RAID 5 failure after CMOS reset
Posted: 06 May 2012, 15:27
My CMOS was reset (system stored in move and CMOS battery died). Windows booted *before* I had a chance to set the BIOS back to [RAID]. I did not initialize or format any drives in Windows, and quickly disconnected the power. I rebooted and changed to RAID mode, but it had 2 of the drives as non-member
Raid was created on a ASUS Sabertooth X58 LGA 1366 with chipset Intel ICH10R.
1x1 TB OS Drive ((Windows 7 x64)
Intel Matrix Storage Manager ROM 8.0.0.1038 ICH10R wRAID5
3 x 1.5TB Raid 5
Note: in OS only partitioned a portion of the array to leave reserve space (I had originally provided 2TB and extended to 2.5 TB)
Just 1 drives correctly remains identified as "Member Disk." The 2 other drives were reset to "Non-Raid
I am following instructions found from: http://forums.extremeoverclocking.com/s ... ?p=3329132 which others have referred to as well.
1) Go into the Intel Matrix Storage Manager in BIOS.
2) Mark all the drives in the RAID as "non-Raid."
3) Re-Create the RAID using the SAME settings as the original RAID that you are trying to recover.
Since drives were not changed, I assumed the disk order was correct. I set the same configurations
Raid Name: Data
Raid type: RAID 5
Block Size: 128K
4) I ran testdisk and was able to analyze the disk, but selected the options attached in the screenshot
I selected INTEL instead of EPI-GPT even though they stated this was detected (Raid was created through the BIOS)
I let this run, however I am generating these errors for invalid FAT Boot Sector.
This should be correct since there is not an MBR. This quick scan is taking quite some time. I just want to verify I selected the correct options and let it run its course or do I need to select start over and select EPI GPT
Thanks in advance, I appreciate any help.
