Have you tried forcing the start of the array with the --force flag?
Something like this:
mdadm -A --run /dev/md1
Please give the output of the command.
Lorac> What's the output of 'cat /proc/mdstat' and 'mdadm

Lorac> debian:~# cat /proc/mdstat
Lorac> Personalities : [raid1] [raid5]
Lorac> md1 : inactive hdh1[4] hdc1[0] hdg1[3] hdf1[2] hde1[1]
Lorac> 976791680 blocks
This is the key info, the array is assembled, but it hasn't been
started properly, probably because of the missing disk. Try the --run
args as above and see what it does for you.
See how it says 'inactive', this means you need to get it running
first.
Good luck,
John
