On a new installation of Ubuntu Server 13.10, I'm having problems setting up Seagate 4Tb desktop drive.

When connecting it via either the internatl SATAIII 6Gbs or SATAII 3Gbs connectors on the motherboard, the drive does not show up when I run BLKID. However, the drive does show up using FDISK -l but with issues since it says it does not support GPT disks - but at least it shows that the system is seeing the drive. It gives it a logical location (sdd1) but I can't mount to that at all.

However, when I connect the drive via a SATA-to-USB3 converter and plug it into one of the USB3 ports, Ubuntu picks up the drive perfectly with no hassles. Shows up fined in BLKID and mounts with no problems.

Can anybody think of a reason why I can use the drive in USB3, but not SATA?

What do I need to do to get it to recognise the drive via a SATA connection?
 
Thanks for the suggestion: I thought that might be the problem originally, but further searches revealed thatn apparently Ubuntu 13.10 does have GPT support in the kernel. And also, since it recognises the drive perfectly via a USB3 connection, it doesn't seem to be the GPT support that is the problem.

Any other ideas?
 
When it is connected internally, and you try to mount it, what does the dmesg log and normal syslog logs have in them?
 
Most Linux distros for the last decade has had GPT support. fdisk, however, does *not* have GPT support, and probably never will.

if the USB enclosure picks it up, it might be that your on-bard controllers don't support discs larger than 2TB (or whatever the hurdle is). Try parted:

Code: 
parted /dev/sdd print

Try this on both the internal SATA ports and the USB enclosure, and compare the output. Check if it sees the entire 4TB space.

I have the other way around problem, my USB enclosure picks up my 3TB drive but reports it as 800GB. Thankfully my internal ports sees the drive fine.
 
Check if your BIOS support 4TB disks. It might need a new firmware version.
 
Use gparted and remove the MS Dos partition Table and replace with one that supports > 3TB
 
+1 for BIOS
&
+1 for parted

Those are the steps required to get this to work. Also make sure there are no limits in the kernel your using O.o
