Is it being recognized properly in the BIOS? Which port do you have it connected to?
If all looks well there, GPT should have done it for you, but check out some of the things near the end of this article relating to the driver. It could be playing a role. You're on W7 SP1, right? Are you using Intel RST?
Thanks for replying.
BIOS indicates it is 3000.5GB. It's connected to port 1 - 6Gb/s. UEFI in BIOS is enabled. When I follow the Windows site, and right click this drive, and choose 'Convert to MBR Disk', it switches to 746.52GB. I repeat for 'Convert to GPT Disk' it switched to 746.39GB.
Attached is a pic of the RST window.
I booted a 'Live' version of Ubuntu 11.04 and formatted the drive with a GUID Partition Table. Then, I created a partition (using the ENTIRE disk size). It formated OK, but gave me a warning message saying the partition was misaligned by 3072 bytes which could result in poor performance. It suggested repartitioning, but no matter what size I tried, I got some variant of 512 (3072 or 1536).
I ran a 'Read' performance test and the results were:
94.7 MB/s min
214.6 MB/s max
166.1 MB/s avg
Avg seek 14.7ms
Same test on the 500GB (boot) drive were:
49.0 MB/s min
112.3 MB/s max
82.6 MB/s avg
Avg seek 17.7ms
The boot drive is a 3Gb/s and the results are about half of the 3TB, so that makes sense.
Is this gonna give me trouble down the road? Anyone have any free windows disk performance tests I can try? The Linux program a used needed a completely BLANK disk to perform 'write' tests.
I re-booted into windows and the drive appears as a 2,794.52GB drive.
I responded on the Seagate board also.
I basically unhooked my boot disk and started a win7 install on the 3TB drive.
I had some problems when I got to the 'Format' stage. it showed up as 2 partitions - both unallocated:
Disk0 - 2048.0GB
Disk1 - 746.5GB
I couldn't delete either to make ONE larger space. I created a partition on the 2TB space. But I couldn't do anything with the 746 space. I deleted the 2TB partition. There was an error message indicating I couldn't install windows on either system. Something about EFI, although I'd enabled it in the BIOS. Anyway, after deleting and repartitioning a couple of times, It suddenly became ONE partition of 2794GB. I formatted it and hit the power button to kill the install.
I hooked my original win7 drive back up, re-booted and win7 now sees the D: drive as 2,794.30GB.
Thanks again all for replying.
It barely worked, but it worked, good!
Still curious about this though, I looked around a little more.
This article lays it at the feet of RST (even though RST itself shows the right size!), notably versions before 10.1, and most commenters agree, but you would have been using 10.8 or later, right? Still, since it's the exact same problem, RST is a suspect (perhaps the problem resurfaced in some versions since 10.1):
Interesting read. I'm also using an Intel (D)H67 mobo. I have the same version of RST too (10.0.0.1046).
I just finished using win7 'Error checking' under 'Properties' when you right click a drive and...Chkdsk found some bad sectors. Now, when I check the drive, it appears as 2794.30GB with 745.65GB FREE!!
I'm going to download RST 10.1.0.1008 and see if that clears this up
Seems the 10.1.0.1008 driver is for - 'RAID: Rapid Storage Technology Driver for Intel Desktop Boards'
Site says the latest for 'RST and AHCI Driver and GUI' is 10.0.0.1046
Wow. You might go with 10.8, which is a known quantity and solid, or 11.1, which they seem to have just posted despite the misleading date. Finding Intel drivers is a nightmare, since it's very difficult to get a bead on what the latest version of something is. Different pages will show different things. The page for your MB returns neither of the versions below but rather 11.0.
I'm pretty sure that's just incomplete phrasing. I know for sure that 10.8 isn't RAID-only since it's the one I'm using:
I'm going to download 10.8.0.1003.
What does this mean:
F6 and RAID BIOS configurations need to be performed prior to installation of this software for proper operation.
I'm starting to think I should have gone with Gigabyte or Asus. I also had trouble with this mobo's ethernet functioning through a switch. Straight from the router it's fine.
