Hmmm... You might have won the lottery, statiscally speaking. I think I 
remember a similar issue although and as I kept on putting new drives into 
a linux software RAID1 array, they all kept on failling almost together.

I ain't saying this is what is happening here and I wish it isn't. But 
just keep a close eye on that SATA controller if you see similarities with what 
I experienced.

I am experiencing a problem right now where newer NIC cards don't seem to 
play well with older hardware. I always try to factor in everything so maybe 
we could draw common points with HD controller errors.

Long live your new drives although,

How much space do you need for one snapshot? I got a rsync incremental 
backup scheme going so maybe I could contribute on that level depending on 
space requirements.

As far as too many eggs in a broken basket I have experienced that 
also. As far as no signs, it might sound like HD controller. Then 
again, I hope I am wrong.

I have a fast link to restore if I can contribute.

Thanks for the great job!
