DD 11 b 11.0.2343 does not see last tB on 3 tB drive Windows 7 64 bit

Is it an internal drive or a USB drive?

Can you post a screenshot of what DD shows and what Disk Management shows?

Does it show up correctly when you boot to the DD CD?

Thanks for responding.

My drive is an internal HDD. Hitachi 3 tB

I have no CD to boot from. I dl DD from the website.

Enclosed is a screen shot of the DD graphic. It lists (disk 3) the HDD as 2700 gB. I don't know what happened to the other 300 gB. At any rate DD does not find the last 1 tB even as unallocated space.

Thanks again,

Tom Rubens

The 2.7TB size is correct for a 3TB drive. You probably need to change the disk to GPT to be able to use all the space.

What does Disk Management show?

I am using NTFS. If 2700 gB is all I get then that is all I get.

What does Disk Management show?

Please see attachment on my last message.

Your previous attachment is what DD shows, not what Disk Management shows.

GPT is not a partition format (like NTFS). It's a disk type (like MBR). Large drives are limited when used as MBR disks.

I did some reading. Very interesting stuff. I was concerned that I didn't get it all but Acronis made the job of switching from MBR to GPT a snap.

Thanks,

I went to install Windows 7 64 bit on one of the GPT partitions. Windows objected. As best I can figure out Windows will install on a GPT partition if the computer has UEFI. I thought that Acronis partioning would take care of this. Aparently UEFI is firm ware that must come with the motherboard. Am I correct? Is UEFI something I can install? My system is an ASUS P6X58D-e using Intel Core i7 940 cpu.

Thanks,

If mobo supports UEFI, then somewhere in the bios setup there is a switch to boot in UEFI mode or in BIOS emulation mode. P6X58D-e apparently doesn't. Btw, ADD 11 doesn't support UEFI - it works with data-only GPT disks, but operations with the system GPT disk may render it non-bootable.
