Added SATA hard drive showing up as /dev/hdc

I added an additional hard drive (1.5 TB WD EARS drive, the one where you have to put the jumper over pins 7 & 8, at least according to what I've read on these forums).


All of my previous drives have been going to /dev/sd* - but this one decided to be /dev/hdc.  I do have one other device that's /dev/hdd and that's my cache drive which is connected via IDE, all the other drives are SATA.  Isn't that what determines if it's sd or hd - if it's via SATA or IDE?  Is the fact that this new disk showed up as HD something for concern?


Here's my disks (as shown by unmenu):

My syslog (fresh boot from when I added the drive) is attached.  Any advice or corrections to my understanding would be much appreciated!

It is because you've set your BIOS to have it emulate an IDE drive.


Set the BIOS to AHCI and it will show properly.

That was indeed the problem - thanks!


Interestingly enough, all the sata ports were set to IDE instead of AHCI, but only the final two were actually coming up as IDE.
