I never said anything about disk RAIDs and backups. They are solutions that have different applications. I was simply trying to offer the OP some information that he could actually use where his disk failures are concerned.
If you like, however, I can take the topic further off course by going on and on about how some RAID devices are also backup devices, such as VTLs, or how some SANs are used as backup devices, or how you can recover data from a RAID1 member on a different system. I have 29 years of technical experience, work as a IT solution architect, and see this stuff every day. I know there are a lot people on Head-Fi that are technical professionals. Perhaps you are one of them.
But us getting into a technical tit-for-tat about RAIDs and VTLs is not going to help the OP one bit. Neither is suggesting that a software magic bullet might solve his problem. No one here has enough information about the precise nature of the problem to know whether or not software recovery is possible.
I know if I took what I thought was a failed drive to someone who ostensibly was a specialist in data recovery then I would expect much more information from them besides "the disk is toast." That's like paying someone to tell you something you already know. Imagine turning the key in the ignition of your car and nothing happens. You take it to a mechanic and he tells you "the car won't start."
Companies such as DTIdata have a properly equipped clean room, and if necessary they can crack the drive open and get to the disk media (where all of your data lives) and recover it. I am not trying to plug them specifically, there are dozens of firms that provide similar services. I don't know what DTIdata's service costs. Some outfits charge by the gigabyte, some charge by the size of the logical volume, and others charge by the size of the physical disk.
To the OP...
Check your drives for a clicking noise as I suggested. If you can hear it then you already know there is a problem with the heads and the disk will need to go to a data recovery specialist such as DTIdata if you want your data back. If you still have both disks -- the failed primary disk and the backup disk, then you might want to send them both in and see if one of them can be recovered. Most of these places will only charge you for what they can recover.
It never hurts to get a quote. The worst that can happen is they give you a price that you don't like and can't accept, and you are no worse off than you are now.
Some information we don't have that might be helpful:
1. Does the drive spin up when power is applied?
2. Does the computer detect the presence of the disk when it is connected to the system?
