Question about GPT HDD

I just ordered this HDD from Newegg yesterday: - HITACHI Deskstar H3IK30003272SW (0S03208) 3TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive

This is my current mobo: ASRock > Products > G43Twins-FullHD

Using openSUSE 11.4 x86_64 (no other OSes installed).

I’m aware that 4K HDDs require GPT partitioning. My question is: what should I know and what do I need to do so that the system/software recognizes this as a 3 TB HDD? Do I need to do anything? Will the system/YaST partitioning software “automatically see” the HDD as 3 TBs?

Not the 4K sector size requires GPT partitioning but the 3 TB size of the disk. I’ve never installed openSUSE on GUID partitioning except on Mac hardware but it doesn’t count, since I used MBR emulation. As far as I know - but it might have changed - only Grub2 supported booting from GPT. They might have added this feature to openSUSE Legacy Grub in the meantime, I don’t know. I would be interested in reading your report if you manage it.

Oops, that is what I meant.

I forgot to mention that is HDD is NOT for booting/installing the OS. It will only be for storage so this still doesn’t answer my question.

Oh, that should make things easier then since the Linux kernel supports GPT. It is/used to be only a problem for booting. I don’t know how the YaST partitioner deals with GPT. But I would say it doesn’t hurt to try on a blank HD.

Maybe this article might give you a clue: Make the most of large drives with GPT and Linux

Thanks, I’ll give that a read.

Well, I read the article. I checked YaST’s partitioner and it indeed does have the option to create new partition tables with GPT, so I think I should be fine.
