Neither are correct. The syntax changed since xl:
http://xenbits.xen.org/docs/unstable/misc/xl-disk-configuration.txt

It should be:
disk = [ target,format,vdev,access ]

in this order, or with key=value explicitly set each time:
disk = [ format=format, vdev=device, access=rw, target=/path/to/target ]
note: here target *must* be *last*

Prefixes such as "raw:", "qcow2:", "file:", "phy:" etc are all deprecated.

There was a time I was using 0x300 for hda, but I do not see any
reference to it in this documentation. There is this one also:
http://xenbits.xen.org/docs/unstable/misc/vbd-interface.txt

From what I understand the best is to use xvda xvdb etc when supported
by the guest.

HTH,
