Hi don't know if this is related to this bug but my Wheezy install on a
USB HDD recently stopped booting, the thread on Debian-User is here
http://lists.debian.org/debian-user/2012/05/msg01144.html
It gets as far as the grub> prompt and will boot if I enter
linux /vmlinuz root=/dev/sda1 ro
initrd /initrd.img
boot
I've tried various options to get grub working with no luck and I'm left
wondering if it has something to do with the drive appearing more than
once (3 times) in /dev/disk/by-id which my pen drive and USB SD card
reader both of which GRUB can boot off do not.
ls -la /dev/disk/by-id/

I have tried feeding all 3 entries into /boot/grub/device.map, at
install time grub chooses ata-ST1000LM010-9YH146_Z110VXRS
if I enter
(hd0) /dev/disk/by-id/scsi-SSeagatePortable
into /boot/grub/device.map grub-install /dev/sda works with no errors
but I still end up at grub> on reboot

There's output from bootinfoscript here

What debugging can I do? I tried coppying a squeeze install onto a USB
HDD and it wouldn't boot either, in fact it didn't make it to grub>
getting stuck at grub rescue>
Should I start a new bug report or is this one enough?
Thanks for any help.
