Hummmmmmm..... Were the disks successfully added to the wrong array? Are they spares? Or are they in-use? What type of array is it? Like RAID5 or RAID1. Have you removed the disks from the wrong array? Does your RAIDTAB have? oersustebt-superblock 1 or persistent-superblock 1 If the wrong array is RAID5 and the disks are not spares, then some of the data was over-written. If the disks were just spares, then I think only the superblock was changed, if it had one! I will attempt help after you answer the questions.

Does it not make sense or is the answer so obvious that it doesn't deserve an answer. :) I appreciate any light someone can shed on this problem.
