External HDD 3TB not recognised by DD 11
I have 2 Western Digital 2TB external HDDs and they are both recognised fine. I just added a 3TB version and Disk Director 11 does not see it. What can I do to make DD see the 3TB HDD?

Is there an Acronis tech on this forum? I really would like some feedback on my query please.

Hello Brian,
sorry for the delayed answer.
Acronis Disk Director 11 (all editions) does not support 3 TB hard disk drives.
Support of drives larger than 2 TB was added in Acronis Disk Director 12.
Please upgrade and check if it solves the problem. If it doesn't, please contact our support team.
Thank you.

Recently I got 3TB external disk, but DD12 does not recognize it! I use Disk Director 12(Build # 3223, Japanese)
You say "Support of drives larger than 2 TB was added in Acronis Disk Director 12.". Is it true for DD12?
The 3TB disk is recognized by Windows disk manager and other partion manager (AOMEI Partition Assistant Standard Edition 5.6), but not by DD.

Hi Kazuhiro,
please note that Acronis Disk Director supports only disks with 512 bytes logical sector size. If your disk has logical sector size which is not equal to 512 bytes Acronis Disk Director 12 won't be able to detect this disk and/or won't be able to perform any operation on this disk.
Please refer to this article for more details.
Thank you.
