More and more people are finding themselves using both Macs and Windows based PCs. While compatibility is almost a non-issue now days between Macs and PCs, as well as Macs and third party peripherals, there is one area that may still cause confusion. In this tutorial I will explain the “Read Only” error you may run into while using external storage devices, and also show you how simple it is to fix.

The Cause of 'Read Only' Disk Errors

Sep 25, 2012  Sometimes you may want to download and mount DMG file using Mac OS command line, and in this post I'll show you how to do it. Why would you want to mount DMG files manually? I've been business traveling quite a bit lately which means I'm most of the time away from my home computer. How can I delete files on a read-only file system? I have an encrypted.dmg file with some useless files that I need to delete to make space. How can I delete them without having to convert them into a read write system and then back? (Would take 45 hours). Like I said, it's read only so sudo rm -rf tells me that It can't delete it due to. How to compress and uncompress files and folders in macOS via the Terminal/command line using zip, tar.gz, tar.bz2 and dmg formats. Read-only image. I made a bootable USB using the Disk Utility, which can be done by first erasing the USB and giving it a format for Mac OS Extended (Journaled) and then in EditionRestoreRestore From, I selected the OSX Base System that appears in the Desktop upon double clicking the.dmg downloaded from the link above. 20 minutes to let it work and finally. Navigate to the folder where the file, folder or application you want to change resides. At the command prompt, use the cd command (which means change directory) by typing in the text indicated below in bold followed by the Enter/Return key.

I have a USB drive that I purchased and use with various PCs at work and school. I am able to open the drive and can even copy files from the drive. But if I attempt to copy a file to the drive on my Mac, I get an icon telling me that I am not able to copy the file. If I try to delete a file, by pressing Command+Delete, nothing happens and, if I right click the file, the option to move it to the trash can is missing. Something is obviously not right with the storage drive.

If you right click the drive and select Get Info, you can see at the bottom of the info window under the sharing and permissions twirl down, you only have permission to read from this drive and nothing else.

The cause of this is due to the filing system the storage device is formatted in. If you look in the general twirl-down under format you can see that this drive is formatted in the windows NT file system. The NTFS file system is a system specifically optimized for Windows in the way that it organizes the data on the drive. While this file system is readable on Macs because OS X can rearrange the data as it is reading it, the way that NTFS writes the files to the storage device is not; hence, you can read, but not write.

Many storage devices such as USB drives and external hard disk drives come pre-formatted in NTFS because a larger number of consumers are using them on PCs. However, making your storage device Mac compatible, and even cross compatible with Macs and PCs, is as simple as reformatting the drive.

Correcting the 'Read Only' Disk Error

First and foremost before proceeding any further, you are about to format your storage device. Be sure to copy any and all file from the drive as all the data on the drive will be erased. This can be a simple task or a long undertaking depending on the size and usage of the storage device, but is a necessary and important step.

You can reformat a hard drive on Mac OS X by using Disk Utility. In the left-hand side inside of Disk Utility you will see a list of all the connected hard drives. Each physical drive is shown with the partitions of that drive nested below. Highlight the physical drive you wish to reformat and on the menu at the top to the right select erase.

You are about to format your storage device. Be sure to copy any and all file from the drive as all the data on the drive will be erased.

You will see two fields where you can choose a file system format and a field to name the new partition you are going to create. If you are just going to use your drive on Mac computers, you can select one of the Mac OS options. If you wish to create a partition that is cross compatible with Mac computers as well as PCs, you can select either the MS-DOS Fils System format or the exFAT format. You can rename the hard drive to whatever descriptive name you like then click erase and now the drive is formatted in a cross compatible filing system. If you click on the drive and select get info you can now see that the permissions are set to read and write.

Conclusion

The NTFS file system format is a great format to use if you are using your drive solely on Windows based PCs. But if you need to use your drive on Mac OS, or on both PCs and Mac OS, NTFS will unfortunately not be the best format to use. In this tutorial I’ve identified the cause of the “read only” error that Mac users may find when using external storage devices, and also how to easily fix the problem by reformatting your drive to a fully Mac OS compatible format.

Chances are, you were using Mac OS X even before you bought this book, since few Macs sold in the past few years can boot into anything else. And even if you own an older Mac, the fact that you're reading this volume means you've probably already installed Mac OS X on it!

For that reason, I provided an overview of Mac OS X (in Chapter 2) before this description of how to install the operating system, believing that most of you are already up and running in Mac OS X. Even if that's the case, though, you may someday be called upon to install Mac OS X on an older Mac that's still running Mac OS 9. Or, even more important, you may need to re-install Mac OS X (to fix problems). Finally, as new versions of Mac OS X are released, you will need to upgrade your OS. For all of these occasions, this chapter explains what needs to be done (and why) and offers solutions to a variety of potential problems.

I start off by providing background information on installing Mac OS X for the first time, moving on to give more general information about installing, reinstalling, and restoring Mac OS X software. You'll also learn about upgrading Mac OS X and find recommendations about how best to back up Mac OS X.
