What methods of producing hard drive images stand out with regards to being platform independent and standing a good chance of usability in the future. Some considerations:
- Can the imaging program be run on a variety of OS, disk, paritition, and file system types?
- Can the image by mounted in place by a variety of OS's?
- Compression would be a plus, as well as actual files vs. bit for bit copying.
The motivation for my question is having old hard drives that I must hang onto and wanting to make sure that I have backups of them just in case as well as to use the images as an easier access mechanism versus actually having to hook them up to some computer with the disk's specific hardware interface. I also regularly use OS X, Linux, and Windows OS.
I've searched superuser and while there are similar questions, I don't see a duplicate that address these specific aspects of imaging hard drives. If I'm wrong, please add the appropriate link.
