Firstly I booted from a Knoppix CD (2.6.19) and it sees the partitions just fine. Then I looked in /var/log/kern.log (previously I had been looking in dmesg) and found:-
hda: Host Protected Area detected. ^Icurrent capacity is 268435455 sectors (137438 MB) ^Inative capacity is 312581808 sectors (160041 MB) hda: 268435455 sectors (137438 MB) w/8192KiB Cache, CHS=16709/255/63 hda: cache flushes supported hda: hda1 hda2 < > hda: p1 size 302343237 exceeds device capacity, enabling native capacity hda: detected capacity change from 137438952960 to 160041885696 which obviously did not used to happen with the Knoppix kernel, or the older 2.6.26 kernel I ran from this disk before. Anyone know what this Host Protected Area and what I do with it and how I make it detect the disk properly?
