The label will only exist if you gave it one and the type is correct, or
the same as mine at least.

TBH I have no idea what most of the things Palimpsest reports mean, I just
know if it reports errors on a drive it will fall apart on you quite
soon. Although a faulty cable can cause it to report errors as well.
There little to no documentation on Palimpsest and you have probably found
Help provides nothing.
As there is clearly a problem my only suggestion is to make sure you have
a decent backup of that partition. I would then run fsck on it, from a
live CD or if you have another Linux on the disk use that. The partition
must NOT be mounted when you run fsck. Or you could try creating another
/home partition, if you have the space, and see if Ubuntu boots OK then.
