when you initialize the drive you must use GPT and NOT MBR if you want the full capacity.

Click your windows key button on your keyboard, then type disk management is your drive shown here? If so delete the partitions and then create a new partition and then format the drive.&nbsp;
</div>


<div>
it seems that the disk director version is different; so that can be the cause, but also the disk itself can be bad, or the usb cable/interface<br>i assume that both are USB drives ? or are they internal ?
</div>


<div>
Does your Windows Disk Management see this drive?

I have two Western Digital 4tb drives. &nbsp;They are shipped with stripped down versions of Acronis backup software. &nbsp;I wanted to remove this backup software by formatting the drives and use my Acronis 2020 backup software instead. &nbsp;I connected one of the drives to Windows 7 laptop and began formatting the &nbsp;drive with Acronis Disk Director 12.0 &nbsp;When it got to halfway, ie 2tbs, it failed. &nbsp;I could not label the volume and no computer would see it!<br />
<br />
I then installed the latest version of Acronis Disk Director 12.5 and successfully formatted my second WD 4tb drive. &nbsp;<br />
<br />
Now, please tell me how I can format the first drive that now no computer sees it!!<br />

Drive Not Visible to Computer

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
