Maybe you thought it would be in the support file I keep for you? When people offer suggestions they (or at least I) will probably form a picture of what's going on - if you are going to throw tweaks into the mix then they may throw us off. Mention them. You have failed to answer some potentially relevant questions and, before you get this array rebuilt you wandered off (on the same thread) into discussions about what disk drives you might like to buy, the best type of external enclosure and various other oddments. This is not helpful. >The correct information should already be in /dev/sdg1 since I copied the entire >/dev/sda there (probably overwrote stuff in /dev/sdg2 since /dev/sda was 160K >bigger than /dev/sdg1). Err, no. Linux doesn't randomly overwrite other partitions... You're on 0.9 superblocks which are located at the end of the disk. I *think* your assemble problem is that /dev/sdg1 was an old component (slot 6); it had a superblock near the end of the partition which you didn't zero. You copied most of /dev/sda into it but you made /dev/sdg1 too small by a few k. The copy finished before it copied the /dev/sda superblock (I don't know why it didn't overwrite the old superblock??). Also, at some point, md will try and seek past the end of /dev/sdg1 and will die. You have now dug a maze of twisty passages... I think at this point you should enlarge /dev/sdg1, recopy /dev/sda to /dev/sdg1 and try again. That will probably work.
