Alienware 15 Hard Drive not displaying and long boot time

Good day,

I've have a Dell Alienware 15.  Recently my 1TB hard drive has stopped appearing in windows and dell support assist.  It appears as though it isn't there, even though it appears when I check the BIOS.  In addition, my boot time has increased as well since this happened.

Windows does still start, and my SSD does appear and allow me to accomplish my day to day work without incident, but if possible I would like to get my hard drive back without replacing it.

I've tried the steps lain out in an article I found elsewhere in the forum (link below) which advised flashing the BIOS and running  Dell Enhanced Pre-Boot System Diagnostics (ePSA).  Neither of these have worked.

I flashed my BIOS to A08 using the dell website auto detect function.  After my laptop rebooted post flash, it started with automatic repair, and it took several boot attempts to get it running.  The BIOS says it is version A08 though, and I don't know enough about BIOS to try messing with it.

The ePSA diagnostic ran for about 45 minutes for the initial scan, and than about 3 and 1/2 hours for the extended memory scan.  It reported that there were no problems.

I would appreciate any advice anybody has on my situation.  If I need to provide more information, please let me know.
