How Are RAID Arrays Identified By Hardware?

Coward Anonymously Before Me asks: "This is more of a tech/hack question, but recently my highpoint controller forgot my disks were in a raid array. All the Disks still function, and have ZERO problems, aside from being not identified as still in RAID-0. All the data should still be there, but remains unaccessible to me, thus the question how and where would this kind of information be stored? On chip? MBR? and can the data be recovered without 3rd party interaction via free/open source toolkits? or even purchased software?"

...you ought to be able to just dd the data from the drive, and if the chip doesn't use a non-standard data layout, write a program or script to put it back together and back it up, then you recreate the array, and put your data back on it.
