Could someone using GPT on a BIOS system confirm if I got the GPT partitioning right on a BIOS system
I followed the documentation from http://www.rodsbooks.com/gdisk/ This is the out put after partitioning the HDD using Ubuntu 11.10 live CD root@ubuntu:/home/ubuntu# gdisk /dev/sda GPT fdisk (gdisk) version 0.6.14 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.

The util fdisk doesn't support GPT. Use GNU Parted. The device presents a logical sector size that is smaller than the physical sector size. Aligning to a physical sector (or optimal I/O) size boundary is recommended, or performance may be impacted.
