| |
Hi, . I want to remove HPA in SATA, I was recommended to follow this linux-ide site. http://www.mail-archive.com/linux-lde@vger.kernel.org/msg05215.html I want to remove HPA area under Kernel-2.6.18. But after patching ,I couldn't see anything like HPA in dmesg and fdisk information. There is no difference between before and after patch. Now I am using SATA 250GB includes HPA, 11GB. And I installed HDPARM7.3,which support SATA, to get some information. But there's nothing related to my SATA 250GB, HPA. In the output of "HDPARM -I /dev/sda" there is a device size, 239GB, but that doesn't include HPA area. Could you please tell me which kernel patch, program or commands to use in order to remove HPA area under Linux ? .......................
