Summary: The built-in backup software and user interface cannot be uninstalled or disabled on a Windows system and prevent the drive from functioning as a standard USB hard drive. Tends to keep my computer from booting successfully if it's connected - it somehow manages to keep setting itself higher in the boot priority list, to where the computer tries to boot from it instead of the internal hard drive.
Summary: My mistake! I bought this item thinking that I could simply use it for background backups of my data! It was on the shelf with other external drives and I mistakenly assumed that it would operate as one. I also assumed that Hitachi, being a well known company, would provide reasonable support! Like I said, my mistake...I won't make that one again.
