It appears that the hard drive in my array is not failing – or at least, not as bad as I expected. I’ve done two more scrubs the disk with no errors, or increases in the error counts. I’m still going to keep a careful eye on it, but I’ve got a window to breathe in. If I can swing it, I’m going to put some faster drives in my Mac, and move the 750’s in my Mac into the array as hot spares.

Mr Murphy may strike – posting this may force the drive to fail. We’ll see.
