When I use Disk Utility to create an image, it gives me five options:
- Read only
- DVD/CD Master
- Hybrid Image
Most of these make sense to me why someone would prefer one option over another option, except for Compressed. I tested it out and the Compressed option made my image nearly half the size of the uncompressed version, which is great.
Now, I don't know for sure by I am assuming that this Compressed format is either Read only or Read/Write and if this is the case, why would you ever choose one of those formats over Compressed?
I did not experience any loss of data when I did the Compressed and given the significantly smaller file size it seems like a no-brainer to always choose Compressed. Maybe I am making some wrong assumptions here...
