This comes from the identify data (bit 10 of the
cfs_enable_1/command_set_1 fields in drivers ide) indicate the drive has
an HPA so we try and read it. As there is no error report it seems the
drive replied fine and we turn it into a rather bizarre value, but all our
endian and the like code appears correct here.
Is your IDE controller LBA48 capable ?

We try and set the disk size to 185074430006016 sectors.. it objects
unsuprisingly to this proposal.
