No, fakeraid does not know or care about the HPA. It still stores its metadata at the end of the disk, as it appears when its size is reduced by the HPA, if there is an HPA. Most systems do not have an HPA, but some quirky ones do. Both the bios and the Windows fakeraid drivers leave the HPA intact if the system bios saw fit to make one. A stock Linux kernel does the same, but Ubuntu kernels default to automatically unlocking the HPA, which moves the location of the fakeraid metadata relative to the end of the disk, so dmraid can not find it. Of course it also enables the user to write to an area of the disk that the bios very clearly marked as off limits. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
