 2.5" SSDs require power too.  Only eSATA/usb, etc like what is used for an external hard drive enlosure supplies data + power to a hard drive as far as I know.

Advanced format drives require AHCI and F6 floppy mass storage drivers to SEE a drive.  You cannot point to the exe or zip file you have to extract the file to usb flash drive.  2.5 inch SSD's require BOTH 15 pin power and data cable.  This is true for all dell models.

You then have to boot windows 10 DVD or windows 10 PE and use diskpart to partition and format the drive.

Too funny.  l'm assuming by the lack of further responses that going back and plugging in the power cable solved the issue.
