Advanced Format drive

please guys, i just got myself seagate Momentus XT 500GB and i want to know if is there a way to tell if my new HDD is an Advanced Format drive.
when i do fdisk -l i got:

Re: Advanced Format drive

if you have a filesystem defined on the drive...

run:

Code:
fdisk -l /dev/sdX1

(sdX1 is device identifier, like sda1, sdb1, etc...)
If it's NOT an advanced format drive, it will look something like this:

Code:
Disk /dev/sdi: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x3132f6ca

   Device Boot      Start         End      Blocks   Id  System
/dev/sdi1               1  3907029167  1953514583+  ee  GPT
If it IS an advanced format drive it will look like this:

Code:
Disk /dev/sdj: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0xfc89fc8a

   Device Boot      Start         End      Blocks   Id  System
/dev/sdj1               1  3907029167  1953514583+  ee  GPT
Notice the difference on the line that has Sector size (logical/physical)? (The drive I have still reports to the OS as having 512 byte sectors, but it has 4096 byte physical sectors, like most of the advanced format drives are doing currently)

I don't think the Seagate Momentus XT drives are advanced format, though. Aren't those drives the "hybrid" drive? in between the standard platter drives and true SSD drives?
