.dmg File Wouldnt Ope
If I were you I would ignore the dmg problem until you fix the higher priority problem of the disk errors. Maybe fixing that will fix the dmg problem and I'm guessing almost certainly the spinning cursors.
After downloading the Mac OSX SimUText installer file, the DMG fails to mount, or you see a second DMG file including the word, 'Part' Action: The installer DMG file did not fully download, the download was interrupted, or otherwise damaged. Download again and wait for the download to complete before opening the DMG file. As mentioned, a DMG file is an Apple version of a Windows ISO. A compressed file image that contains the files necessary for an OS X installation. It can also contain compressed program files too for a quick way to install a fully operational Mac or hackintosh machine. The best way to open a DMG file is on a Mac. If you want to install a program to your Mac OS, rather than use an ISO file, you would use a DMG file instead. Both an ISO and DMG file are filled with all the necessary installation files, like the installation wizard, to install a program to your computer, whether it’s Windows or Mac OS. You’ll also see these a lot with compressed files. Of course, if a DMG file is only supported by Mac OS then a Windows PC isn’t going to be able to open it.
As I understand it Lion drives are formatted with a special 'recovery partition' which takes the place of the separate bootable installation disks. It contains a copy of Disk Utility. Read the following on how to use this partition.

The best option, whenever possible, is using 7-Zip. You probably already have it if you're a Windows regular, since it's a free and convenient way of extracting the more universal ZIP format.
Once Z-7ip is installed, find the DMG file you want to work with in File Explorer and right-click on it. In this case we're using some of Apple's free system fonts as an example.
Mouse over '7-Zip' in the right-click menu, then select 'Extract Here' or 'Extract files.' That should give a choice of where to send extracted material, though by default the app will create a subfolder in your current File Explorer location. Click 'OK' once you've chosen a place.
.dmg File Won't Open
There's a good chance you'll have to dive into the new subfolder and run extraction again. With Apple's font DMGs for example, the real meat is buried within an HFS archive, which you'll need 7-Zip for. HFS is a filesystem used exclusively by Macs.
That should be it — you may see a lot of confusing folders and files, but what you want should be buried in there somewhere.
How To Open Dmg File On Mac
An alternative to 7-Zip is DMG Extractor. Though it's very straightforward we're inclined to recommend using 7-Zip as your first resort, since DMG Extractor has harsh limitations without a paid license. You can't extract more than 5 files from a DMG simultaneously, and it simply won't work with encrypted files or those bigger than 4 gigabytes.
