Customers' requests revisited
The customer walks in and says something along the lines of you should have more input options for your RAID Recovery app.
Unfortunately, it just does not work that way. As you add more options and combinations thereof, people starting to get lost among these fast. Interestingly, I recall once considering an automatic software to detect all RAIDs attached to the system with just one click of button. Something more along the lines of All your RAID are belong to us, which would eliminate the requirements both to specify array type and to select a disk set. Just do all the probing and produce all possible RAIDs. Unfortunately, this did not work out for technical reasons.
Actually, even providing a correct RAID type may prove difficult if the array was created five years ago, the person setting up the system retired four years ago, and noone even noticed the RAID until it failed. So now you have four disks, some of which may or may not work; so, RAID 0, RAID 10, RAID 5, or RAID 6? OK, RAID 6 can typically be ruled out based on the controller model alone, but the rest may not be that easy.
