I wonder what else could cause the out of disk message then.What does the partition table look like? It doesn't extend beyond sector 156312575 does it? Also I wonder about why H=16. It should be 255.
I didn't look at the code, but this is probably the ATA geometry of the disk, which is returned by the INT-13h (Extended) function 48h (Read Drive Parameters). If I remember correctly, this geometry is always 16383/16/63 for disks larger than 8.4GB. Grégoire
