no start with the sdb drive.  after you restore one of the superblocks try the assemble command and see if that works.

ok, you will have to do one disk at a time.  start with sdb. 

try to reassemble after you fix the superblock on sdb.  you may not have to do all the disks.  if that does not work then fix the superblocks on c and e and then try the reassemble command.  it will work eventually.

no it wont hurt anything, just shouldn't have any valid superblocks on it as it was never part of the RAID.  should be blank.

sdd should be blank from the formatting

dcerouter_1024641:/home/bruce# mdadm --stop /dev/md1
mdadm: stopped /dev/md1
dcerouter_1024641:/home/bruce# mdadm --assemble --force /dev/md1 /dev/sd[b,c,d,e,f]
mdadm: no recogniseable superblock on /dev/sdb
mdadm: /dev/sdb has no superblock - assembly aborted

you want    sudo fsck.ext3 -v /dev/sdb

do everything to /dev/sdb

If i am correct that is where the bad superblock was

make sure to run mdadm --stop /dev/md1  before anything

On second thought don't run fsck.  Backup your data once you get it running and then run fsck if you want to use that RAID.  Sometimes fsck will throw stuff in the lost and found folder.  Better to keep your organization the way it is for photos i am assuming.

Hey Beeker, sorry I haven't replied in a while.  I have been very busy at work and had no internet at the home.  If you still need to fix that RAID follow these instructions on this link for /dev/sdb.

first run this command just to be safe

mdadm --stop /dev/md1

then follow this
http://linuxexpresso.wordpress.com/2010/03/31/repair-a-broken-ext4-superblock-in-ubuntu/

your using ext3 i think?
Once you have replaced the bad superblock with a backup run


mdadm --assemble --force /dev/md1 /dev/sd[b,c,d,e,f] 


let me know if you have any problems
if you do get the RAID up and running again you will need to run fsck
but NOT until it is rebuilt and ready to use/online

ok, looks like you got f working again.  this is probably why the drive assignment changed and made me pee myself a little when you formatted d.  good stuff.  ok lets work on the superblocks.  gimme a couple to get the right strategy going.  working at the moment too.

and thats ok if the drives are still showing as removed.  we have a bad superblock to fix, I am assuming we will find some more but we will get to that in a bit.  gotta get those two things sorted first.

ah ok so we have d now but no f LOL.  maybe jiggled a wire loose?  and it looks like e is formatted for HPFS/NTFS.  UH, HPFS... o.0  what in the wild world of sports?  I have not seen that before!  That has got to be formatted first and we need /dev/sdf back.  I hope i just never noticed that linux reports NTFS as HPFS/NTFS.  HPFS has been dead since NT 4.0 came out.  Read quote from microsoft LOL!

Disadvantages of HPFS
Because of the overhead involved in HPFS, it is not a very efficient choice for a volume of under approximately 200 MB. In addition, with volumes larger than about 400 MB, there will be some performance degradation. You cannot set security on HPFS under Windows NT.

HPFS is only supported under Windows NT versions 3.1, 3.5, and 3.51. Windows NT 4.0 cannot access HPFS partitions.
