7.04 (yes!) and large drives

[Karl Auer]

I have a 3TB drive in an Astone USB3.0 enclosure. The drive is seen, but
partitions (regardless of size and regardless of whether I use an MBR or
GUID partition table) cannot be mounted by Ubuntu 7.04 - it reports the
drive as being "very large", then a call to READ_CAPACITY16 fails. A bit
of googling suggests that this issue has long since been fixed, but I
wonder is there any workaround besides upgrading?

I have 1TB drives that ARE recognised. They are in Astone USB2.0
enclosures. If I put a 1TB drive in the new enclosure, it works. Putting
the 3TB new drive in an old enclosure kinda works, but ONLY if the drive
is formatted with MBR and contains a first partition of any size less
than 800GB. The drive is recognised as an "802GB HDD". Larger partitions
are seen and are even mountable, but things like e2fsck complain that
the partition is larger than the disk, and that something must be
corrupted. I'm not sure how safe it would be to proceed under those
circumstances.

For now, I've given up and am using 800GB of the drive because that's
better than nothing.

Any ideas as to what I might do to get more of the drive recognised and
mounted? Is it safe to use the drive when the drive parameters disagree
with the file system parameters?

Please don't suggest upgrading Ubuntu, that much I have figured out by
myself :-)

Regards, K.
