Windows 7: 16 TB RAID 5 Array No Longer Recognized

[SOLVED] 16 TB RAID 5 Array No Longer Recognized

SOLUTION:
Apparently using this external array in USB mode caused a major NTFS problem to be hidden
The drive was being actually recognized but the errors caused the system to hang for approximately 10 mins before allowing me to access the drive. So attaching the drive using ESATA, waiting 10 mins to recognize the drive and performing a chkdsk repaired the issue.

RAID: Standalone Hardware Raid Enclosure
TowerRAID TR5UT+B - 5 Bay USB 3.0 / eSATA Hardware RAID 5 Tower w/ 6G PCIe 2.0 HBA (Black)

Raid Level: 5

Hardware:
Drives : 5x Western Digital RE WD3000FYYZ 3TB
Operating System : Windows 7 Pro
Memory : 16 gb 1600mhz
Processor : 3.3 ghz AMD 1100T
Motherboard : Crosshair IV Extreme
GPU : MSI Radeon HD 7970 Lightning Edition
PSU : 1200 Watt Corsair AX1200i 80plus platinum
GPT Type

Symptoms:
After a circuit breaker trip, Windows 7 freezes when attempting to recognize the drive when it is attached.
It locks up until I unplug or power off the drive. Prior to sudden power loss drive was accessible.
When I unplug or power off drive Windows says drive is not formatted

Environment:
No UPS
Drive is connected to a surge protector and a GFI outlet
When power outage occurs GFI outlet will trip disabling power to outlet until reset by hand
(This prevents sudden surges when power is restored)
Drive temp are normal 30c

Trouble shooting steps:
Windows SFC - No change Problem exists
Complete OS reformat - No change Problem exists
BIOS Reset - No change Problem exists
Tried connecting with USB 3 / USB 3 / ESATA - No change Problem exists
Boot to Windows 7 PRO DVD - DVD also freezes when attempting to access drive
CHKDSK /f from Windows 7 PRO boot DVD - Reports drive as RAW
Windows 8.1 PE DVD - Can access drive and files No problem
Terabyte Unlimited Image for Lunix - Can access drive and files No problem
CHKDSK /f using Windows 8.1 PE DVD - NO ERRORS FOUND
Acronis Disk Director 11 - Recognizes drive No problem
Other USB devices work
Other ESATA / SATA devices work
Windows 10 PRO Install DVD Recognizes Drive no problem
CHKDSK /f from windows 10 Pro install DVD NO ERRORS FOUND
Lights on RAID do not indicate any abnormal condition (Array is not rebuilding)
I've tried giving it the finger and I've tried calling it obscene language
Both verbal and gestural persuasions have proven ineffective

Thank you for taking your time to look at this and for any advice that anyone could provide is greatly appreciated. I am attempting to solve this without a backup and reformat

DO you have a System Restore point from before the issue? You could try restoring back.

You can also try:
- A clean startup - Troubleshoot Application Conflicts by Performing a Clean Startup
- DriveCleanup
Quote:
- Manually create a System Restore point - System Restore
- Uninstall and remove the printer from problem PC
- Restart
- Run DriveCleanup as admin - Drive Tools for Windows down the page a bit
- Restart
- Scan with CCleaner for files and registry
- Restart

** DriveCleanup will remove all drivers for non-existent hardware, for example you will see external drives install their drivers when you next use them. If you get issues, restore the system back to the point you created initially.
