I would recommend Active@ Disk Editor as it is freeware Windows and Linux and in my opinion a better all around tool then Acronis due to many useful features. It meets most of your requirements along with some very useful features without being cluttered. Very similar to Acronis Disk Editor it is a powerful hard drive raw hex editor which shows your current sector and offset as well as having the ability to goto any location on the disk and find locations by searching for ANSI, Hex, or Unicode strings.

It also supports location bookmarks, drive and partition table formatted data templates to format data as well as tools for recognizing partition tables, MBR, file headers and much more.

I am no way affiliated with any company, I was just looking for a similar tool and found this along with your question during my search.
