High Sierra Format (HSF) is the early logical file system used for CD-ROMs in 1985 and 1986. The later ECMA-119 and ISO 9660 standards are based on revised HSF.
Overview[edit]
Compact Discs were originally developed for recording musical data, but soon were used for storing additional digital data types because they were equally effective for archival mass data storage.
At first, every CD-ROM maker created their own format as there were no high-level standards, only the Yellow Book CD-ROM standard for the lowest level. There was a need for a standard for organizing data on compact disks into logical units such as files.
In order to develop a CD-ROM file system standard (Z39.60 - Volume and File Structure of CDROM for Information Interchange), the National Information Standards Organization (NISO) set up Standards Committee SC EE (Compact Disc Data Format) in July 1985.[1]
In September/[2] October 1985 several companies invited experts to participate in the development of a working paper for such a standard.
In November 1985, representatives of computer hardware manufacturers gathered at the High Sierra Hotel and Casino (currently called the Hard Rock Hotel and Casino) near Lake Tahoe, California.[3] This group became known as the High Sierra Group (HSG).
Present at the meeting were representatives from Apple Computer, AT&T,[citation needed]Digital Equipment Corporation (DEC), Hitachi, LaserData, Microware,[citation needed]Microsoft, 3M, Philips, Reference Technology Inc., Sony Corporation, TMS Inc., VideoTools (later Meridian[4]), Xebec, and Yelick.[citation needed]
The meeting report evolved from the Yellow Book CD-ROM standard for data CDs, which was so open ended it was leading to diversification and creation of many incompatible data storage methods. The High Sierra Group Proposal (HSGP) was released in May 1986.
A draft version was submitted to the European Computer Manufacturers Association (ECMA). With changes this led to the issue of the initial edition of the ECMA-119 standard in December 1986.[5] The ECMA submitted their standard to the International Standards Organization (ISO) for fast tracking, where it was further refined into ISO 9660. For compatibility the second edition of ECMA-119 was revised to be equivalent to ISO 9660 in December 1987.[6][7][8]ISO 9660:1988 was published in 1988. ECMA-119 and ISO 9660 were needed because the HSF was geared primarily towards the needs of the US market. The international extensions are the bulk of the differences between the formats.
In order not to create incompatibilities, NISO suspended further work on Z39.60, which had been adopted by NISO members on 28 May 1987. It was withdrawn before final approval, in favour of ISO 9660.[1]

Have you ever thought of carrying your Mac OS on an external device and gain access to it at any time? If the reaction is yes, then you have arrived at the right post. We will be providing you with the information through which you can install macOS High Sierra on an external drive.
Part 1. How to Install macOS High Sierra on the External Drive
Before beginning the process, there are a few requisites that you must meet. You will need an external drive with a minimum capacity of 16 GB, and second, you will need the copy of the macOS High Sierra installer. You can obtain the installer from the App Store by searching for 'macOS' and download it to your Mac hard drive.
Step 1: Formatting the External Drive

To allow the external drive to function as the startup disk, you need to format it to Mac OS Extended and employ GUID partition map. Start the utility disk. You can find it under the Applications category or search it using Spotlight.

As utility disk runs in the background, you can check for the format of the external drive. In the following example, the drive is in Master Boot Record format. First, unmount the drive. After unmounting, you can select the same drive from the left of the window as shown in the figure below. Now, from the tabs that appear in right window, choose 'Erase' option.
In the next window, you can now format the external drive as 'Mac OS Extended' and opt for GUID Partition Map. If you choose to, you can also give it a name. Press 'Erase' to proceed. After completion, you will see the following screen. Press 'Done' to proceed.

Step 2: Installing macOS High Sierra on the External Drive
After you complete the download of the macOS installer, double click the same from the Applications folder to begin the installation procedure. Press 'Continue' in the following screen.
Click 'Agree' to the accept license agreement. In the next window, press the 'Show all disks' option. The window will display the local drive and the connected external drive. Choose the external drive in this case. You will have to key in your system user name and password.
macOS High Sierra will begin installing on the selected external hard disk. It requires some time to complete the task. You can wait until the process is complete. Before it completes the installation, the Mac will restart. Therefore, it is preferable to save any other work that is in progress.
After restarting, the Mac will take a minimum of 15 minutes to complete the installation process. It will then reboot from the new device. You then have to proceed with the general process of activating Siri, time zone, and adding the user account. Once you complete these actions, you will possess the new version of macOS High Sierra on your external drive. Do not remove the external drive, as Mac OS will access the files on the drive periodically. You can now use the same every time you wish to use High Sierra.
Part 2. How to Use macOS High Sierra with the Bootable Hard Drive
As you now have macOS High Sierra in the form of bootable hard drive, you can use it with another compatible Mac or when the situation demands. However, remember that using the external device as a bootable drive will slow down the functioning of the system. More importantly, it is useful only when you are facing trouble with your existing internal drive of the Mac.
The following information will be helpful in case if you choose to use macOS High Sierra with the bootable hard drive:
Step 1: If there is a trouble with the current hard disk, and you wish to solve it or use the new version of the OS, then plug the bootable external drive to the Mac.
Step 2: Power on the machine and hold the option button until you notice the recovery screen appear. From the screen, you can choose the bootable external device that you have created.
Step 3: You will boot into the macOS High Sierra version for that particular session.
