Comment 1 for bug 430333

I'm learning grub's CLI now. Getting some cues from grub bug (DebianBug#430333) for things to try...

rescue:grub> probe -f hd0,1
ext2

    [shouldn't that say ext4?]

probe -d hd0,1
biosdisk

probe -p hd0,1
part_msdos

probe -u hd0,1
e88f90e1-950e-f0f6-947a-4baa97945122

----SO it's reporting ext2 instead of ext4, and acting as if it cannot read anything on the disk.
Booting again from the USB stick... going into parted:

$ sudo parted /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print

Model: ATA Patriot Memory 3 (scsi)
Disk /dev/sda: 32.3GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system flags
1 32.3kB 30.9GB 30.9GB primary ext4 boot
2 30.9GB 32.3GB 1374MB extended
5 30.9GB 32.3GB 1374MB logical linux-swap(new)

(parted)

The partition table looks OK to me, but what do I know? I don't know why it starts at 32.3kB, and I don't know what (new) means after linux-swap. But it does say the first partition is ext4, and Ubuntu NBR live (from the USB stick) can mount the partition (after about a 15-second delay).

Is this a grub issue? Maybe it doesn't have a driver it needs to read this sort of drive as ext4?

Let me know if there's anything else needed to debug this. Fortunately it's not my primary machine so I'll leave it broken for a few days.
