3TB hard disk displayed as 746GB

Solution 1:

This problem is resolved in my 10 years old HP desktop (4 cores), with drive: 3TB Western Digital Green, but it should be the same with Seagate too.

• I added the solution to this blog: Post Anything Here.

In a nutshell you need 2 things to do:

• to install the Intel RAID driver (free).
• to use a good tool for extending the partition to the maximum size, like AOMEI Partition Assistant (freeware).

Cheers!

PS1: After all is setup property, you can uninstall both tools mentioned above.

PS2: If you have any conflict between the new 2TB or 3TB disk and the old DVD-ROM then disconnect the DVD, and get an external one (my case).

Solution 2:

At last, I found that I have to install Seagate DiskWizard to enable the full 3TB disk space.

Note: The software will erase all the contents of the 768GB.
