I don't know. Things are a bit weird now. I get this:

sudo mdadm --detail /dev/md1
sudo: timestamp too far in the future: Mar  9 23:07:44 2008

I have not idea what that means but that tie is wrong. It's only 5pm at the
moment.

I do still get the /sbin/init when trying to boot. However, I no longer seem
to have an active RAID device.

cat /proc/mdstat
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4]
[raid10]
md1 : inactive sda2[0](S)
      19534976 blocks

md0 : inactive sda1[0](S)
      291017344 blocks

unused devices: <none>

I may have made things worse. I decided that since this wasn't working that
I would install hardy on the second drive (the one doing the mirroring. It
worked fine but I no longer see any md devices when doing fdisk -l but they
still show up as raid

Disk /dev/sda: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

autodetect
/dev/sda3           38663       38913     2016157+  82  Linux swap / Solaris

Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000b02b7

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       36230   291017443+  fd  Linux raid
autodetect
/dev/sdb2           36231       38662    19535040   fd  Linux raid
autodetect
/dev/sdb3           38663       38913     2016157+  82  Linux swap / Solaris

I'm not sure how much effort this warrant anymore. It would be nice to know
why it didn't work or why it broke but I think I'm done with raid for a
while. I guess it's not that good of a backup tool anyway and that is really
I wanted it for.

Thanks for the help.
