This is a corrupted disk, or perhaps the IDE driver is not installed
correctly.
the disk is fine, I can boot it natively. The hardware emulation in
qemu is very old (circa Pentium Pro CPUs). It's possible (probable, do
I remember LBA supports 120 Gbytes? wasn't there an earlier max of 32
Gbytes?) the disk (320 Gbytes) is larger than the emulation supports.
It's also possible that Windows is picking up garbage device geometry.
Ah, I haven't tried very large disks. I'll check it out.
Funnily enough, a change was just commited to the Xen's copy of the QEMU
ROMBIOS to support disks > 128 GB which I suspect would also apply to
upstream QEMU / KVM's rombios

The new limit should be 2TB.

Thanks, Dan, that's encouraging. When is (and is) this likely to filter
through to those of us who prefer to not patch their own software?
