Dynamic disk drive "missing"/"failed". Is there anyway to restore and recover the files?

Hi there,

I recently installed a 3TB seagate barracuda last week to my build. Upon initial install, only 2 TB were showing up, so I partitioned using GPT and was able to see get the full 2.7 TB to show. However, in disk management, they were showing up as two separate drives: one with 2TB and one with 0.7TB. Since, I wanted to consolidate under one drive letter instead of two, I made them into a dynamic drive. Everything seemed fine and dandy for the next week or so, until yesterday, the power to my house shut off briefly and when the computer rebooted, checkdisk started to run, and when I got to windows, my latest hard drive was no longer visible. In disk management, the 0.7tb portion shows up as missing/failed.

So far, I've tried:
1.) removing and reinstalling the cables to the hard drive
2.) Going into disk management to try and reactivate the volumes
3.) I ran SeaTools to scan for problems and it passed all of them
4.) I ran minitool partition recovery, however, the drives show up as "bad disk" and I can't go on further

Is there anyway that I can recover the drive/files? or am I S.O.L.? Also, here's a screenshot of what the diskmanagement shows: http://i.imgur.com/OS76u5X.jpg

Thank you in advance!

Have you tried right clicking on the partition and assigning a drive letter? You may need to just back up any critical data on the drive and repartition. You might also try resetting the BIOS to defaults or checking to make sure the UEFI and AHCI settings are still enabled and it's not running in legacy mode, which won't allow partitions over 2TB or dynamic drives. Only GPT partition tables will allow that and legacy modes run under MBR which you may have present on one of those drives as I see two instances of 101MB unallocated which generally indicates system partitions.

The option to assign drive letters is grayed out, I'm thinking because the volumes need to be reactivated. I tried restoring the BIOS to defaults as well. UEFI and AHCI settings are still enabled. I'm currently running a scan with Minitools Power Data Recovery. Let's see how it goes...
