Unable To Create Dmg Error 61

Trying to create the dmg image failed with the following error: Unable to create 'Macintosh HD.dmg'. (Input / output error) Tried it again selecting the hard drive instead of. The Mac that the PowerBook G4 is connected to is very slow, but is presently creating a.dmg image of it's harddrive and I was just wondering if this would prove to be worth it, as it appears to be take a day or two to create the image uncompressed. Oct 28, 2013 Right now I have the 10.9 installer sitting on my computer, so I'm ready to do whatever I have to do to achieve my former setup for Mavericks. I want to create a single.dmg install file that I can use to restore a disk and create a bootable USB drive at will. How can I achieve this?

I ran into an interesting macOS error while working with a customer a couple of weeks ago. I didn't find a lot of good search results addressing the issue, so I decided to write up a post about it myself.

Create Dmg On Windows

The error was as the screenshot above shows; trying to open a dmg (disk image), macOS showed the error 'no mountable file systems'. If you see the 'no mountable file systems error' while opening a dmg, here's what you should try:

  1. In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. You can try downloading the file in a different browser as well. Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try curl -O url in Terminal to download the file. (There's an example of that in my screenshot below.)

  2. Reboot your Mac if you haven't already tried that. Apparently there is an issue sometimes after opening too many dmg files, that is fixed with a reboot.

  3. Try mounting the DMG on the command line in Terminal. We will at least get some sort of useful error message to go on if it still fails:

    • Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.

    • Type hdiutil attach -verbose into the terminal. Add a space at the end, but don't press enter yet.

    • Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window.

    • Press enter.
  4. macOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). So if you're on macOS Sierra (10.12) or earlier and you ran hdiutil and see references to Apple_APFS or error 112, the issue is likely legitimate incompatibility, and this disk image won't open on this Mac without an update to the operating system.

    Here's an example of the end of hdiutil attach -verbose output that shows an APFS error due to an older version of macOS:

  5. Download os x dmg macdrug. Think about if you have any kind of security policies on this machine to prevent writing to external drives (thumb drives, optical drives, etc). I haven't seen this one in action, but I read about this being a possibility while researching the issue.

  6. Another suggestion added by a reader (thank you, Markus!) is that filesystem errors on your main Mac drive could be the cause of the disk image mounting errors. Here are instructions from Apple for scanning and repairing errors using Disk Utility. Note that in order to scan and repair errors on your main Macintosh HD drive, you'll need to reboot your Mac into recovery mode. You'll want to choose Disk Utility in the utilities listed in the recovery mode menu.

  7. A new discovery from a reader (thank you, Colby!) is that APFS DMGs won't mount if you're booted in macOS booted in Safe Mode. (Who knew!?!) If you're not sure if you're in safe mode, select the Apple menu  > About This Mac > System Report button, then select the 'Software' heading from the left column. To exit safe mode, restart your Mac, without holding Shift during startup. Or, if you previously set your Mac to always boot into safe mode using nvram, turn off safe mode and have your Mac boot normally on the terminal:

    • Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.

    • Type/paste sudo nvram boot-args=' and press enter.

      Apr 03, 2018  Sneak attack damage can be specified as non-lethal. I rule that the nature of a sneak attack is precision in inflicting damage, thus assuming the character inflicting the damage has enough knowledge to know what will hurt vs. What will kill. The only exception for this is if the attack roll crits. Non lethal dmg dnd 5e. First, a note: there is no such thing as 'non-lethal damage' in 5e. Instead there is a rule called 'knocking a creature out' which is the only way to do damage without killing a creature that the rules provide. Sometimes an attacker wants to incapacitate a foe, rather than deal a killing blow. You can use a melee weapon that deals lethal damage to deal nonlethal damage instead, but you take a –4 penalty on your attack roll. Lethal Damage with a Weapon that Deals Nonlethal Damage. You can use a weapon that deals nonlethal damage, including an unarmed strike, to deal lethal damage instead, but you take a –4 penalty on your attack roll. Non-lethal weapon attacks now impose a -4 penalty and deal 50% normal damage, of which 50% is temporary. Rules are also introduced for unarmed punching, wrestling, and overbearing. Unique to this edition is a subjective limitation on which weapons may deal nonlethal damage: only bludgeoning weapons or those where an attacker can use the flat of a blade may be used nonlethally.

    • Restart your Mac.
