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