Raid Drive recovery
-
If they are mirrored, try R-Studio. It's inexpensive and there is a trial you can use.
If you need further help I do data recovery.

50 cent backplane and/or 50 cent powersupply dies, so does 6TB of data.
@scottalanmiller Is hw RAID not an industry standard? Thinking about it i guess that has always been a problem. In HW RAID recovery you generally need the same raid chip manufacturer or card model if your card dies. Same with Fake RAID on mobos. -
Doesn't matter what HW writes the data... it's NTFS or HFS, Ext?, etc.
No one is writing their own file systems just to do RAID.

What they mean is that you can't "import" that G-RAID Studio RAID1 into a DELL PERC configuration, or vice versa. Different hardware RAID does RAID configuration differently.

Using hardware RAID is a standard in the commodity hardware portion of the industry.
The hardware itself, however, is not a standard except within a single vendor.
Example: Nearly all Adaptec cards can read drives from other Adaptec cards of the same era and firmware updates.
Example 2: Nearly all LSI cards can read drives from other LSI cards of teh same era and firmware updates.
Example 3: No Adaptec card can read a drive formatted under LSI or vice versa.

More than you might think. LSI doesn't even do RAID 10, it only does RAID 100. Adaptec doesn't do RAID 100, only RAID 10.
Adaptec does RAID 1 with 3+ mirrors. LSI does not.
Stuff like that.

Not exactly a filesystem, but they nearly all write something akin to a filesystem just to do RAID. The "format on disk" is unique whether it is ZFS, MD RAID, LSI, Adaptec, etc. They all look different when you look at the disk itself.

@scottalanmiller Not from a data recovery standpoint in a RAID 1. Other RAID's yes, but not RAID 1

I called G-RAID, and you guys are dead on. The new devices have a different hardware RAID controller, so I would have to find an old enclosure on ebay, or pay out for data recovery. I was lucky enough to find a copy of the 1 important piece of development that wasn't super out of date, so I have given up on the drive and the data. I will just move on from here. Thanks for the advice and lesson learned.

Have you downloaded R-Studio?

Yes, the - is important!

Even RAID 1 generally have some formatting on the disk so that the system knows what is there. It's minor and tools can often recovery easily as the filesystems are not obfuscated. But it's still there.
-
For recovery it doesn't matter. A tool like R-Studio can read it very easily.

I was going to before I found a backup of the Website I needed to restore. I ended up spending my limited time bring the old code up to date instead of testing the software. Thanks for suggestion.
