Turned SATA mode to AHCI from RAID, then switched back and RAID0 Failed

post #1 of 4
Thread Starter 
So I went to update the firmware on my kingston SSD's which can only be done in AHCI mode. So I switched sata operation to AHCI from RAID, booted to windows, did the firmware update, then switched back to RAID mode and now it's saying my RAID0 array has failed. So I'm not exactly sure what happened or what to do.

This thread here says to delete the volume and create it with the same name, but that seems to risky:http://www.tomshardware.com/forum/24...r-raid-failure

I found this guide as well: http://spench.net/drupal/resources/raid0/restore

I don't think the array really failed, I just think that when I booted into windows it rewrote the MBR of the "drive".

Does anyone have any thoughts? I'm about to try running testdisk to see if it can recover drive structure.

Alright well I solved the problem, if anyone comes here looking for the solution, here's what I did:
  1. Deleted RAID0 array in intel storage manager and recreated it with same settings and names. This essentially replaces the metadata on the drive but creates a new partition table
  2. Booted into windows and used testdisk to analyze the current partition structure. Even though mine is a 4TB GPT array, the intel/PC option is what found stuff
  3. Analyse found a partition, but not the partition. Hit stop. Then deeper search. Within a couple seconds my partition came up. I verified by hitting 'p' so I could view the files.
  4. I then changed it's option from D (which means it was deleted) to * (which means it's primary bootable) by hitting the left/right arrow keys
  5. Restarted computer to apply MBR changes. Drive still shows that there isn't a file system or it's corrupt / damaged. Go back into testdisk
  6. Hit file system tools -> then it will show the current partitions. 'Boot' is selected by default in the bottom. Hit enter
  7. There it will show you an error, so hit rebuild BS and it will repair everything.
  8. Restart computer
  9. From there I had all my data back, however it still had issues with the partition size. Said it was only 2TB out of my 4TB. So I booted to GParted and expanded the array to the 4TB size and everything was good to go

I have a similar issue to this but I'm too afraid to recreate the raid as I'm not too savvy and might lose all hope of recovering my data
