Does Archlinux support hard drives with more than 2^32 sectors?

Slightly relevant to this:

https://bbs.archlinux.org/viewtopic.php?id=114977

I have change my mind, for various reasons, and I am thnking to go for this drive:

Seagate Barracuda XT ST33000651AS 3TB

http://www.seagate.com/www/en-us/produc … racuda_xt/

According to its specifications, it has:

- both physical and logical sectors of "normal" size (ie 512 bytes)
- more than 2^32 sectors (5,860,533,168)

So here are the rest of the data, and the question I have:

- I want to use it with Archlinux x86_64
- I do not want to boot from it
- It will only function as a secondary drive only for data storage
- The motherboard it will be connected has a classic BIOS - not UEFI.
- The disk controller on the motherboard is an nVidia 8200 chipset.
- I will partition the disk with gdisk.
- I will create a GUID partition table on it.
- I will make the whole disk a single partition.
- It will be part of an lvm2 volume group.
- On top of the lvm2 group, an ext4 filesystem will be created.

And here is the question:

Will I have any problems, or everything will go smoothly?


PS: I have read and understood the following relevant Archwiki article:

Re: Does Archlinux support hard drives with more than 2^32 sectors?

From Wikipedia - GPT allows for a maximum disk and partition size of 9.4 ZB (9.4 × 1021 bytes)[1][2] or 8 ZiB−512 bytes (9,444,732,965,739,290,426,880 bytes or 18,446,744,073,709,551,615 (2^64−1) sectors × 512 bytes per sector).

All modern OS and partitioning tools support >2^32 sectors if you are using GPT partitioning.

And Please Don't Cross-Post. You could have simply mentioned your change of preference instead of repeating the first post again.
